A mini momentary contact switch, also known as a micro switch, is an electrical switch that is activated by very little physical force. Micro switches are widely used in many applications, such as in devices, machines, industrial controls, and vehicles, for controlling electrical circuits. They are typically designed to switch current only in control circuits, although some switches can be used directly to control small motors, solenoids, lamps, or other devices.

This is a small micro switch sensor designed for Arduino. It can be directly connected to the IO Expansion shield board. It incorporates the pull-up resistor and the LED status indicator on the board, making the testing process easier. The roller mini switch makes this device suitable for various applications in different environments.
