What are rocker switches?

A rocker switch is an electrical component which opens or closes electrical circuits by using a rocking action, as one side is pressed, the other side rises. These switches are usually marked with a small circle on one end to designate that the device it actuates is “on” and a horizontal line or dash at the other to designate that the device is “off”.
