    Abstract: A method and a device for secure operation of a switching device including at least two main contacts which can be switched on and off and include contact pieces and a displaceable contact bridge, and a control magnet having a displaceable anchor. The method may include producing an electric control signal to release a contact breaking device when the control magnets are switched on and off. The emitted control signal lies outside the ON state of the switching contact during the regular operation of the switching device and releasing the contact breaking device in defective operation of the switching device if the switching contact remains in the ON state when the control magnets are switched on or off. The switching contact may connect through the control signal to release the contact breaking device.
