Abstract
A temperature-dependent switch (10) to close or open an electric circuit depending on the temperature of a bimetallic part (26) comprises an electrically conductive housing (12) with an underside (13). An electrically conductive cover (16) is provided to close the housing (12). There is an insulating disk (17) between the housing (12) and the cover (16) which electrically isolates the housing (12) from the cover (16). The housing (12) contains a switching device (15) which makes or breaks an electric contact between the housing (12) and the cover (16) depending on the temperature of the bimetallic part (26), whereby the electric circuit can be connected on the one hand to the cover (16) and on the other to the housing (12). The housing (12) is provided with a collar (35) inset into the underside (13), such that a strand can be connected to the collar (35) without affecting the overall height of the switch (10)
