ABSTRACT:
In a system without longitudinally slidable inserts, a main lever is actuated by a canted notch on a key to swivel in one direction to lock the switch and to swivel by gravity in the reverse direction. A blocking lever is actuated in one direction by the tip of the key and in the opposite direction by a spring.
The main lever and the blocking lever are arranged to cooperate with each other whereby the main lever is blocked by the blocking lever when the switch is locked and the blocking lever is blocked by the main lever when the switch is unlocked.
