ABSTRACT:
A safety position switch including a push rod which responds to the movement of an actuator connected to a device to be made safe in order to act upon an electrical device by a lockable transmission mechanism acted on by the push rod. The transmission mechanism includes a pivoting lever capable of assuming a locked position and an unlocked position. The pivoting lever has force applied to it from the push rod such that a movement of translation of the push rod generates a rotation of the lever and the pivoting lever has an arm with a jamming element that is applicable, in the locked position of the lever and transversely with respect to the main axis, against the locking head.
