Embodiment Construction

[0067] figure 1 10 identifies a thermostatic switch, which has a pot-shaped lower part 11 made of electrically conductive material, on which a cover 12 likewise made of electrically conductive material is seated. An insulating film 13 is arranged between the lower part 11 and the cover part 12 , which together with the cover part 12 is held on the lower part by a beaded edge 14 of the lower part 11 .

[0068] A temperature-controlled switching mechanism 15 is provided in the switch 10 , and the temperature-controlled switching mechanism includes a spring flip disc 16 carrying a movable contact piece 17 . A bimetal disc 18 is placed above the movable contact piece 17 .

[0069] exist figure 1 In the closed state of the switch 10 shown, the spring flip disc 16 bears with its edge on the bottom surface 19 of the lower part and presses the movable contact part 17 against the fixed contact part 20, which is arranged on the cover part. 12 on the inner side 21.

Abstract

A temperature-dependent switch (10) with a temperature-dependent switching mechanism (15), which, depending on its temperature, opens or closes at least one switching contact (24), which is formed by two contact parts (17, 20) that are in contact by their switching areas (25, 26) when the switch (10) is closed, has as a heating resistor one of the contact parts (17, 20), which consists at least partially of resistance material. The contact part (17, 20) that is formed as a heating resistor comprises a body that comprises the resistance material and has a top layer of contact material on its switching area (25, 26) ( Figure 1 ).

Description

technical field [0001] The invention relates to a temperature-controlled switch with a temperature-controlled switching mechanism, which opens or closes at least one switching contact depending on its temperature, the switching contact being formed by two contact parts, the two When the switch is closed, the two contact parts bear against each other with their switching surfaces, wherein one contact part is designed as a heating resistor and is at least partially made of resistive material. Background technique [0002] Such a switch is disclosed, for example, in DE19545998C2. [0003] Known switches are used in a known manner to monitor the temperature of the device. To this end, it is in thermal contact with the protected device, so that the temperature of the protected device influences the temperature of the switching mechanism. [0004] This switch is also connected in series to the power supply circuit of the protected equipment through its external terminals, so tha...
