Class Information
Number: 335/167
Name: Electricity: magnetically operated switches, magnets, and electromagnets > Electromagnetically actuated switches > Latching means
Description: Subject matter wherein the structure includes specific details of operating means whereby at least one set of contacts may be restrained in one of two normal conditions (open or closed). The latching means usually consists of structure adapted for mechanically maintaining a contact actuating means, such as a toggle arrangement, armature or other carrier, in a given position independently of the magnetic control means so that once the contacts are closed, or opened, the magnetizing current may be cut off and the contacts remain in their opened or closed condition until a tripping action takes place.
