A push button (32, 32') has a cam member (32a, 32a') which, when the push button is depressed, rides against a follower (30b, 34b) attached to the slide member, causing the slide member to move to the retracted position against the bias of a spring (30d, 36). The movable contact (22) prevents movement of the slide member to the blocking, protracted position when in the contacts engaged position.Field of SearchWith reset or reclosing meansSnap-action With spring or other energy storage means With bimetallic element With manual or other mechanical contact control means THERMALLY ACTUATED SWITCHES With manual or other mechanical contact control means Reciprocating or sliding motion Bimetallic element unitary with or directly actuates contacts Snap-action With reset means Element attachment or mounting means Housing, casing or support structure | |
