Problems solved by technology

However, in the prior art, when assembling these elements into contact switches, more other parts are needed, and the structure is more complicated, and the installation is inconvenient
Another point is that it is too sensitive (a slight change in the equipment will cause the switch to be disconnected or turned on), and it cannot be used in situations where the environment is harsh and there is a certain travel requirement for the switch contacts.

Abstract

The invention relates to a rectangular contact switch, which includes a shell, an insulator, a push rod and a U-shaped conductor. The ejector rod is set in the middle through hole of the insulator II, and the through holes on both sides of the insulator II are set with cap holes, the U-shaped conductor is set in the rectangular groove of the insulator I, and the guide plate and the rectangular groove groove of the insulator I A spring is arranged between the bottoms, and two guide posts are respectively inserted into the through holes on both sides of the insulator II, one end of the ejector rod is fixedly connected with the guide plate of the U-shaped conductor through an insulating pad, and the other end of the ejector rod extends out of the end cover to set . The rectangular contact switch of the present invention has simple structure and reliable performance, and can realize various trigger functions of the switch by controlling the pressing distance of the ejector rod, and can make up for the shortcoming of the general contact switch, and realize the bluntness of the switch. function.

Description

technical field [0001] The invention relates to the technical field of contact switches, in particular to a rectangular contact switch. Background technique [0002] Contact switch refers to a switch that uses the contact and separation of moving and static contacts to interrupt or connect the circuit. Contact switches generally include key components such as static contacts, moving contacts, operating push rods and springs. However, in the prior art, when assembling these elements into a contact switch, many other parts are needed, and the structure is relatively complicated, and installation is inconvenient. Another point is that it is too sensitive (a slight change in the equipment will cause the switch to be disconnected or turned on), and it cannot be used in harsh environments and places with certain travel requirements for the switch contacts. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the above technica...
