Abstract
182,553. Tucker, J. B. April 2, 1921. Switches, quick-action. - Relates to snap-action switches of the kind in which the operating and contact members are both pivoted and have the same direction of rotation, the movement of the contact member being produced by a compression spring. The invention comprises a detent movable in relation to both the operating and the contact members and adapted to restrain the contact member during the initial movements of the operating-member. The handle a is secured to a spindle b, to which the contact member c is pivoted. Articulated respectively to a projection d, secured to the spindle, and to the part g of the member c are two telescopic arms e, f, between which is disposed the spring j, so that as the arms are extended the spring is compressed. The detent m, pivoted at n, has a lug s coacting with an arm t fixed to the member c, and also has an arm o carrying a pin p which enters a cam-slot q in a plate r secured to the spindle b. In the closed position, Fig. 2, the iug s is behind the arm t and prevents it from moving until displaced by the pin-and-slot connection. In the open position the lug s engages in front of the arm t, as shown in Fig. 3.
