Class Information
Number: 337/333
Name: Electricity: electrothermally or thermally actuated switches > Thermally actuated switches > With bimetallic element
Description: Subject matter including at least one thermal responsive composite element consisting of two different metals, bonded together, and having different coefficients of expansion, such that when heated, a bending motion of the composite element results. The resultant motion is utilized either directly or through an intermediate mechanical means to control the opening and/or closing of an electrical circuit.
