This switch has a self lock mechanism. This push button switch is a small, sealed mechanism that completes an electric circuit when you press on it. When it's on, a small metal spring inside makes contact with two wires, allowing electricity to flow. When it's off, the spring retracts, contact is interrupted, and the current won't flow. The body of the switch is made of non-conducting plastic.
