Casing for a temperature-dependent switch and sealed switching device

A casing for receiving, in a hermetically sealed manner, a temperature-dependent switch that is configured to switch in a temperature-dependent manner between a closed state, in which the switch establishes an electrically conductive connection between a first external terminal and a second external terminal, and an open state, in which the switch disconnects the electrically conductive connection, wherein the casing comprises:

• a first metal casing part;
• a second metal casing part which is fixed to the first metal casing part by a hermetically sealing, electrically insulating connection;
• and
• a third electrically insulating casing part arranged between the first metal casing part and the second metal casing part;
• wherein the first metal casing part and the second metal casing part together form a receptacle that is configured to receive the temperature-dependent switch such that, when inserted into the receptacle, the temperature-dependent switch is electrically connected to the first metal casing part by its first external terminal and electrically connected to the second metal casing part by its second external terminal.
