Abstract (en)
[origin: WO2006133659A1] Disclosed is an electromagnetic switching device (1, 2, 3) comprising a number of fixed contact pieces (12), a solenoid-operated mechanism (6), a contact support (4) which can be moved counter to restoring means with the aid of the solenoid-operated mechanism (6) and on which a number of movable contact pieces (9) are arranged, and an off stop (14) for the contact support (4). A sensor (32) is provided for detecting the position of the contact support (4) while a control unit (25) is provided which is connected to the sensor (32) and regulates and/or controls the solenoid-operated mechanism (6) during a switch-off process in order to decelerate the contact support (4) before the same hits the off stop (14). Also disclosed is a method for operating such a switching device (1, 2, 3). The contact support (4) transmits only a small momentum to the off stop (14), thus reducing the load applied to the involved parts. Such a switching device (1, 2, 3) therefore has a longer service life than conventional switching devices.
