Abstract

A thermal switch arrangement for electromagnetic coils of electric motors, including at least one coil, which has a winding (52, 54) and a coil former (30, 48) in the form of a winding core (32), which is enclosed by two end flanges (36, 38; 56, 58, 60, 62), and flat plugs (26, 28; 74, 76, 78), which are connected with the two ends of the winding and/or the connections of a thermal switch (80), assigned to the winding, and are inserted and locked in pockets (40, 42; 64, 66) in or at at least one end flange (36, 38; 56, 58, 60, 62) from the peripheral edge of the latter and locked. Two tags (82, 84) of the thermal switch (80) enter the pockets (40, 42; 64, 66) of the flat plug (74, 78) from the inner surface of the one end flange (36, 60).
