The present invention relates to an actuator 10 for a movably situated device, in particular a device for joining stacked adherends 7, in particular a pair of welding tongs. The object of the present invention is to realize a position-dependent control of a device, the position of which may be changed, while minimizing the additional effort or outlay required. The present invention solves this problem by integrating a measuring means 2 for detecting at least one position-dependent measured quantity in the actuator, it also being possible to derive the position of actuator 10 from the measured quantity. The measuring means is enclosed in actuator 10. This has the advantage that additional interference edges on the device on which the actuator is located may be avoided, and the position-dependent signal may be transmitted to higher-order controller 4 easily along with other signals that are transmitted by the actuator anyway. |
