◆ The Working Principles Of Push Buttons’ Contacts 

The contacts of push buttons are divided into normally open contact and normally closed contact. When the button is pressed, the normally open contact is closed and the normally closed contact is disconnected. After the hand is released, the normally open contact is restored while the normally closed contact is restored and closed.

◆ How Does A Push Button Work?

The push button, a master device commonly used in the control loop, is a kind of control element that is operated manually and has a spring that can be automatically reset after operation. In the process of the subsequently continuous development and evolution, various kinds of specification products with the functions of indicator lights, keyholes, emergency braking are added, but their essential structures and working principles are not changed.
