A sliding rod type travel changeover switch

Abstract

The invention relates to a switching device for a current direction, especially to a stroke switch that employs a structure with a slide bar type and enables the current direction to be converted bidirectionally. According to a widely-known stroke switch at present, there are defects including signal function and weak adaptability and the like; however, an objective of the invention is to overcome the above-mentioned defects so as to provide a unique control device for a stroke position. The stroke conversion switch is composed of eighteen parts including a pedestal, hole sinking caps, a pedestal cushion block, a positioning top button, a positioning nut, and a top boot and the like and three modules that include a pedestal module, a slide bar module, and a circuit module are formed. According to the invention, the stroke conversion switch enables a mechanical shift of a moving object to be converted into an electrical signal, wherein the widely-known stroke switch also has such a conversion function; in addition to the above-mentioned conversion, the stroke conversion switch also has advantages of bidirectional on-off power supply, current direction switching, accurate stroke distance arrangement, and automatic procedure arrangement and the like. In addition, the switch has characteristics of simple implementation and simple manufacture; and a product that is manufactured is solid and durable as well as can be used conveniently; therefore, the stroke conversion switch has broad market space and high economic value added.

Description

technical field [0001] The invention relates to a current direction switching device, in particular to a travel switch which adopts a slide bar structure and bidirectionally switches the current direction. [0002] Background technique [0003] Travel switch is a kind of position switch (also known as limit switch), and it is a commonly used small current master electrical appliance. It uses the collision or approach of the moving object to make the contact of the travel switch act, so as to achieve the purpose of connecting or breaking the circuit and controlling the movement of the electric object. Usually, the limit switch is used to limit the movement position or movement stroke of the electric object, so that the moving object will automatically stop, reverse movement, variable speed movement or automatic reciprocating displacement according to a certain position or stroke. [0004] The main function of the limit switch is to convert the mechanical displacement of the...
