Safety circuit-breaker for water heater, has anchor bolt actuated by electromagnetic coil or pressure pin

摘要

A slider (10) is operated via an anchor bolt (12) when the bolt is actuated by an electromagnetic coil, and/or the bolt is moved by a pressure pin (17) of a pressure sensor. The anchor bolt and pressure pin may be made as one part, and/or may be held in position by a spring which produces a spring force that, together with frictional forces, defines the trigger force.
