Abstract (en)
Electric switching unit for a security means in household appliances comprises a PTC resistor (1), a bimetal strip (2), a bimetal strip (21) compensating for an elevated appliance temperature and a bistable switching spring (3), which is made of a strip spring (31) and a hoop spring (32) coupled to each other by a coupling spring (33). The PTC resistor (1) is placed in a electrically conductive way between the strip spring (31) decisive for the jumping over of the hoop spring (32) and the bimetal strip (2). A first end of the bimetal strip (2) is leaned against an adjusting screw (22) and the second end thereof is leaned against the compensating bimetal strip (21) supported at both ends. The length of the bimetal strip (2) is such that the PTC resistor (1) only slightty influences the temperature of the compensating bimetal strip (21). <IMAGE>
