TEMPERATURE-DEPENDENT SWITCH COMPRISING A SPACER RING

摘要

A temperature-dependent switch has a temperature-dependent switching mechanism arranged in a housing having an upper part and a lower part. A first contact area is arranged on an inner side of the upper part and a second contact area is arranged internally in the lower part, the switching mechanism producing, in temperature-dependent fashion, an electrically conductive connection between the first and second contact areas. The switching mechanism comprises a current transfer element, a bimetallic snap-action disc and a movable contact area. The moveable contact area is connected to the current transfer element and interacts with the first contact area, the bimetallic snap-action disc lifting off the movable contact area from the first contact area depending on the temperature of the bimetallic snap-action disc. A resistance ring is arranged between the upper part and the lower part and is electrically in series with the current transfer element between the first and second contact areas when the switch is in its closed state.

1. A temperature-dependent switch having a closed state, said switch comprising:
a temperature-dependent switching mechanism, said switching mechanism comprises a current transfer element, a bimetallic snap-action disc and a movable contact area connected to the current transfer element, a housing accommodating the switching mechanism and comprising an upper part with an inner side and a lower part, a resistance ring being arranged between said upper part and said lower part, a first contact area being provided on said inner side of said upper part, a second contact area being provided internally in the lower part, the switching mechanism producing, in temperature-dependent fashion, an electrically conductive connection between the first and second contact areas, said movable contact area interacting with said first contact area, the bimetallic snap-action disc lifting off the movable contact area from said first contact area depending on the temperature of said bimetallic snap-action disc, said resistance ring being arranged electrically in series with said current transfer element between said first and second contact areas when the switch is in its closed state.
