Class Information
Number: 335/170
Name: Electricity: magnetically operated switches, magnets, and electromagnets > Electromagnetically actuated switches > Latching means > Magnetically operated
Description: Subject matter wherein the latching structure includes independent magnetic means; such as a holding coil and armature, for instance, whereby the latch is operated into, or held in holding relationship with contact actuating means. Also included in this subclass are devices where no mechanical latch is used and which depend entirely upon magnetic means for directly holding the contact arm or arms in closed position.
