Abstract: A wireless foot switch according to one embodiment includes a battery unit, a switch unit, a controller, and a state switcher. The battery unit supplies power. The switch unit provides input to an X-ray diagnosis apparatus. The controller transmits by radio, to X-ray diagnosis apparatus, information input by the switch unit. Based on an external signal from the outside of the X-ray diagnosis apparatus, the state switcher causes the controller to transition from a resting state to an operational state.
