Abstract

A door lock for a domestic electrical appliance comprises a movably arranged locking member, which is selectively adjustable into an unlocking position and a locking position and in the unlocking position permits the opening of a closed door of the domestic appliance and in the locking position is in blocking engagement with a blockable component, at least when the door is closed. The blocking engagement causes the closed door to be blocked against opening. The door lock further comprises an electrically controllable actuator for actuating the locking member, and an electrical door detection switch that switches depending on the closing of the door. The doer lock also comprises an electrical auxiliary switch device, which selectively opens or closes an electrical shunt path to the door detection switch depending on the position of the locking member.
