ABSTRACT:
A manual reset electrical protector (10, 10') has a reset assembly (26, 26') having a guideway (28a, 28a') and track (28c, 28c') in which a slide member (30, 34, 34') is movable between a protracted position interrupting the movement of a movable electrical contact (22) mounted on a thermostatic disc (20) to preventg engagement of the movable contact with a stationary electrical contact (24) and a retracted position in which the movable contact is allowed to move unfettered into the contacts engagement position. 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.
