Claims (6)

  One end of a cylindrical material that is flexible and reversibly extends to a normal state is fixed to a base material, and a flexible bar is inserted into the cylindrical body, and the cylindrical body of the axis of the bar Is supported by a guide that maintains the state of the cylindrical member regardless of the state of the cylindrical member, one end of the rod member is fixed to the end of the cylindrical member that is not fixed to the base material, and the other end is protruded from the cylindrical member. The base member is provided with a surrounding portion that surrounds the end portion of the rod member protruding from the cylindrical member in a non-contact manner, and the surrounding portion of the end portion protruding from the cylindrical member of the rod member is provided in the surrounding portion. An on / off switch characterized by comprising conversion means for converting a motion with respect to an electrical signal into a binary value and outputting it.   2. The on / off switch according to claim 1, wherein the conversion means includes a light emitting element and a light receiving element, and converts the electric signal into binary using the presence or absence of light reaching the light receiving element from the light emitting element.   The light-emitting element and the light-receiving element are arranged in a positional relationship such that an optical path from the light-emitting element to the light-receiving element intersects with a movement path of the end portion of the bar member protruding from the cylindrical body. ON / OFF switch as described in.   The light emitting element and the light receiving element are arranged in a positional relationship in which light from the light emitting element is reflected by the end face of the end portion protruding from the cylindrical body of the bar at a predetermined position and reaches the light receiving element. The on / off switch according to claim 2.   The end portion of the bar member protruding from the cylindrical body includes a magnetically permeable member attached to the bar member, and the conversion means is connected to the coil and the coil that normally surrounds the magnetically permeable member. The on / off switch according to claim 1, further comprising an oscillation circuit, wherein the electrical signal is converted into a binary value using the strength of the induced electromotive force.   The end portion of the rod projecting from the cylindrical body includes a magnetic body attached to the rod, and the converting means includes a magnetic sensor, and uses the strength of the magnetic force detected by the magnetic sensor. The on / off switch according to claim 1, wherein the on / off switch converts the signal into a binary electric signal.
