Temperature-dependent switching mechanism

A temperature-dependent switching mechanism for use with a temperature-dependent switch, said switch having a first and a second contact area,

• said switching mechanism comprises a snap-action disc, a bearing region being provided on said snap-action disc, said bearing area having a circumferential region and being separated from said snap-action disc by a gap extending over a part of said circumferential region, and a movable contact part being captively held at said bearing area,
• with said switching mechanism mounted in said switch, said contact part interacts with said first contact area and said snap-action disc interacts with said second contact area such that the snap-action disc lifts the movable contact part off from the first contact area depending on its temperature.

A temperature-dependent switch comprising a temperature-dependent switching mechanism and a housing which accommodates the switching mechanism and which comprises an upper part with a first external connection and a lower part with a second external connection, wherein a first contact area connected to the first external connection is provided on an 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,

• said switching mechanism comprises a snap-action disc, a bearing region being provided on said snap-action disc, said bearing area having a circumferential region and being separated from said snap-action disc by a gap extending over a part of said circumferential region, and a movable contact part being captively held at said bearing area,
• said contact part interacting with said first contact area and said snap-action disc interacting with said second contact area such that the snap-action disc lifts the movable contact part off from the first contact area depending on its temperature.

A temperature-dependent switching mechanism for use with a temperature-dependent switch, said switch having a first and a second contact area,

• said switching mechanism comprises a snap-action disc, a bearing region being provided on said snap-action disc, said bearing area having a circumferential region and being separated from said snap-action disc by a gap extending over more than 180° of said circumferential region, and a movable contact part welded onto said bearing area,
• with said switching mechanism mounted in said switch, said contact part interacts with said first contact area and said snap-action disc interacts with said second contact area such that the snap-action disc lifts the movable contact part off from the first contact area depending on its temperature.

A temperature-dependent switching mechanism for use with a temperature-dependent switch, said switch having a first and a second contact area,

• said switching mechanism comprises a spring snap-action disc and a bimetallic snap-action disc, a bearing region being provided on said spring snap-action disc, said bearing area having a circumferential region and being separated from said spring snap-action disc by a gap extending over more than 180° of said circumferential region, and a movable contact part welded onto said bearing area,
• with said switching mechanism mounted in said switch, said contact part interacts with said first contact area and said spring snap-action disc interacts with said second contact area such that the bimetallic snap-action disc lifts the movable contact part off from the first contact area depending on its temperature.
