Temperature-dependent switch

摘要

In a temperature-dependent switch having a switching mechanism that has a movable contact part which cooperates with a stationary counter contact and is moved by a spring part to which the movable contact part is electrically conductively connected, the switching mechanism produces an electrically conductive connection between the stationary counter contact and a second counter contact in a temperature-dependent manner. The switch is provided with an arc-shielding plate, which has no mechanical function, is arranged on an upper surface of the spring part and covers sections thereof.

1. A temperature-dependent switch provided with a stationary counter contact, a second counter contact, and a switching mechanism, said switching mechanism comprising a spring part and a movable contact part, said spring part having an upper surface facing said stationary counter contact, wherein said movable contact part is electrically conductively connected to said spring part, cooperates with said stationary counter contact and is moved by said spring part, the switching mechanism producing an electrically conductive connection between the stationary counter contact and said second counter contact in a temperature-dependent manner,
the switching mechanism comprising further an arc-shielding plate having no mechanical function and being arranged on said upper surface of said spring part, said arc-shielding plate covering at least one area of said upper surface, wherein the arc-shielding plate comprises a closed annular region, said closed annular region covering said at least one area on said upper surface of said spring part, said at least one area being an annular area extending around the movable contact part, and wherein the arc-shielding plate comprises three strips extending in a star-shaped manner from the annular region.
