Principle

Push-button switches usually have a building block structure. The structural features of push-button switches include button caps, return springs, static contacts, moving contacts, housings, and support rods. It is normally designed as composite push button switch with a pair of normally-open and normally-closed contacts.
When the button is not pressed, the moving contact is connected to the static one above, forming normally-closed contacts, while the moving contact is disconnected to the static one below, forming normally-open contacts; when the button is pressed, normally-closed contacts disconnect and normally-open ones connect. After releasing it, the push switch will return to the initial status under the action of the return spring.

Usage Description

The push button module can recognize button action and output digital signal. When the button pressed, it outputs high level, "On" or "1"; released, outputs low level, "off" or "0”.
