  • Patent number: 6249211
    Abstract: A temperature-dependent switch 10 has a temperature-dependent switching mechanism 11; a housing 12, receiving the switching mechanism 11 and having a lower part 14 and an upper part 15; and two stationary contacts 31, 32, provided on the upper part 15 on its inner side 37, each contact being connected to an associated external termina 35, 36. A current transfer member is arranged on the switching mechanism 11 and moved by it, which transfer member is in contact with the two stationary contacts 31, 32 in temperature-dependent fashion. There is arranged physically in the region of the current transfer member and upper part 15 at least one resistor 38 which is electrically connected between the stationary contacts 31, 32 at least when the current transfer member is in contact with them.
