A button switch and a control method thereof

Abstract

The invention provides a push button switch and a control method thereof. A push rod, one end of which protrudes to form a second connecting part, wherein the second connecting part can be fitted withthe first connecting part, and a through receiving cavity is formed on the push rod; A movable contact spring which can be accommodated in the accommodating cavity; A movable contact inserted in theaccommodating cavity, the two ends of the movable contact are respectively provided with movable contacts, and the spring of the movable contact is pressed against the movable contact; A base housing,wherein the push rod can be accommodated in the interior of the base housing; A push rod spring clamped between the bottom of the push rod and the closed end of the base housing; A stationary contacthas a stationary contact at one end, and the stationary contact corresponds to a moving contact. The invention freely sets the movable contact to a normally open or normally closed structure according to actual needs, and achieves the purpose of expanding the use range of users by setting the movable contact at different positions, above or below the spring of the movable contact, and setting therelative positions of the static contact and the movable contact.

Description

technical field [0001] The invention belongs to an electric control switch, in particular to a button switch and a control method thereof. Background technique [0002] The contact combination of traditional products is relatively single, with only one normally open function, and the structure of free combination cannot be realized, and users will have limitations in the use process. The movable contact of the traditional product uses a tension spring to hook the shrapnel of the movable contact body. First, the assembly is difficult, the output per capita is limited, and the cost is high. 2. The life of the extension spring determines the life of the product. The life of the extension spring is generally relatively short, resulting in a very short service life of traditional products. 3. Products with extension spring structure cannot control high-load circuits under the premise of guaranteeing life. Traditional products do not have built-in waterproof rubber parts, which ...

AI Technical Summary

Problems solved by technology

[0002] The contact combination of traditional products is relatively single, with only one normally open function, and the structure of free combination cannot be realized, and users will have limitations in the use process

The movable contacts of traditional products use tension springs to hook the shrapnel of the movable contact body. First, assembly is difficult, per capita output is limited, and the cost is high

2. The life of the extension spring determines the life of the product. The life of the extension spring is generally relatively short, resulting in a very short service life of traditional products.

3. Products with extension spring structure cannot control high-load circuits under the premise of guaranteeing life

Traditional products do not have built-in waterproof rubber parts, which cannot improve the protection level of the product

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

Traditional products only have single-color lights, and cannot realize the function of two-color lights

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.
