Temperature-dependent switch

A temperature-dependent switch, comprising:

• a temperature-dependent switching mechanism having a switching mechanism unit, which comprises a movable contact part coupled to a bimetallic snap-action disc, and having a switching mechanism housing, in which the switching mechanism unit is arranged and held captively therein, wherein the switching mechanism housing comprises an electrically conductive first base body;
• a switch housing having an electrically insulating second base body, in which the switching mechanism housing is arranged and held captively therein, wherein the switch housing comprises a stationary contact part, which acts as a mating contact to the movable contact part;
• a first connection contact part, which is electrically connected to the first base body;
• and
• a second connection contact part, which is electrically connected to the stationary contact part:
• wherein the first base body surrounds the switching mechanism unit from a first housing side, a second housing side opposite the first housing side, and a housing circumferential side extending between and transversely to the first and the second housing sides,
• wherein the first base body comprises on the first housing side an opening through which the movable contact part interacts with the stationary contact part, and wherein the second base body surrounds the first housing side and the circumferential housing side of the switching mechanism housing.
