A tactile switch is a small electronic switch that opens or closes a circuit, usually by pressing a switch button. It is widely used in electronic equipment, household appliances, automobiles and other mechanical devices as an important component in control and operation.

What are the parts of a tactile switch?

1. Button
The button is the operable part of the tactile switch and is used for pressing or releasing operations. Keys are usually made of soft elastic material to provide good feel and reliable operation.

2. Spring
The spring is located under the key and provides rebound force when the button is pressed. It ensures that the key returns to its original position after release and makes the tactile switch reusable.

Contacts are an important part of the touch switch and are responsible for switching the connection and disconnection of the circuit.

Tactile switches usually have two contacts: Normally Closed and Normally Open.

(2) After releasing the button
The contacts return to their original state.
