Heretofore, manually operated rotary switches universally include some type of knob or handle which is mounted on the frame of the switch for rotation in a plane generally parallel to the plane of the switch sections so as to rotate the drive shaft and thus the rotor of one or more switch sections which is driven by the drive shaft. In some situations, it would be desirable to permit actuation of the rotary switch by using a more positive linearly movable toggle operating type member. Conversely, most conventional toggle switches utilize leaf or similar type of contact members which are closed or opened in response to the linear, pivotal movement of the toggle lever. In some situations, a rotary switch has greater operative advantages than leaf-type contact switches which are operated by toggle levers. This invention is directed to solving these problems by providing a toggle operating type rotor actuating means for rotary switches, including novel connecting or link means which translates linear, pivotal movement from the toggle lever to rotary movement of the switch rotor for one or more switch sections operated by a single toggle-mounted lever.

Another object of the invention is to provide a rotary switch which includes at least one generally planar switch section disposed along a drive shaft with the rotor of the switch section being driven by the drive shaft, and including a toggle operating type rotor actuating means for rotating the drive shaft. A toggle lever is pivotally mounted on a frame for the switch for generally linear reciprocating movement. A yoke is fixed to the drive shaft and extends outwardly therefrom for rotation therewith. A connecting means is provided between the toggle lever and the yoke for translating linear movement from the lever to rotational movement of the yoke, shaft and rotor through a segment of an arc.

A further object of the invention is to provide a rotary switch as set forth in the preceding paragraph wherein the pivot mounting for the toggle lever is disposed concentric with and at one end of the drive shaft. The aforementioned yoke comprises a driven yoke member, and including a drive yoke member pivotally mounted on the switch frame at a point spaced from the drive shaft for rotational movement in a plane transverse to the axis of the shaft. Connecting means are provided between the driven and drive yoke members spaced from the drive shaft'and the pivot point of the drive yoke member to provide for simultaneous rotation of the yoke members. Connecting means is provided between the toggle lever and the drive yoke member for translating linear movement from the toggle lever to rotational movement of the drive yokemember, driven yoke member, shaft and rotor.

Still another object of the invention is to provide a rotary switch as set forth in the preceding paragraph wherein the connecting means between the driven and drive yoke members includes an arm extending away from one of the members axially of the drive shaft and received in a radial slot in the other of the yoke members. The connecting means between the toggle member and the drive yoke member comprises a radially disposed slot in the drive yoke member intersecting the axis of the drive shaft and receiving the toggle lever at a point spaced from its pivot mounting on the switch frame.

With the structure as set forth in the preceding paragraphs,

the rotors of a plurality of switch sections axially disposed secured to each of the concentric shaft members as described above. The radially disposed slots in the drive yoke members are oriented so that all intersect the axis of the drive shaft and all receive the one end of the toggle lever. The drive yoke members are disposed at various angular orientations with respect to the axis of the drive shaft. The toggle lever is journaled on the switch frame at a point concentric with the axis of the drive shaft for universal movement to provide linear movement in a number of planes all parallel to and intersecting the axis of rotation of the concentric drive shaft members. By properly angularly orienting the drive yoke members, linear movement of the universally joumaled toggle lever in a given one of said planes will cause movement of only one of said drive yoke members through a segment of an arc and thereby actuate only one rotor of one of the plurality of switch sec tions.

Further objects, advantages and features of the invention will become apparent from the following detailed description taken in connection with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION The toggle operating type rotor actuating means of this invention is shown embodied in a rotary switch, generally designated 10 in FIG. 1. The rotor actuating means is shown as providing switching functions of a plurality of generally planar switch sections. Two switch sections, generally designated 12:; and 12b, are illustrated in the drawings and are shown best in FIGS. 6 and 7. The switch sections 12a, I2b each eomprise a stator portion 14a, 14b, respectively, and a rotor portion 16a, 16b, respectively. In conventional manner, the rolQls of each switch section carry a plurality of flat segmental contacts 17 on opposite sides thereof and about the outer periphery thereof for selectively making contact with a plurality of conventional double-wipe contacts 18 mounted on the stators of the switch sections. Referring to FIGS. 6 and 7, contact extensions 20 are disposed at the outer edge of each segmental contact l7 and are adapted to engage the jaws of the double-wipe contacts 18. Of course, the number of contacts Ill and contact extensions 20, as well as their angular disposition about the stator and rotor, are a matter of choice depending npon the use of the switch and the switching functions desired.

