Background

A circuit switch is an electronic component that can open a circuit, interrupt a current, or cause a current to flow to another circuit. The most common switches are electromechanical devices operated by a person, in which there are one or several electrical contacts. The "closed" of a contact means that the electronic contact is conductive, allowing current to flow; an "open" of the switch indicates that the electrical contact is not conductive, creating an open circuit, and not allowing current to flow.

Button-type rocker switches are widely used in life switches of people, but the conventional button-type rocker switches have several major disadvantages: 1) when the rocker button is opened and closed, the distance of the clearance between the upper and lower parts of the rocker button is larger, so that the noise generated during the opening and closing action is relatively increased; 2) when the traditional button rocker switch with the socket is used, the limitation is often caused by the action distance of the switch rocker button, and when a plug is plugged in, the rocker button is often limited in space and inconvenient to move; 3) traditional button type rocker switches protrude out of the wall surface and are not attractive.
