  • Thermally actuated switch
    Patent number: 4509029
    Abstract: A thermal switch includes a reed switch surrounded by a centrally located, annular collar made of a ferrite material and a pair of annular permanent magnets spaced from the ends of the ferrite collar and positioned axially toward the ends of the reed switch. The magnetic spacing can be achieved by utilization of non-magnetic spacers, and the entire structure encapsulated to provide further durability, if desired.