The switch sections 12a, 12b are disposed along a drive shaft means, generally designated 22, with the rotors of the switch sections being rotated back and forth in the direction of arrows A (FIGS 6 and 7) by the drive shaft rneans, as described in greater detail hereinafter. The switch sections are held in place along the drive shaft means 22 by a pair of boltlike strut members 24 which are mounted on a rear frame portion which includes front and rear frame plates 26 and 28, respectively. Spacer sleeves 30 maintain the positioning of the switch sections 12a, 12b on the strut members 24 to maintain their axial disposition along the shaft means 22.

At this time it should be pointed out that the shaft means 22 includes a pair of concentric relatively rotatable shaft members 32a and 32b. The outer shaft member 32a comprises a sleeve for the inner shaft member 32b and has a double-D exterior, as best seen in FIG. 7, which mates with a similarly shaped aperture in the rotor 16a. The inner shaft member 32b extends beyond the rear end (the left end in FIG. 1) of the outer sleeve shaft member 32a and has flat surfaces 34 for engaging similar abutment surfaces on the rotor 16b to translate rotational movement thereto.

The switch has a front frame portion which includes four post members 36 which are secured to the frame plate 26 and which mount a front guide plate 38 (FIG. I), a toggle-mounting plate 40 behind the front guide plate 38, and an intermediate mounting plate 42 which mounts the drive yoke members, to be described in greater detail hereinafter.

The toggle operating type actuating means of this invention includes a toggle lever 44 which is joumaled by a toggle ball 46 in a concave socket portion 48 of the toggle-mounting plate 40, for universal movement of the toggle lever 44 about the toggle ball 46. The ball 46 and socket 48 are disposed concentric with the axis of the shaft means 22 whereby the toggle lever 44 is disposed coaxial with the axis of the drive shaft means 22 at the front end of the shaft means when the toggle lever is in its center or home position shown in FIG. 1.

Referring to FIGS. 1 and 8, the front guide plate 38 has a pair of guiding slots 48a and 48b disposed at 90 to each other and intersecting at and extending about the toggle lever 44 which extends forwardly through the front guide plate 38. These guide slots 48a, 48b restrict the universal movement of the toggle lever 44 to two linear directions, one for each of the switch sections 12a, 12b, respectively, to rotate the rotors of the respective switch sections zndependently of each other in response to linear movement of the toggle lever pivotally about toggle ball 46 in one or the other directions defined by the guide slots 48a, 48b, as set forth below.

The connecting means between the toggle lever 44 and the shaft members 32a, 32b (along with their respective rotors 16a, 16b, respectively) will now be described. It first should be pointed out that the suffix letters a and b, as used above, are used for those members which cooperate to actuate the respective rotors 16a, I6b of the switch sections 12a, 12b, respectively. Referring to FIGS. I and 5, a pair of drive yoke members 50a, 50b are mounted by riveted shaft members 52a, 52b, respectively, to the mounting plate 42 at points spaced from the axis of the drive shaft means 22. The short rivet shaft members 52a, 52b are angularly disposed about the axis of the drive shaft means 22, 90 from each other, with the drive yoke members 50a, 50b extending radially therefromto opposite sides of the shaft means and intersecting on the axis of the shaft means, as best seen in FIG. 5. Each of the drive yoke members 50a, 5012 has a radial slot 54a, 54b, respectively, which receives or through which extends the inner end of the toggle lever 44 at points spaced to the rear of the pivoted toggle ball 46. The slots 54a, 54b provide for motion of the lever radially in the slots with the sides of the slots engaging the lever to translate linear movement from the lever (as defined by the guide slots 48a, 48b in the front guide plate 38) to rotational movement of the drive yoke members.

