A foot switch is provided to enhance user convenience by adjusting a relative position between a bottom plate and a switch element according to a body size of a user. A foot switch includes a base(12), a bottom plate(14), and a heel cup(16). The bottom plate is mounted on the base. The heel cup is arranged on the bottom plate, such that a length of the bottom plate is increased or decreased. Plural locking pins, which are mounted on the heel cup, prevent the heel cup from sliding. The locking pins are assembled into a locking hole of the bottom plate. A position of the heel cup is visually displayed by an indicator. The bottom plate includes an elevation reference point, which is used for aligning a foot with a center of the bottom plate.
