US Patent 9335056 Electromechanical assembly for oven door latching

A latching assembly uses a flat sheet metal chassis with a first and a second electrical switches, an electrical motor driving an eccentric cam, a push rod, a hook, a spring, and a first and a second actuator rods. When the push rod is moved axially by an outside force it opens a circuit connection held closed by the spring on the push rod. This allows current flow to a motor which drives the eccentric cam and pushes an actuator rod to move axially against a hook causing it to move from a first, non-latching position to a second, latching position. The assembly is useful for latching an oven when at high temperature.
