Abstract (en)

[origin: EP0930631A2] The switch element (1) has a housing (4) containing a bimetallic strip (6) on a heat conducting plate (5). The edge region of the bimetallic strip is such that the strip bends in one direction when the temperature if above a spring temperature and bends in the opposite direction when the temperature is below the spring temperature. The direction is bending effects the contact path between the fixed and movable contacts. A spreading element ensures that the bimetallic strip contacts the heat conducting plate. The spreading element is in the form of a ring (8) with at least one radially inwardly extending tongues (9,10). The ring lies on the bimetallic strip.
