A non-conductive plate extends laterally from the button. A first terminal plate and a second terminal plate respectively extend from the casing. A first contact point extends from a side of the second terminal plate. A bimetal plate is connected to the first terminal plate and has two legs extending therefrom. A conductive member is connected between the two legs and connected to the second terminal plate when the button is pushed. The non-conductive plate is located between the conductive member and the second terminal plate when the button jumps up and the two legs are deformed away from the second terminal plate.Field of SearchWith push-button actuating meansWith direct contact separating means (e.g., plunger camming means) With reset means With bimetallic element With manual or other mechanical contact control means With toggle linkage Bimetallic element structure or composition of material Snap-action Toggle Trip-free Bimetallic element unitary with or comprising latch means Performs dual functions (e.g., main contact) With signal or indicating means With manual or other mechanical contact controlling means Independently operative bimetallic elements Bimetallic element unitary with or directly actuates movable contact means Housing, casing or support means With external circuit connection means Wire or other stranded element Rocking actuator (e.g., rocker, lever) Knife blade contact With catch Housing and actuator form detent Actuator biasing mechanism | |
