Problems solved by technology

[0037] Although this measure yields good results, it cannot be applied to particularly pressure-sensitive switches with a thermistor cover, since the thermistor material is chemically incompatible with epoxy resins
[0038] The switch with the thermistor cover is therefore cast from silicone, which, although it produces the required electrical insulation, does not in any case produce the desired improvement in mechanical stability.

Embodiment Construction

[0094] figure 1 Shows a schematic side view, not to exact scale, of a thermostatic switch 1 comprising a cylindrical wall 10, an electrically conductive, pot-shaped lower part 11 surrounded by a disc-shaped, electrically conductive A cover 12 is closed, which is held on the housing lower part 11 by the beaded edge 14 of the wall 10 under the lining of the insulating film 13 .

[0095]In the housing of the switch 1 formed by the lower part 11 and the cover 12, a temperature-controlled switching mechanism 15 is provided, which includes a spring flip disc 16, which carries a movable switch in the center. A contact piece 17 on which a freely embedded bimetallic disc 18 is seated.

[0096] Within the scope of the present invention, a bimetallic disc is to be understood as a multilayer, movable, plate-like component consisting of two, three or four inseparably connected parts with different coefficients of expansion composition. The individual layers of metal or metal alloys are ...

Abstract

The switch (1) has housing that is provided with a cover portion (12) and a base portion (11). A temperature-dependent switching mechanism (15) is arranged in the housing, and is set in electrically conductive connection between the cover portion and the base portion. Two housing outer ports (22,23) are arranged on the top surface (25) of switch main portion, and are connected with two connecting wires respectively. A protective cap made of steel is arranged on the top surface of the cover portion for covering the housing outer ports and the connecting wires leading out sideways. An independent claim is included for a method of assembling temperature-dependent switch.

Description

technical field [0001] The invention relates to a temperature control switch, which has a housing with a cover and a lower part; a temperature control switching mechanism arranged in the housing, and the temperature control switching mechanism establishes or disconnects two switches according to its temperature. At least one of the two external terminals is provided on the top surface of the switch and connected to the connecting twisted wire. Background technique [0002] Such a switch is disclosed, for example, in DE 103 01 803 A1. [0003] Thermostats are used in a known manner to monitor the temperature of the device. For this purpose, it is in thermal contact with the protected device, for example via its outer surface, so that the temperature of the protected device influences the temperature of the switching mechanism. [0004] This kind of switch is connected in series with the power supply circuit of the protected equipment through the stranded wire welded to its ...
