Class Information
Number: 337/134
Name: Electricity: electrothermally or thermally actuated switches > Electrothermally actuated switches > With longitudinally expansible solid element (e.g., rod, wire strip, etc.) > With manual or other mechanical contact actuating means > Snap-action (e.g., bistable) > With magnetic biasing or holding means
Description: Subject matter including means whereby a field of magnetic flux is set up in the vicinity of the main contacts. The force exerted by the magnetic flux field is utilized either to detract from or add to the force exerted by a mechanical actuating means resulting in a rapid movement of the contacts upon the magnetic force or the spring force being overcome one by the other.
