Abstract
A push switch, having a conductive member which includes three integrally formed components: a conductive element, a U-shaped clip, and a conductive cantilever element. An overheating destructive element is provided on the conductive cantilever element, and the overheating destructive element can be destroyed at a destructive temperature, in which the destructive temperature is between 100° C. to 250° C. The push switch has a contact element in contact with the overheating destructive element so as to control the conductive cantilever element to be electrically connected or disconnected. When the conductive cantilever element is electrically connected, and if the overheating destructive element is overheated and destroyed, the conductive cantilever element is driven to become electrically disconnected, thereby achieving protection against overheating. The integral formation and manufacturing of the conductive member has the advantages of being structurally simple and easy to assemble.
