Problems solved by technology

[0026] Even with these switches there is still the problem of the unavoidable formation of arcs mentioned at the beginning which limits the lifetime of the known switches to a large extent and the problem of high switching currents

Embodiment Construction

[0081] figure 1 A schematic side view of a thermostatic switch 10 is shown, which is circular in plan view and has a thermostatic switching mechanism 11 arranged in a housing 12 .

[0082] The housing 12 comprises a cup-shaped lower part 14 closed by an upper part 15 . In the lower part 14 there is provided a surrounding shoulder 16 , on which a spacer ring 17 is arranged, on which the upper part 15 rests in the middle of the insulating foil 18 .

[0083] The lower part 14 supports the upper part 15 on the surrounding rim 16 by means of its inwardly curved and upwardly protruding edge 19 .

[0084] The lower part 14 and the upper part 15 are produced in the illustrated embodiment from an electrically conductive material, which is why the insulating film 18 is provided and electrically insulates the lower part 14 and the upper part 15 from each other.

[0085] An insulating cover 22 is also provided on the outer surface 21 of the upper part 15 , and a fixed butt contact 24 i...

Abstract

In a temperature-dependent switch (10) having a switching mechanism (11) that has a movable contact part (25), which cooperates with a stationary counter contact (24) and is moved by a spring part (26, 28) to which the movable contact part (25) is electrically conductively connected, the switching mechanism (11) produces an electrically conductive connection between the stationary counter contact (24) and a second counter contact in a temperature-dependent manner. The switch is provided with an arc-shielding plate (38), which is devoid of mechanical function, is arranged on an upper surface (37) of the spring part (26, 28) and covers sections thereof.

Description

technical field [0001] The invention relates to a temperature-controlled switch having a switching mechanism with a movable contact piece cooperating with a fixed counter contact and moved by a spring element electrically conductively connected to said movable contact piece, The switching mechanism produces an electrically conductive connection between the fixed counter contact and the second contact contact in a temperature-controlled manner. Background technique [0002] A switch of this type is known, for example, from DE 196 23 570 A1. [0003] Known switches have a cup-shaped lower part closed by a flat upper part. A temperature controlled switching mechanism is disposed within the switch and has movable contacts cooperating with fixed counter contacts. [0004] The switching mechanism comprises a flip spring disk which has the contact piece and presses it against the fixed counter contact. In this case, the flip spring disk is supported by its edge on the inner base...
