Abstract
A temperature-dependent switch has a temperature-dependent switching mechanism and a housing, receiving the switching mechanism, that has a lower part and an upper part made of insulating material. On the inner side of the upper part there are two stationary contacts, each of which is connected to an external terminal associated with it. A current transfer member is moved by the switching mechanism, which electrically connects the two stationary contacts to one another as a function of temperature. A cavity, into which project two contact surfaces which are each connected to one of the stationary contacts, is located in the upper part.

A temperature-dependent switch, comprising:
- a temperature-dependent switching mechanism,
- a housing for containing said temperature-dependent switching mechanism, said housing including a lower part and an upper part, said upper part made of insulating material and having an inner side and an outer side,
- two stationary contacts provided on the inner side of said upper part, each stationary contact being connected to an associated external terminal and having a contact surface on said inner side of said upper part, and
- a current transfer member moved by said temperature-dependent switching mechanism to electrically connect said two stationary contacts to one another in dependence of the temperature of said temperature-dependent switching mechanism,
- a cavity being provided in said upper part and open to the outer side of the upper part, both of said contact surfaces projecting into said cavity so as to expose said two contact surfaces to the outer side of said upper part.
