Abstract
A switch module with a built-in structure of anti-surge and dual disconnection mainly comprises an overcurrent protection switch having plates and insulating elements for anti-surge and dual disconnection structure ingeniously built inside a heat-resisting housing. The switch module has a first connecting point and a second connecting point for operation. When overvoltage occurs, temperature of at least one metal oxide varistor would instantly rise up to a degree higher than the melting point thereof, melting at least one thermo-sensitive piece, loosening at least one spring element, displacing a pushing element and thus forcing the connecting points detaching from each other to turn off the switch and stop supplying electricity power; meanwhile, insulating elements would isolate conductive components such as thermo-sensitive pieces, spring elements and plates to further ensure a complete disconnection and more of electricity safety.
