🔝 What is the push button switch?

Push button switch means to push the drive structure with buttons, making the moving contact and the static contact to press on or off, which can realize the circuit switching.

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.

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 into different colors in order to show the difference. It has the color of red, green, black, yellow, blue, white, etc. For example, red means stop button, green means start button and so on.

The following is a brief introduction of several button types:

1. Momentary push button switch A push button switch causes a temporary change in an electrical circuit only while the switch is physically pushed. A spring returns the switch to its original position immediately afterwards.
2. Latch push button switch A latching push button function also referred to as maintained, means that it remains in a position until pressed again. It required to be pressed down or touched multiple times to either turn on or off the device or function.
3. Metal push button switch A metal button switch is a button made of metal. The shell of a metal button switch can generally be made of three materials: brass, stainless steel and zinc alloy.
4. waterproof push button switch The waterproof push button switch is suitable for use in water splashing or outdoor environments. The waterproof button can avoid accidents.
5. led push button switch Led push button switch is a button with built-in LED lamp beads, which can light up the LED when the power is on. Now it can produce double color and tricolor button switches.
6. car push button switch The car push button switch can engrave any symbol you want, and it can look more beautiful when installed on the car.
7. emergency stop button switch The emergency stop button can also be called the “emergency stop button”, that is, when an emergency occurs, people can quickly press this button to achieve protection.
