1. Safety position switch comprising, in a casing:
a push rod which responds to movement of an actuator connected to a device to be made safe, in such a way as to become displaced
along a main axis in order to assume a rest position and a working position,
an electrical device switchable according to the position of the push rod, by means of a lockable transmission mechanism actuated
by the push rod,
a device (20) for locking the transmission mechanism, said locking device having a head for locking the transmission mechanism, capable
of assuming a locked position and an unlocked position,
characterized in that:
the transmission mechanism comprises a pivoting lever capable of assuming a locked position and an unlocked position,
the pivoting lever has a force applied to the lever from the push rod such that a movement of translation of the push rod
generates a rotation of the lever,
the pivoting lever is provided 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.
