DEFINITION

Classification: 337/411

(under subclass 402) Subject matter including significant details of means whereby the main switch contacts are latched, positively held or otherwise retained either in an operative or inoperative position. The latching means usually consists of mechanical means capable of being tripped or released upon operation of the thermal fuse.

(1) Note. For other latch, trip, or holding means used in

devices of this class, see the subclasses listed under subclass 46.
