Two terminals are disposed within the body, wherein the first terminal forms a bimetal thereon. The terminals are electrically connected with each other in a normal state. A linkage is mounted on an end of the lever, which forms an isolated member on the lower end of the linkage. Pressing the lever, the isolated member of the linkage will moved upwards to separate the two terminals. When the lever is held by some heavy substances, the bimetal can be deformed to disconnect with the second terminal in over-current for cutting out the circuit.Field of SearchWith reclosing or reset meansWith push-button actuating means Performs dual functions (e.g., main contact) With contact pressure maintaining or adjusting means With signal or indicating means Toggle With bimetallic elements (i.e., motion takes place in a plane at right angles to its major axis) With manual or other mechanical contact controlling means Bimetallic element unitary with or directly actuates movable contact means With bimetallic element Snap-action With toggle linkage Bimetallic element unitary with or directly actuates contacts With reset means Illuminated Light visible through actuator | |
