Abstract
In a device for checking the operation of devices (4) used to displace movable switch parts (2, 3), in which the movable switch parts (2, 3) are connected with each other by a coupling rod (13), the coupling rod (13) is comprised of two coupling rod parts (14, 15) that are relatively movable in the axial direction. Sensors (34, 35) are provided for the detection of at least two different displacement positions of the coupling rod parts (14, 15).
