Abstract

A circuit breaker lock-out assembly (10) which is engageable with a circuit breaker (12) includes a body (14) having a top (16) and a bottom (18) joined by walls (36,38,40). The walls (36,38,40) define a passageway (42) extending from the body top (16) to the body bottom (18). A button (20) having one end extending into the body passageway (42) through the body top (16) is movable between a lock position and an unlock position. A pair of leaf springs (22) are fixed to the button (20) and extend through the body passageway (42). A nose (24) extends from each of the leaf springs (22). Each pin (34) is engageable with a hole (32) formed in the circuit breaker walls (36,38,40) adjacent the switch tongue (26), wherein slidable movement of the button (20) toward at least one of the lock position and unlock position engages the leaf spring (22) with the nose (24) to move each pin (34) relative to the hole (32).
