Class Information
Number: 337/365
Name: Electricity: electrothermally or thermally actuated switches > Thermally actuated switches > With bimetallic element > Bimetallic element unitary with or directly actuates contacts > Snap-action
Description: Subject matter wherein the claimed structure includes means whereby the movable contact, or contacts, may be operated from a first position to a second position quickly, as by a snap action with the contact motion being independent of the rate of movement of the operator. This may be accomplished by means of a spring, a permanent magnet, or other appropriate means, such as for example; an inherent characteristic or structure of the bimetallic element itself.
