Abstract
183,102. Tucker, J. B. April 2, 1921. Switches, quickaction of the kind having a pivoted operating - member and a pivoted contact-member moving in the same direction in operation, a third pivoted member movable in the opposite direction, and a floating spring element between the third element and the operating-member are so constructed that the spring element forms a toggle arrangement with the third member. As shown, the operating lever a' is fixed to the cranked spindle b' upon which the contact-member c<1> is pivoted. The third member u is pivoted at v and has a slot u<1> by means of which it is driven by a pin a<3> on an extension of the handle-lever. A telescoping compression spring element w is pivoted between the member u and the contact-member so as to constitute a toggle linkage with the member u. In action, the toggle linkage is driven across the dead-centre, and the spring-element produces a quick action.
