Abstract
976,364. Snap action switches. ILLINOIS TOOL WORKS Inc. Feb. 28, 1962 [March 1, 1961], No. 7912/62. Heading H2B. An electric switch comprises two flat spaced parallel, fixed contact members 30, 38; a common terminal member 26; a movable member 50; a tension spring 54; a movable contact member 52 pivoted on the member 50, the spring 54 engaging the contact member 52 and the terminal 26 to maintain their pivotal connection and provide snap action; and a spring blade operator 88 carrying a nylon bush 80 engageable with the free end of member 50 to actuate the switch. In the movement of the operator 88, the end of member 50 slides slightly with respect to the bush 80 with resultant wiping action of the contacts. In a modification (Fig. 11) the operator 88 moves the members 50 also of spring blade construction by means of a rigid intermediate member 78.
