Abstract

A door latch for a domestic electrical appliance includes a latch assembly that includes a locking element arranged to be displaceable between an unlocking position and a locking position, and an arresting element which moves from its release position into the arresting position as the door is closed. The arresting element in the arresting position can be locked by means of the locking element against movement into the release position and in the locked state prevents the closed door from opening. The latch assembly further includes an electric switch which, when the door is closed, responds to a movement of the locking element from the unlocking position into the locking position, and a switch auxiliary control member which, as the door is closed, is urged by the closing body from an active position against a restoring spring force into an inactive position.
