Abstract

The unit comprises a base or armature obtained in one piece by cutting out and bending a flat metal piece folded up into the form of a cage whose two opposite faces are each provided with an orifice, along the same axis of displacement of the plunger core (17), the base carrying in one of the orifices a pole piece (6) cooperating with the moving pole piece (19) of the core, the base having a first arm (11) carrying a bimetallic strip (14) and a second arm (2), the ends of the two arms cooperating via an adjusting screw (15).
