Abstract
A mechanical interlock (6) for coupling a pair of contactors (2, 4) to prevent concurrent closure thereof. The interlock includes a generally T-shaped one-piece molded frame (16) having a pair of mounting hooks (16a, 16b) at one side at the ends of its arms for coupling to false-front upper corners (2c, 2d) of a first contactor (2) and another pair of mounting hooks (16c, 16d) at the other side at the ends of its arms for similarly coupling to the other contactor (4). Snap-in lugs (16e, 16f) snap into a rectangular aperture (2b) in the contactor wall to retain the interlock in place. A rockable, spring-biased interlock pawl (18) snap-in mounted within the frame has projecting wings (18e, 18f) that extend into the contactor aperture (2b) below a contact carrier projection (8a) so that downward actuation of the contact carrier of one contactor rocks the pawl so as to compress its bias, return spring (20) and cause a toe (18d) at the lower end of the pawl to slide down one side of a double-incline bump (16k) into a pocket at the bottom of the frame thereby preventing depression of the other wing of the pawl by the other contactor and prevent closure of the other contactor at the same time.
