Class Information
Number: 335/192
Name: Electricity: magnetically operated switches, magnets, and electromagnets > Electromagnetically actuated switches > Contact-actuating means > With biasing means (open or closed)
Description: Subject matter wherein the significant contact actuating structure includes spring biasing means whereby the movable contact or contacts are positively biased toward one of two positions independently of the armature means. The biasing may be toward either the open or closed position and is operative to assist an armature or other actuating means in the opening or closing operation.
