Removable push-to-unlock actuator for locking pivoted-subactuator self-enclosed electric switch

In a self-enclosed electric switch having a pivoted subactuator including an integral locking mechanism that automatically locks the switch whenever it is operated to one position requiring an additional operation to unlock the switch to allow it to be operated to its other position, a removable push-to-unlock means comprising:

• a combined actuator and lock-release member,
• means for snap-in mounting said combined actuator and lock release member on said subactuator;
• means normally biasing said combined actuator and lock-release member free of said locking mechanism thereby to render the latter effective to lock said switch in said one position;
• means operable when said combined actuator and lock-release member is push-actuated against said bias means for unlocking said locking mechanism thereby to allow pivotal actuation of said subactuator along with said combined actuator and lock-release member to said other position;
• said bias means being effective when said combined actuator and lock release member is released for returning the latter to said free position;
• said snap-in mounting means allowing removable of said combined actuator and lock-release member to prevent unauthorized operation of said switch to said other position;
• and said subactuator comprising means providing a handle when said combined actuator and lock-release member is removed for facilitating actuation thereof from said other to said one position whereupon said switch automatically locks to prevent operation thereof until said combined actuator and lock-release member is again snap-in mounted thereon and push-actuated to unlock said locking mechanism.
