How pushbutton switches work

Share This Post

A push button switch is a switch that uses a push button to push the machine transmission mechanism to connect or disconnect the moving contact and the static contact, and then switch the circuit through this. We all know that the button switch is a switch controller with a relatively simple structure but a wide range of applications. The button switch can complete a series of basic switch control, such as start, stop, forward and reverse rotation, speed change and so on. Why can the button switch complete these controls under a relatively simple structure? This requires a series of analysis from some principles of the button switch.

There are generally many kinds of button switches with different structures, which are divided into ordinary button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, type with indicator light, type with lamp symbol and key type, etc. Although the structure is different, their working principle is basically the same. There are single-button, double-button, three-button and different combinations of button switches. If we want to understand its working principle, we must first know the structure of the button switch, and analyze its working principle from the structure.

Since most of the commonly used building block structures are used, we will use the above figure to understand the principles of some building block button switches. First of all, it has a button cap, so it can be called a button switch, which is the part that controls the entire button switch. Generally speaking, a button switch has two fixed contacts. These fixed contacts are divided into normally closed contacts and normally open contacts. We need to know that the normally closed contacts are disconnected first, while the normally open contacts are To be closed later, these two normally closed and normally open contacts are the changeover contacts of the entire push button switch and are the core part of the push button switch. Then we can see from the picture that there is also a movable contact and wiring in this button switch, which are indispensable accessories for the button switch.

Simply put, the working principle of this button switch is to manually press or pull out the button cap, so that it can operate along the bearing in the switch, press down or pull out the switch contact in the switch, and then The push button switch works fine.
