PROBLEM TO BE SOLVED: To provide a security display system unit, which comprises a light emitting switch unit and is constructed so that the security set state can be confirmed externally with the naked eye, and to provide a security display method. SOLUTION: The security display system unit is characterized in that the security display system unit comprises light emitting switch units (7A, 7B, 7C, ...) comprising two sets of light emitting diodes 7Ab, 7Ac and diodes 7Ad, 7Ae, a light emitting diode 7Ab is connected in series to a diode 7Ad while a light emitting diode 7Ac is connected in series to a diode 7Ae, the two assemblies are connected to each other in an opposite direction to constitute the light emitting switch units (7A, 7B, 7C, ...), the security display system unit is constructed so that the security set state can be confirmed with the naked eye, the light emitting switch units have a light emitting part that performs LED light emission, and the light emitting switch units can be connected to each other and are constructed with a reception control unit AP1 loaded with a constant current driving circuit for supplying an electric power to the light emitting switch units.
