Embodiment Construction

[0121] figure 1 A thermostatic switch 10 is shown comprising a housing 11 comprising a lower part 12 made of an electrically conductive material and an upper part 14 made of an electrically conductive material.

[0122] The insulating film 15 is arranged between the upper part 14 and the lower part 12 and electrically insulates the upper part 14 from the lower part 12 .

[0123] A fixed contact block 17 is arranged on the upper part 14 on its inner side 16 , said contact block having a first contact region 18 facing the lower part 12 .

[0124] The contact block 17 is then electrically connected to the upper part 14 so that its outer side can act as a first external connection 19 .

[0125] The lower part 12 has a second contact zone 22 on its inner side 21 . Since the lower part 12 is likewise electrically conductive, its outer side serves as a second external connection 23 .

[0126] Arranged in the housing 11 is a temperature-controlled switching mechanism 25 which, depe...

Abstract

A temperature-dependent switch has a housing which accommodates a temperature-dependent switching mechanism and which comprises an upper part with a first external connection and a lower part with a second external connection. The switching mechanism has a bimetallic snap-action disc and a spring snap-action disc having a bearing region on which a movable contact part is captively held. The contact part interacts with a first contact area provided on an inner side of the upper part, and the spring snap-action disc interacts with a second contact area provided on an inner side of the lower part. The bimetallic snap-action disc interacts with the spring snap-action disc in such a way that it lifts the movable contact part off from the first contact area depending on its temperature. The bimetallic snap-action disc is captively held with play on the contact part.

Description

technical field [0001] The invention relates to a temperature-controlled switching mechanism for a temperature-controlled switch having a housing that accommodates the switching mechanism and includes an upper part with a first external connection and a second external connection. a lower part, wherein a first contact area connected to the first external connection is provided on the inner side of the upper part, and a second contact area connected to the second external connection is provided on the inner side of the lower part, wherein the The switching mechanism comprises a bimetallic snap disc and a spring snap disc, the spring snap disc is provided with a bearing area on which the movable contact is captively held, wherein the contact is connected to the first contact area interaction, the spring snap disc interacts with the second contact zone, wherein the bimetal snap disc interacts with the spring snap disc, whereby the bimetal snap disc lifts the movable contact from ...
