  • Patent number: 10446300
    Abstract: An anti-surge structure built in switches includes three metal-oxide varistors disposed in an insulating body in stair-like arrangement. The metal-oxide varistors further has an insulating band surrounding a middle metal-oxide varistor and defining four isolated insulating areas within the insulating body, so as to avoid high voltage flashover and to protect the structure from external impacts. With the stair-like arrangement, each metal-oxide varistor has a connecting area for both ends of a metal strap to be welded thereon by low-temperature solder paste. When the low-temperature solder paste are melted by heat, a compressed spring element thereof is ejected to displace a pushing element thereof and to further detach two connecting points of the structure, so as to break a circuit connected by the structure.
