  • Thermally activated electrical interrupt switch
    Patent number: 7652553
    Abstract: A thermally activated electrical interrupt device incorporates a thermally activated portion (110) engaging with an electrical interrupt portion (120). The thermally activated material (114) expands when heated, causing an interrupt control rod (140, 180) to open an electrical contact (123, 125, 126/132, 134). When the interrupt device is placed into an interrupt state, a reset mechanism maintains the interrupt control rod (140) in the interrupt state until specifically reset.
