Push Button Switch
A push button switch is an electrical switch that is triggered by pressing a button. It’s commonly used to control devices such as lamps, doorbells, and alarms.
They can be momentary (where the switch returns to its original position when released) or maintained (where the switch stays in the activated position until it’s manually reset). Push button switches come in various sizes, shapes, and configurations, and can be found in a wide range of applications, both residential and industrial.
Filn switches can be divided into many types by function, such as momentary push button switch, latch push button switch, metal push button switch, waterproof push button switch, LED push button switch, car push button switch, emergency stop button switch, etc.
What is the push button switch?
The push button switch has a simple structure and is widely used in master control electrical appliances. In an electrical automatic control circuit, manually emit control signals to control contactors, relays, electromagnetic starters, etc.
The push button switch can complete the basic control of start, stop, positive and negative rotation, speed change, interlock and so on.
Usually, each push button switch has two pairs of contact, each pair of contact is made of a normally open contact and a normally closed contact. When the button is pressed, the two pairs of contacts act simultaneously, the normally closed contact is disconnected and the normally closed contact is closed.
Specify the function of each button to prevent mis-operation. The button cap is usually made in different colors in order to show the difference. It has red, green, black, yellow, blue, white and other colors. For example, red means stop button, green means start button and so on.
The following is a brief introduction to several button types:
|Push button switches type||Explain the meaning|
