A rocker switch is a device having a plurality of terminals and means operated by a rocker for making and breaking electrical connections between pairs of those terminals. A rocker switch includes a button that is mounted to a case to pivot about an axis. A spring is typically placed in contact with the button to exert a biasing force that will maintain the button in one or more of the stable positions. The plunger operates a rocker actuator by a force exerted from the spring. The spring also supplies the force that causes the switch to toggle from one stable position to another.

In general, the rocker switch is constructed such that its switch components or parts are housed in a square or rectangular housing the top of which is open and an operation button is mounted at the opening space of the box at the top thereof such that it can be moved for seesaw movement. The rocker switches are used in various kinds of OA machines, amusement and game machines, measurement instruments, and medical instruments.
