ABSTRACT:
A locking mechanism for a limiting contact maker is divulged comprising two levers which act respectively on two pusher blocks actuating the switches of a change-over contact maker. Each of these levers, articulated about a fixed shaft, comprises a roller applied to the profile of a rotary cam by a spring. This cam may pass from a locked automatic operational position in which it allows the switches to close by maintaining the levers away from the pusher blocks, to a tripped position in which the lever acts on the pusher blocks for holding the switches in the open position.
