Embodiment Construction

[0055] exist figure 1 10 denotes a temperature-controlled switch, which includes a temperature-controlled switch-on mechanism 11 mounted in a housing 12 .

[0056] The housing 12 comprises a lower part 14 and an upper part 15 closing the lower part, the upper part being held on the lower part by a beaded edge 16 of the lower part 14 . A ring 17 is arranged between the lower part 14 and the upper part 15, which rests on a flange (Absatz) 18 of the lower part 14 and guides the opening of the switching mechanism 11 here on the edge 19 of the spring flap 21 of the switching mechanism 11. Spring turnover sheet 21.

[0057] The switch-on mechanism 11 comprises, in addition to the spring flap 21, a bimetallic flap 22, which together with the spring flap 21 is passed centrally by a journal-like (zapfenartig) rivet 23, through which the spring flap and the bimetallic flap pass. The rivet is mechanically connected to the current-transmitting segment in the form of a contact disc 24 . ...

Abstract

The temperature-dependent switch (10) comprises a housing (12) comprising a temperature-dependent switching mechanism (11). A ring (17) is arranged between upper and lower portions of the housing. The stationary contacts (31, 32) are provided at the inner side (37) of upper portion of housing and are connected to external terminals (35, 36). Two circular snap discs (21, 22) are provided on the switching mechanism and are supported by a shoulder (28). The uneven portions are provided at edges (19, 27) of circular snap discs respectively.

Description

technical field [0001] The invention relates to a temperature control switch, which has a temperature control switching mechanism with a circular turning piece; a housing for accommodating the switching mechanism, the housing has a lower part and an upper part; two parts are arranged on the upper part Fixed contacts on its inner side, each of which is connected to a corresponding external terminal; a current-carrying segment arranged on and moved by the flipper, wherein the flipper is supported with its edge on a support in the switch Depending on the temperature, the current-carrying segment is pressed against and / or lifted from the two fixed contacts. Background technique [0002] Such a switch is disclosed in DE2644411C2. [0003] The known switch has a housing with a cup-shaped lower part into which a temperature-controlled switching mechanism is inserted. The lower part is closed by the upper part, which is held on the lower part by the raised edge of the lower part. ...
