ABSTRACT:
A push button style power switch using a switching button to control movement of a curved sheet to form an electric power on or off state, the power switch is comprised of a base, a power control portion, a switching button and a cover. Wherein the power control portion is provided with a first conducting piece, a second conducting piece and a curved sheet. The conducting pieces connect respectively with two connecting ends of a wire of a power line. The curved sheet is mounted on the first conducting piece. When the switching button is pushed down, it lowers a bottom control tip beneath it to render the tailing end having a small boss of the curved sheet to move down/raise and press/leave the second conducting piece to make electric connection/circuit breaking of the power line. Therefore, this is a power switch structure capable of fast switching.
