Abstract:
Disclosed is an electromagnetic switching device including a number of fixed contact pieces, a solenoid-operated mechanism, a contact support which can be moved counter to restoring devices in at least one embodiment, with the aid of the solenoid-operated mechanism and on which a number of movable contact pieces are arranged, and an off stop for the contact support. A sensor is provided, in at least one embodiment, for detecting the position of the contact support while a control unit is provided which is connected to the sensor and regulates and/or controls the solenoid-operated mechanism during a switch-off process in order to decelerate the contact support before the same hits the off stop. Also disclosed is a method for operating such a switching device. The contact support, in at least one embodiment, transmits only a small momentum to the off stop, thus reducing the load applied to the involved parts. Such a switching device therefore has a longer service life than conventional switching devices.
