'i`li e devices have therefore been cl'iiiaclmizcml by constructions in wliieii Clie li laiiee between i'lxe @entail points has been infaeased at the expense o lie'amount of preaame exerted atsueli points when the eleelimnagaela are energized. Thus il, has been folmrl that where only a feeble cari-viii available foi' lie ojwia on of die relay.. ille amount of pieseiiie produced at the point, olf eoalael by auch fievic/es is insullieienl; lo make a reliable Contact In order lo overcome lie clilliuulties above iiimilioiiell. i llave produced (lie device liefe-A iu (lei-: 2iil1a'1rl iii which (lie minable Contact ingy paris ai'e aelnaied lly a ii'ioloi :mrl ila rolaiiig frliaiil: instead of by an electromagiiel'. ily invention iS Se constructed llial; willi a given amount of current applied 'to llie i'noioi'.y the aciuaing power of lli@ liiotoi, wliiili may be slight, is #o applied to the iroaiacing points that ille exerted pressure :it sach points is mueli greater than could lie olifaiiiefl by tile application of the same ammini ol electric power to the Similar paia o'l an, eiecliomaguet.
