A foot switch is provided to improve productivity and reduce a cost of a product by reducing the number of components and improve the reliability of the product and rapidly cope with a safety accident by always pressing and rotating a pedal to operate a second switch unit. A switch main body(100) includes a switch receiving unit(120) to receive a first switch unit(2) and a second switch unit(6) on one side. A hinge axis(200) is rotatably installed on one side of the switch receiving unit in a horizontal direction. A pedal is positioned on the other side of the main body and stepped by a user's foot as one end thereof is fixed to the hinge axis to rotate the pedal upward and downward. A pressing member(400) presses switches(3,7) of the first and second switch units by being fixed to the hinge axis inside the switch receiving unit and being rotated as the pedal is stepped. A first coil spring elastically supports the pedal upward by being vertically installed between the pedal and the switch main body. A second coil spring is vertically installed inside the first coil spring and has a shorter length than that of the first coil spring. Spiral directions of the first and second coil springs are opposite to each other.
