In a railway switch drive, a force sensor (14) is arranged between the drive unit (1) and one of its connecting points (13) to the housing element (7, 4) and connected to a monitoring unit (16), for example in an interlocking cabin, via a motionless signal line (15). In this way, increases in the required actuating force, due for example to soiling, can be easily detected and appropriate maintenance measures triggered. IMAGE
