A switch includes a body with a switch member and two springs are connected to an underside of the switch member. Two identical circuit assemblies are isolated from each other and received in the body. Each circuit assembly has two terminals and a bimetallic plate has a first end connected to the first terminal and the bi-metallic plate can be deformed when the switch is overloaded to separate two contact points to cut off the circuit. A carry member is connected to the two respective bi-metallic plates of the two circuit assemblies so that when either one of the two bi-metallic plates is deformed, the carry member is moved to separate the two contact points of the other circuit assembly and cut off the two circuit assemblies simultaneously when the switch is overloaded.
