Switches

What are Switches?

Switches are mechanical components that control the flow of current in a circuit by physically opening or closing a conductive path when pressed, toggled, or triggered. Different switch types use different mechanisms — a tactile switch uses a spring-loaded dome, a micro switch uses a lever actuator, and a rotary switch uses a rotating contact. A common example in Indian college robotics builds is using a lever type micro switch as a limit switch to automatically stop a motor when the robot arm reaches its maximum travel position.

How to Choose the Right Switches

Choose based on the type of user interaction and mounting requirement your project needs. For breadboard-based Arduino builds, a standard 6x6mm tactile switch fits directly into standard tie points. For detecting mechanical end positions in robotics, a lever type micro switch is the correct choice as it triggers reliably under physical contact. For panel-mounted power controls, a rocker switch or slide mini switch provides a clean on off button switch interface. One practical tip: always specify the switch button actuator height when ordering for enclosure panel mounting, as a mismatched height leaves the button too recessed or protruding too far through the panel cutout.
