摘要： Device responsive to a switching state with an alarm, ud in refrigeration appliances such as freezers or the like. Said switching means compris a contactor (72) movable between first, cond and third positions in respon to changes in pressure of a bellows (20). The bellows pressure increas and decreas in respon to temperature changes detected in the device. The device compris a first t of switching contacts (38, 40) for supplying a compressor and a cond t of alarm contacts (50, 52) for feeding an alarm circuit. The contactor includes a first detent (98) opening and closing the t of contacts as control the contactor moves incrementally by snap between the first and cond positions. An alarm spring (52) oppos the displacement of a cond detent (100) of the contactor beyond the cond position by a preload force until the excess energy click of the switch is dissipated. Then said alarm spring (52) oppos said contactor (72) an elastic gradient until said switch reaches the third position and clos the alarm contacts (50, 52). Closing alarm contacts (50, 52) to the effect of feeding an alarm circuit signaling the temperature of the apparatus exceeds the temperature of the cycle, and it is likely that the system component is in breakdown.
