Abstract
A foot switch comprising a base covered with an upper cover to hold a pressure-contact switch, a rotary type actuating member, a compression spring and a press member. The press member is supported by the compression spring to protrude beyond the center hole of the upper cover. Once the press member is pressed down, the pressure-contact switch is electrically connected by the operation of the acutating member, and the press member is forced by the compression spring to move back to original position after release of pressure force therefrom. Once the press member is pressed down again, the pressure-contact switch is electrically disconnected.