Referring to FIGS. 1 through 4, a pair of driven yoke members 56a, 56b are fixed to the front ends of the outer and inner shaft members 32a, 32b, respectively, for rotational movement with the shaft members in a plane transverse to the axis thereof. Referring to FIG. 2, each of the driven yoke members 56a, 5612 has a radially disposed slot 58a, 58b, respectively, at the radially outer edges thereof receiving arm portions 60a, 60b which protrude rearwardly from the drive yoke members 50a, 50b, respectively. As with the slots 54a, 54b in the drive yoke members, slots 58a, 58b provide for motion of the arm portions 60a, 60b radially in the slots, but with the sides of the slots 58a, 58b being engaged by the arm portions 60a, 60b to translate simultaneous rotational movement from the drive yoke members 50a, 50b to the driven yoke members 56a, 56b,

and thus, in turn, to the drive shaft members 32a, 32b and the rotors 16a, 16b of the switch sections 14a, 14b, respectively.

The full operation of the toggle rotor actuating means of this invention will now be described. The operation will be described only in relation to the switch section 12b. Referring to FIG. 1, linear movement of the outer end of the toggle lever 44 in the direction of arrow C within the guide slot 48b in the front guide plate 38 will cause the lever to pivot about toggle ball 46 and correspondingly move the inner end of the lever in the direction of arrows E (FIGS. 1 and 5). The inner end of the toggle lever 44 will engage the sides of the slots 54b in the drive yoke member 50b and cause the drive yoke member 50b to pivot about the short rivet shaft 52b (FIG. 5). As the drive yoke member 50b pivots or rotates about shaft 52b, its arm portion 60b (FIG 2) will move in the direction of arrow D (FIG. 2) and engage the sides of the slot 58b in the driven yoke member 56b which is secured to the front end of the inner shaft member 32b. Rotation of the driven yoke member 56b in the direction of arrow D (FIG. 2) correspondingly will rotate the inner shaft member 32b and cause rotation of the rotor 16b of the switch section 12b to make or break selective contacts 18 and 20.

Referring to FIGS. 1 and 4, it can be seen that movement of the toggle lever in the direction of arrow C (FIG. 1) downwardly in guide slot 48b will cause movement of the driven yoke member 56b upwardly to the position shown in full lines in FIG. 4. Movement of the toggle lever upwardly in guide slot 48b will cause the driven yoke member 56b to move to the position shown in phantom in FIG. 4. correspondingly, referring to FIG. 3, horizontal movement of the lever (i.e. movement in guide slot 480) will cause movement of the driven yoke member 56a between the full line and phantom positions shown in FIG. 3.

Specialized switching functions also may be incorporated with the present invention. For instance, projecting arms 70 may be provided on the toggle ball 46 and an hourglass spring member 72 may be positioned between the projecting arms 70 and the inside of the front guide plate 38 to urge the toggle lever 44 to its center or home position as shown in FIG. I. In the embodiment illustrated, the biasing of the hourglass spring 72 is provided to function with the switch section 12b. Alternatively, a conventional detent structure which includes a detent plate 74 (FIG. I), detent balls 76, ball carrier plate 78, and plate spring may be employed to hold the toggle lever in one or both of its extreme positions. In the embodiment illustrated, the detent structure is mounted to the outer shaft member 32a and thereby controls or holds the switch positions for the switch section 12a.

,It should bepointed out that only two switch sections have been shown in the drawings and described above for illustration purposes only. It is contemplated that with the present invention more than two switch sections, concentric drive shaft members, driven yoke members, drive yoke members, and guide slots (i.e. 48a, 48b) may be employed for a wide number of switch sections.

The foregoing detailed description has been given for clearness of understanding only and no unnecessary limitations should be understood therefrom as some modifications will be obvious to those skilled in the art.
