Some parameters and characteristics of touch switch need us to give you a detailed introduction. Specific details we will give you a detailed introduction below.
This paper will focus on the knowledge points of touch switch. It will explain the structure types of touch switch, and analyze the parameters and performance of side-press touch switch.
Firstly, the related contents about the structure types of light touch switch are introduced.
There are many kinds of light touch button switch structure, which can be divided into ordinary button-pressing, mushroom head type, self-locking type, self-resetting type, rotary handle type, with indicator light type, with lamp symbol type and key type, etc. There are single button, double button, three buttons and different combination forms, generally using building block structure, with button cap, reset spring, bridge type touch. Composition of head and shell, usually made into a composite, with a pair of normally closed contacts and often open contacts, some products can increase the number of contacts through a series of components. There is also a self-supporting button, which can automatically keep the closed position after pressing, and can only be opened after power failure. Light touch switch can complete the basic control of start, stop, forward and reverse, speed change and interlock. Usually each button switch has two pairs of contacts. Each pair of contacts consists of a constant open contact and a constant closed contact. When the button is pressed, two pairs of contacts act at the same time, and the contacts are usually closed, and the contacts are often opened and closed. In order to mark the function of each button and avoid misoperation, the button cap is usually made into different colors to show the difference. The colors are red, green, black, yellow, blue, white and so on. For example, red means stop button, green means start button, etc. When you press the first button, the button is pressed and the circuit turns on. When you press the button again, it bounces up and the circuit disconnects.
