The structural unit also including a terminal element connected to the heating winding and having an arc runner continuation, as well as carrying a contact piece of the switch contact. Continuations are provided for positioning the structural unit in a housing, the continuations engaging into guide grooves rigidly provided in the housing. The terminal element, in the region of the contact piece, is pressed against the housing stop and the carrier includes a fork-like free end embracing a catch rib of the housing. The bimetallic element is correctly positioned upon insertion of the structural unit into the housing so that readjustment is not necessary.
