An oven door latching system has a latch bolt with a latch arm at one end and its other end pivotably connected to a lever through a resilient connection. The lever in turn is pivotably connected to a positioning device which has a positioning slide reciprocatable in a housing and biased towards the lever. A recessed camming surface in the slide seats a follower arm which is adapted to follow a camming surface therein which define two stable positions for the follower arm which are spaced apart in the direction of motion of the slide and at which the follower arm will seat and releasably lock the slide. When the positioning slide is moved, pivotal motion is imparted to the other end of the lever, and the connecting structure enbables pivotal motion of the latch bolt. An actuating element acts on the slide to move the slide relative to the follower arm between its stable positions and concurrent motion of the lever to enable movement of the bolt between an oven door latching position and an oven door unlatching position.
