Dual-output linear automatic sliding switch

Abstract

Disclosed is a dual-output linear automatic sliding switch. Based on two groups of different types of static contacts, gears are divided into a single number group and an even number group; two groups of the static contacts are alternately arranged, and the positions of the static contacts are matched with those of two groups of moving contacts on a moving contact base respectively; through alternate contact, alternately-changed gear signals with gears of 12, 23 and 34 are formed on outgoing lines of the two moving contacts at the same time; a larger interval space between the static contacts is allowed to be reserved, so that a phenomenon of electric leakage generated when the moving contacts move between the two static contacts can be reduced; and compared with a conventional sliding gear switch, the dual-output linear automatic sliding switch is higher in reliability.

Description

technical field [0001] The invention relates to a multi-gear switch, in particular to a double-output sliding switch. Background technique [0002] Linear gear switch and rotary gear switch are two commonly used gear switch structures, and the linear gear switch is also called a slide switch. It pushes the button handle equipped with the movable contact to slide through the movement mechanism, so that the movable contact piece is connected from one set of static contact pieces to another set of static contact pieces to realize circuit switching. [0003] Most of the gear selection switches used in the traditional power sector are rotary switches, which work under high current conditions and have a large volume. It is usually a cylindrical structure. In order to avoid leakage between the static contacts in the switch, a large amount of insulating oil needs to be poured into the switch, so the rotation resistance is relatively large and the switching speed is slow.

AI Technical Summary

Problems solved by technology

[0004] The distance between the static contacts is small, when the moving contact is between two static contacts, easy leakage is the problem of this type of switch

In order to solve the above problems, the distance between the static contacts has to be increased to reduce the leakage phenomenon when there are moving contacts between the static contacts. This will undoubtedly greatly increase the distance between the static contacts. The distance between the gears leads to a great increase in the length of the entire gear switch, which seriously increases the volume of the gear switch
