ABSTRACT:
An actuating mechanism comprises a lower housing portion and an upper housing portion. The lower housing portion is cup-shaped and receives a mounting plate into which a thermostatically working element together with a heating coil are inserted. The lower housing portion comprises leaves which are shielded by an insulating plate. Apertures in the insulating plate allow penetration of a working piston of the working element and of contact pins through the mounting plate during assembly of the housing portions whereat the contact pins engage the contact leaves so that the heating coil is supplied with a voltage only in the assembled condition of the actuating mechanism. A compression spring seves as an abutment for the mounting plate. By means of the compression spring the working element is protected against overload: if the pushing force of the working piston exceeds the biasing force of the compression spring, the mounting plate is shifted against the compression spring, and the contact pins lift off from the contact leaves so that the electrical circuit is disconnected.
