Switches capable of suppressing arcs

Abstract

A switch capable of arc suppression comprises a switch button, a warped plate assembly, a wire inlet terminal, a driving element subassembly, a warped plate positioning element and a static contact, wherein the warped plate comprises a warped plate body, the middle of the warped plate body is of a U shape, the driving element subassembly comprises a driving rod, a spring and a transition element, the upper end of the transition element is connected with the switch button, a cylindrical accommodating recessed cavity is arranged on the transition element, the upper end of the driving rod is arranged in the accommodating recessed cavity, the upper end of the spring props against the bottom of the accommodating recessed cavity, the lower end of the spring props against the driving rod, and the end part of the lower end of the driving rod props against the bottom of the U shape at the middle of the warped plate body. During switch connection or disconnection process, the driving element subassembly can be contacted and connected with the side wall of a movable contact which is far away from the U shape at the middle of the warped plate body and is in contact with the static contact, thus, jumping between the warped plate body and the upper end of the ire inlet terminal and between the movable contact and the static contact can be prevented or reduced greatly, switching arc can be greatly reduced, and the service life of the switch is prolonged.

Description

technical field [0001] The invention relates to an electrical device, in particular to a switch capable of suppressing electric arcs. Background technique [0002] A switch is a common electrical device used to make or break current in one or more circuits. A commonly used switch includes a switch button, a rocker assembly, an incoming line terminal, a driver assembly, a rocker positioning member, and a static contact. Wherein the seesaw assembly includes a seesaw body, the middle part of the seesaw body is U-shaped, and the two side walls of the U-shape in the middle part of the seesaw body are respectively folded outwards to form a seesaw fold, and the seesaw fold is fixed with a moving contact; The lower surface of the middle part of the seesaw body is supported on the upper end of the incoming line terminal, and the front and rear ends of the middle part of the seesaw body are provided with positioning protrusions; The drive assembly includes the drive rod, spring and ...

AI Technical Summary

Problems solved by technology

The existing problems are: [1] Grease has the negative effect of strengthening the arc. If the amount is not accurate, the degree of ablation of the rocker body will increase, which will reduce the life of the switch and cause accidents; [2] Solid grease hardens at low temperature, hindering the The normal activity of the switch rocker assembly makes the switch unable to be turned on normally, and also affects the feel of the switch; [3] Oiling will increase labor costs, material costs, production equipment costs and other production costs
