Abstract
The utility model provides a quick-response over-voltage protection switch device. The quick-response over-voltage protection switch device comprises a main body, a base, an elastic disc, a sliding support assembly and at least one group of contact assemblies, the base is arranged at one end of the main body, and a channel is formed in the base; the elastic disc is clamped between the base and the main body and covers the corresponding end of the channel in a sealing manner; the sliding supporting assembly is clamped in the body in a sliding mode, one end of the sliding supporting assembly abuts against the elastic disc, and an elastic assembly is arranged between the other end of the sliding supporting assembly and the inner wall of the body. The contact assembly comprises a static contact and a movable contact, the static contact is fixed in the main body, the movable contact is fixed on the sliding support assembly and corresponds to the static contact, and the movable contact and the static contact can be connected / disconnected when the sliding support assembly slides back and forth in the main body. The high-temperature protection circuit is high in response speed and long in service life during use, and can be used for high-temperature protection.
