Button switch with socket and control method

Abstract

The invention provides a button switch with a socket and a control method. The button switch comprises a push rod. One end of the push rod protrudes to form a first push rod connecting part and a second push rod connecting part, and movable contact member springs are embedded respectively. Each movable contact member spring abuts against a movable contact member, and first contacts are arranged ontwo ends of the movable contact member. A base connecting part is formed on a base. The first push rod connecting part and the second push rod connecting part can be installed on the base connectingpart. At least one stop post corresponding to a stop block is formed on the base. A number of insertion holes corresponding to the first contacts are formed in the base. Second contacts are arranged on one end of two first static contact members. Second contacts are corresponding to the first contacts on two ends of the movable contact member in a first mounting part. Third contacts are arranged on one end of two second static contact members, and are corresponding to the first contacts on two ends of the movable contact member in a second mounting part. According to the invention, the structures of 'one normally open contact and one normally closed contact ', 'two normally open contacts' or 'two normally closed contacts' can be freely selected and set, and the use scope is expanded.

Description

technical field [0001] The invention relates to an electric control device, in particular to a button switch with a socket and a control method. Background technique [0002] The contact combination of traditional products is relatively simple. There are only one normally open and one normally closed contact or only two normally open contacts, which cannot realize the structure of free combination, and users will have limitations in the use process. The movable contacts of traditional products use tension springs to hook the shrapnel of the moving contact body, which has the following advantages: 1. Difficult assembly, limited output per capita, and high cost; 2. The life of the tension spring determines the life of the product, and the life of the tension spring is generally relatively short , leading to a very short service life of traditional products; 3. In the process of controlling high-load lines, the contacts of traditional products will be bonded due to insufficient...

Problems solved by technology

[0002] The contact combination of traditional products is relatively single. There are only one normally open and one normally closed contact or only two normally open contacts, which cannot realize the structure of free combination, and users will have limitations in the use process

The movable contacts of traditional products use tension springs to hook the shrapnel of the moving contact body, which has the following advantages: 1. Difficult assembly, limited output per capita, and high cost; 2. The life of the tension spring determines the life of the product, and the life of the tension spring is generally relatively short , leading to a very short service life of traditional products; 3. In the process of controlling high-load lines, the contacts of traditional products will be bonded due to insufficient tension of the tension springs, and products with tension spring structures cannot guarantee the life of the product. Defects such as circuits that control high loads under

The self-locking hook of traditional products uses a single-sided hook, and the push rod is also one-sided, which cannot be balanced. Once the product is misplaced during assembly, the self-locking function will fail

The indicator lights of traditional products need to weld the drop-down resistor to the LED light-emitting diode first, then install it inside the product, then distort the position of the drop-down resistor, and then weld the drop-down resistor to the pin workpiece inside the product, the entire installation The welding process is very complicated, and the welding is carried out inside the product, resulting in low product reliability and easy false welding, resulting in a high failure rate of the product

There is no adapter socket for traditional products. Users need to weld the wire harness on the product by themselves during use. The use process is cumbersome, and the welded products are not easy to replace and maintain.
