This invention relates to electromagnetic of. insulating strips 17 and heldirmly in devices of the circuit4 controlling type. place by any suitable means, such as clamp- It is an object of the invention to provide ingvscrews 18. The pile-up comprises a pair anew and improved relay which is adapted of main springs 19 and 20 adapted to alterto Vmakev andbreak a plurality of circuits sinately engage contactsprings 21 and 22 and 60 multaneously. v. Y y 'springs'., and 24, respectively. The ymain More specifically, `the invention contemsprings 19 and120 are at all times in engage plates a relay which maybe operated by cur-v ment with the rollers 12 and13 carried by rents o1 opposite` polarity to perform afpluthe armature 7 and are flexed to normally u) rality of 'switching operations'and to this end ven'gagethe inner contact springs 22 and 23, 65 employs a vbank of springs so disposed that respectively, but are held ont of engagement alternate contacts are opened and closed, therewith and midway between their assorespectively, by Van operation of the armayciated contact springs when the laterally ture in each direction. g moving armature 7 is in the neutral position 15 Anotherfeature of the invention is a deshown inrFig. 1. Since the armature 7 is 70 vice which is quick and positive in action, normally biased, however, it will be evident and in which the contact springs may carry that each main spring contact will always y considerable current, knecessitating sulicient Abe in engagement with one or the other of pressure toinsure proper' conduction without its associatedk contact members. Thus when sparking and consequently employing relathe armature is attracted by the energiza- 75 tively strong springs and electromagnetic detion ot coil 6, main spring 19 will make with vices'having considerable power. the associated contact spring 22, and main Other features ofthe invention relate to f Spring 20 will be moved into engagement the details of construction andcombinationwith its associatedcontact spring 24. By k of parts whereby a minimum ynumber of this movement of the armature contact 21 80 parts are used, all of. which maybe easily will be opened and contact 22 closed, contact formed and assembled. i 23 opened and contact 24 closed. Whenar- Other objects and features of the invention mature 7 is moved by the energizationot will appear from a consideration or' the tolwinding 5 the positions of the contact springs lowing'description taken in conjunction with will be reversed, springs 21y and 23 being 35 the accompanying drawing and the append# closed and springs 22 and 24 being opened .ed claim. by main springs 19 and 20. Thus, although In'the drawing, Figs. land 2 are topplan as previously noted, both main springs arc andside elevation views respectively o1' a deso flexed. as to normally engage their respec- 35 vice embodying-the invention, the enclosingl tiveinner contact springs, still one main 90 cover ltherefor heilig shown in section; and Spring will always be held in engagement Fig. 3 is a detail perspective view ofthe ar-. with an outer contact against its normal tenmature employed in the device. j si'oneven when the electromagnet is deenery Referring' to the drawing, 5 and r6 desiggized.
