Abstract

816,296. Retractive switches; snap-action switches. ILLINOIS TOOL WORKS. March 23, 1956 [March 23, 1955], No. 9171/56. Class 38 (5). A snap-action switch comprises a pair of contact arms 92 pivotally engaging a plunger 64 in grooves 88 and bridging fixed contacts 30. As'shown, the arms 92 are U-shaped and are connected by a centrally-disposed coil-spring 102 passing through a slot 78 in the plunger. Depression of an insulating button 68 on the plunger 64 causes the arms to snap over from one pair of fixed contacts to the other. The contacts 30 (Fig. 9) which are provided with terminal apertures 54, slide into slots in the end wall of the casing and have fingers 56 which resiliently engage apertures 36 in the front and rear walls. As shown, the switch is retractive, having a return-spring 84. Alternatively the plunger may be fitted with a lower button to provide a " push-push " switch. A double switch may be provided (Figs. 11 and 12, not shown) in which two sets of contact arms are superposed and connected by an insulating link. The contacts are cleaned by their wiping action on engagement.
