Abstract: A rail switch control mechanism including a locking clamp which is shiftable using a path rod. The locking clamp has, on an end facing the switch tonque, a swivel head. The swivel head is swivelably connected with a switch tongue. In use, the locking clamp cooperates with a locking piece. In the locked position of the clamp, a shoulder of the locking clamp contacts a shoulder of the locking piece. The switch tongue rail is linked to the swivel head with the interposition of a pin arranged with an elongated slot extending longitudinally of the tongue rail. The elongated slot is arranged within a connecting member which is rigidly connected to the switch tongue rail, e.g. by being threadedly connected, to the web of the switch tongue rail.
