Claim:
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, wherein the resistance ring comprises an upper ring area and a lower ring area, the current transfer element comprising a rim resting on the upper ring area, the lower ring area resting indirectly or directly on the second contact area, and wherein a spacer ring is arranged between said rim of said current transfer element and said upper part, said rim of said current transfer element being fixed between said spacer ring and said resistance ring.
