ABSTRACT:
A circuit arrangement for locking and/or unlocking a door lock, especially in an electric appliance that is provided with a door for closing or opening a work area. Said circuit arrangement comprises an electrically actuated door lock actuator which acts upon a locking member when a current flows through the actuator, said locking member locking or unlocking the door lock. A series connection that is composed of two switching devices is arranged in the triggering circuit of the door lock actuator, said two switching devices being controllable by the control device which emits output signals to actuate the two switching devices once specific triggering signals have been fed to the control device.
