Abstract
A door lock for a household electrical appliance has an electric door switch with two contact elements, a pusher and a pusher control element. The pusher presses against a first contact element that holds the door switch in one of the two switching states. When the pusher is displaced from a first pusher position to a second pusher position, the door switch transfers into the other of the two switching states. The pusher control element, which is movable relative to the pusher, moves from one of the two control positions to the other on closing of the door. The pusher control element has a control path where a first path section blocks the pusher against displacement from the first pusher position to the second pusher position and a second path section provides the pusher with space for a displacement from the first pusher position to the second pusher position.
