Abstract

A device is for controlling the movement of a blocking mechanism in an electric switch which is displaceably arranged in a switch cell. The device includes a push element and an oblique surface, whereby the oblique surface extends in the fitting position of the device in the direction of the travel of the switch and the push element can be maintained in a displaceable manner dependent on the position of a door of the switch cell in the switch cell. The push element co-operates with the oblique surface, acting on the blocking mechanism in such a way that the blocking mechanism is located in a release position when the door is closed and in a blocking position when the door is open. The device can be constructed in a simple manner by virtue of the fact that the oblique surface is inclined in a perpendicular position with respect to the direction of travel of the switch and the displacement path of the push element extends in a transversal manner with respect to the direction of travel.
