Two strip-shaped light emitting display portions 6 each made of an organic EL element are disposed on the left and right frame pieces one by one with the light emitting surface facing forward, and the anode of each light emitting display portion 6 A feeding electrode (not shown) electrically connected to the cathode and the cathode is disposed. In the present embodiment, the light-emitting display unit 6 is composed of six organic EL elements. However, the light-emitting display unit 6 is not intended to limit the number of organic EL elements to six. May be arranged one by one, or the light emitting display section 6 may be constituted by one organic EL element formed in a square shape.

  FIG. 6 shows an internal circuit diagram of the switch device A. The switch device A is input via the signal input unit 9 and a signal input unit 9 to which an interlock control signal is input from the outside in response to the occurrence of an event. The light emission control unit 7 that controls the lighting state of the light emission display unit 6 based on the interlocked control signal, and the light emission display unit 6 and the light emission control by converting the AC voltage of the commercial AC power source AC into a DC voltage of a desired voltage value. And a power supply unit 8 that generates an operating power supply for the unit 7. Here, circuit components constituting the circuit such as the signal input unit 9, the light emission control unit 7, and the power supply unit 8 are mounted on a printed wiring board (not shown) and housed in the switch body 1, for example. An output terminal of the light emission control unit 7 is electrically connected to the power supply electrode via a provided connection terminal (not shown).

  The decorative plate 5 is formed of a transparent, translucent, or milky white synthetic resin, and when the light emitting display 6 disposed on the back side of the upper, lower, left, and right frame pieces is turned on, the light emitting display 6 is transmitted through the frame piece of the decorative plate 5, so that the lighting state (lit or flashing) or the non-lighting state of the light emitting display unit 6 can be visually observed from the front side of the decorative plate 5. Note that, on the back surface of the decorative plate 5, a moisture absorbing sheet formed of a material having a moisture absorbing action such as silica so as to be in direct contact with the back surface of the light emitting display portion 6 only at a portion where the light emitting display portion 6 is formed. (Not shown) is provided integrally with the decorative plate 5, and the moisture absorption sheet in contact with the back surface of the light emitting display unit 6 absorbs moisture, thereby suppressing deterioration of the organic EL elements constituting the light emitting display unit 6. can do.

  In addition, the signal input unit 9 detects a human body detection signal from the human body detection sensor 22 that detects the presence or absence of a person in a detection area provided in the vicinity of the installation location of the switch device A, for example, a fire as an interlock control signal. An abnormality detection signal from the abnormality detection sensor 23 and a notification signal from another electric device 26 installed in the dwelling unit are input. It should be noted that the abnormality detected by the abnormality detection sensor 23 is not limited to a fire, and a sensor that detects an abnormality such as intrusion into a warning area or gas leakage may be used as the abnormality detection sensor.

  In the switch device A, for example, an on / off detector 24 that detects on / off of the contact 13 of the switch body 1 by detecting a load current, and the contact 13 based on the detection result of the on / off detector 24. When a predetermined energization time is counted from the time when the time is switched from OFF to ON, a time-up signal is output when the time is up, and a time measuring timer 25 that ends the time measuring operation when the contact 13 is switched from ON to OFF during the time counting is provided. The time-up signal of the timer 25 is input to the signal input unit 9 as an interlock control signal.

  Here, the control operation of the light emission display unit 6 by the light emission control unit 7 will be described. The light emission control unit 7 always lights the light emission display unit 6 with a desired light emission color (for example, green), and displays the position of the switch device A at night or in a dark place. The light-emitting display unit 6 is disposed on the back surface of the upper, lower, left, and right frame pieces of the decorative plate 5, and the entire decorative plate 5 appears to emit light when the light-emitting display unit 6 is turned on. Can be improved.

  The light emission control unit 7 performs switching control for switching on / off the light emission display unit 6 based on the interlock control signal input via the signal input unit 9. For example, the human body detection sensor 22 detects the human body. When a signal is input or an abnormality detection signal is input from the abnormality detection sensor 23, the light emission control unit 7 switches the light emission display unit 6 from a lighting state to a blinking state, so that the user is within the detection area. It is possible to visually notify that the vehicle has entered or that an abnormality has occurred.

  In addition, when the notification signal transmitted from another electrical device 26 is input via the signal input unit 9, the light emission control unit 7 changes the lighting state of the light emission display unit 6 according to the input of the notification signal. The change in the state of the electric device 26 is notified by the change in the lighting state. The other electric device 26 includes, for example, an interphone master, a rice cooker, a water heater, and the like. When the interphone master outputs a notification signal in response to a call from the door phone slave, a light emission control unit is input in response to the notification signal input. 7 blinks the light-emitting display unit 6 so that a visitor can be notified by the lighting state of the light-emitting display unit 6. In addition, when an electrical device that performs a predetermined operation in response to a switch operation, such as a rice cooker or a water heater, completes a predetermined operation (such as rice cooking or boiling), it emits light in response to the input of the notification signal. The control unit 7 can change the emission color of the light-emitting display unit 6 to notify the user that a predetermined operation has been completed (for example, rice has been cooked or hot water has boiled).

  Furthermore, the light-up control unit 7 is input with a time-up signal of the clock timer 25 as an interlock control signal via the signal input unit 9. Here, the timing timer 25 measures a predetermined energization time from the time when the contact 13 is switched from OFF to ON, generates a time-up signal when the time is up, and when the contact 13 is switched from ON to OFF during timing. Timekeeping operation has ended. When the time-up signal is input via the signal input unit 9, the light emission control unit 7 blinks the light emission display unit 6 and informs the user that the load L has been energized for a predetermined energization time. It notifies and prevents forgetting to turn off the switch.

  Note that the light emission control unit 7 may perform color temperature control for changing the color temperature of the light emission color of the light emission display unit 6 based on the interlock control signal input via the signal input unit 9. Changes the emission color to red when the abnormality detection sensor 23 detects an abnormality, so that the user can easily be notified that an abnormality has occurred. The light emission control unit 7 may control the lighting states of the plurality of light emitting display units 6 at once, or may control the lighting states of the light emitting display units 6 individually. When the load L corresponding to 1 is energized over a predetermined energization time, only the light emission control unit 6 around the piano handle 12 corresponding to this load (for example, the upper or lower side in FIG. 2) Only the three light emitting display portions 6) may be blinked.

  When there are a plurality of events to be notified depending on the lighting state of the light emission display unit 6, the light emission control unit 7 varies the cycle in which the light emission display unit 6 blinks or the light emission color of the light emission display unit 6 according to each event. It is preferable that the user can determine which event is being notified from the difference in blinking cycle or emission color.

  In the present embodiment, the light emitting display unit 6 made of organic EL elements is integrally provided on the back surface of the decorative plate 5, but the light emitting display unit made of organic EL elements is integrally provided on the front surface of the plate frame 4, The light emitted from the light emitting display part may be made visible through the decorative plate 5 by allowing the light emitted from the light emitting display part to pass through.
