Abstract

A door latch for an electrical domestic appliance includes a rotary member rotationally movable in a rotation plane between a closing rotational position and a release rotational position, a movably arranged catch for arresting engagement by an overlifting rotational movement of the rotary member with the rotary member in its closing rotational position, and a locking assembly having a locking member movable between an unlocking position and a locking position. The rotary member is spring-biased towards the release rotational position and which, in the closing rotational position, holds a closure member to keep a door closed and, in the release rotational position, releases the closure member in order for the door to open. The locking member forms a first blocking arrangement by means of which the locking member in its locking position blocks the rotary member against rotation out of the closing rotational position into the release rotational position.
