Definition

This class is restricted to the structure of electric current switching devices of general application for closing or opening electrical circuits which devices depend upon the heating effect of a current or of the ambient temperature of the surrounding medium for their operation.

This class also includes miscellaneous elements, or subcombinations of elements, restricted for use in and with the class type switches and which have not reached the status of separate classification elsewhere.

This class also includes implements or handling devices specifically adapted for use with the class type switches and not provided for elsewhere in a separate class.

Electrical systems or circuits which include electrothermally or thermally operated switches, comprising the subject matter of this class, are excluded from this class. These systems or circuits are classified in the various electrical or art classes depending upon the type of system or apparatus controlled.
