The present invention relates to the technical field of temperature controllers, and more particularly, to a backpack power-off reset temperature limiter, which comprises an insulating base, a first terminal, a second terminal, a power-receiving elastic piece and an arch-shaped temperature sensing sheet. The power-receiving elastic piece is arranged on the upper end surface of the insulating base. One end of the power-receiving elastic piece is fixedly connected with the first terminal, and the other free end of the power-receiving elastic piece is electrically connected with the second terminal. The two ends of the power-receiving elastic piece are respectively provided with a fixing clamping position that is clamped with an end part of the temperature sensing sheet, and the two sides of the power-receiving elastic piece are respectively provided with an assembly clamping position that is matched with the temperature sensing sheet.

A switching device for an electrical appliance has a housing and an adjustably designed switch therein that operates cyclically. An adjusting device for setting a different cycle behavior of the switch is provided that acts mechanically on the switch. It has a rotary shaft with a varying contour device that has along the circumferential direction a varying contour. An electrothermic tripping device is provided for the switch and has a heating element and two electrical connections thereto. At least one connection has two disconnectable connecting contacts in the current path of the connection. The switching device has a disconnector which acts mechanically on one of the connections of the tripping device in order to disconnect its two connecting contacts. The disconnector can be moved in a disconnecting rotary angle range of the rotary shaft by the contour device, in order to disconnect the connecting contacts in the disconnecting rotary angle range, and otherwise not.

A heat-reactive switch includes an airtight container with a housing and a lid plate, two conductive terminal pins fixed in through-holes in the lid plate, a fixed contact point fixed on one of the conductive terminal pins, a heater connected to the other conductive terminal pin and to the lid plate, a heat-reactive plate connected to the housing internal surface, the bending direction becoming inverted at a predetermined temperature, and a mobile contact point provided at the end of the heat-reactive plate. A heating element has a plurality of serpentine portions made from a metal plate in ribbon form, disposed between the lid plate and the heat-reactive plate so as to be parallel thereto. At least two of the serpentine portions are disposed to face each other while sandwiching the conductive terminal pin. Each portion follows the inner peripheral surface of the housing and have planar portions facing each other.
