However, when the switch box is not embedded, the mounting frame 9 is fixed to the wall plate using a conventionally known pinch fitting (not shown).

  Further, the front wall of the cover 12 is formed in a stepped shape on both left and right end portions. Furthermore, the recessed part 128 is formed in the up-down direction substantially center in the said edge part, respectively (refer FIG.1 and FIG.6). That is, the operation unit 2 is detachably attached to the switch body 1 by hooking the hooking claws 221 of the two mounting pieces 220 provided on the housing 22 to the front end edges of the two recesses 128, respectively. (See FIGS. 7 and 8).

  Here, when the operation unit 2 is attached to the switch body 1, the second connector 28 of the operation unit 2 and the first connector 56 of the switch body 1 are electrically and mechanically connected. That is, the eight contacts 280 of the second connector 28 are respectively inserted into the eight insertion openings 560 opened on the front surface of the first connector 56, and the eight contacts provided inside the first connector 56, respectively. Individually and electrically connected (see FIG. 5). A pair of protective walls 235 provided on the housing 22 (base 23) of the operation unit 2 are inserted into insertion holes 124 provided on the body 10 (cover 12) of the switch body 1 (see FIG. 4). ). Therefore, even if an external force such as an impact force is applied to the operation unit 2, the external force is hardly applied to the first connector 56 and the second connector 28 because they are protected by the pair of protective walls 235. 56 can be prevented.

  Next, the operation of the switch device of this embodiment will be described in detail with reference to the system configuration diagram of FIG. First, the system configuration of the system (illumination system) in FIG. 10 will be briefly described.

  This system is composed of, for example, two switch devices SA and SB, two illumination loads 4A and 4B, and two transmitters WA and WB. Note that the switch device of this embodiment is used for both of these two switch devices SA and SB. However, this system configuration is only an example of a system configuration for controlling the load using the switch devices SA and SB of the present embodiment.

  One switch device SA (hereinafter referred to as the first switch device) is electrically connected to the AC power supply 3 and the illumination load 4A (hereinafter referred to as the first illumination load) via the electric wire 100. The other switch device SB (hereinafter referred to as the second switch device) is electrically connected to the AC power supply 3 and the illumination load 4B (hereinafter referred to as the second illumination load) via the electric wire 100. . Further, the first switch device SA and the second switch device SB are electrically connected by the signal line 101.

  One transmitter WA (hereinafter referred to as a first transmitter) is registered in the first switch device SA, and is configured to transmit a radio signal using radio waves as a communication medium to the first switch device SA. The The other transmitter WB (hereinafter referred to as a second transmitter) is registered in the second switch device SB, and is configured to transmit a radio signal using radio waves as a communication medium to the second switch device SB. The The radio signals transmitted from the transmitters WA and WB include control data for controlling (lighting, extinguishing or dimming) the respective lighting loads 4A and 4B, and specific to each transmitter WA and WB. And identification information.

  Here, the operation unit 2 of the first switch device SA has two operation areas 201A and 202A arranged vertically. The operation unit 2 of the second switch device SB has two operation areas 201B and 202B arranged vertically. For example, in the first switch device SA, when the upper operation area (hereinafter referred to as the first operation area 201A) is touch-operated, the operation unit 2 indicates that the first operation area 201A is touch-operated. A first operation signal is output. In the switch body 1 of the first switch device SA, the control unit 5 that has received the first operation signal turns on or turns off the first lighting load 4A by turning on the switch element 50.

  Similarly, when the upper operation area (hereinafter referred to as the first operation area 201B) is touched in the second switch device SB, the operation unit 2 confirms that the first operation area 201B has been touched. The first operation signal shown is output. In the switch body 1 of the second switch device SB, the control unit 5 that has received the first operation signal turns on or turns off the second illumination load 4B by turning on the switch element 50.

  When the lower operation area (hereinafter referred to as the second operation area 202A) is touch-operated in the first switch device SA, the operation unit 2 indicates that the second operation area 202A has been touch-operated. The second operation signal shown is output. In the switch body 1 of the first switch device SA, the control unit 5 that has received the second operation signal transmits a control signal for the second lighting load 4B from the signal transmission unit 55 to the second switch device SB via the signal line 101. (Send).

  In the second switch device SB, the signal transmission unit 55 receives the control signal transmitted from the first switch device SA via the signal line 101 and outputs the control signal to the control unit 5. The control unit 5 of the second switch device SB turns on (or turns off) the second lighting load 4B by turning on (or turning off) the switch element 50 based on the control signal received from the signal transmission unit 55.

  Furthermore, in the second switch device SB, when a lower operation area (hereinafter referred to as a second operation area 202B) is touched, the operation unit 2 confirms that the second operation area 202B has been touched. The second operation signal shown is output. In the switch body 1 of the second switch device SB, the control unit 5 that has received the second operation signal transmits a control signal for the first lighting load 4A from the signal transmission unit 55 to the first switch device SA via the signal line 101. (Send).

  In the first switch device SA, the signal transmission unit 55 receives the control signal transmitted from the second switch device SB via the signal line 101 and outputs the control signal to the control unit 5. Based on the control signal received from the signal transmission unit 55, the control unit 5 of the first switch device SA turns on (or turns off) the switch element 50 to turn on (or turn off) the first lighting load 4A.

  In each of the switch devices SA and SB, the control unit 5 can cause the light emitting diode 200 of the touch sensor unit 20 to emit light when the switch element 50 is turned off, that is, when the illumination loads 4A and 4B are turned off. preferable. That is, in the situation where the lighting loads 4A and 4B are dark because they are turned off, the front surfaces of the switch devices SA and SB (the front surface of the operation unit 2) emit light to inform the positions of the switch devices SA and SB. be able to. Alternatively, the control unit 5 may notify the positions of the operation areas 201A (201B) and 202A (202B) by causing the light emitting diode 200 of the touch sensor unit 20 to emit light.

  By the way, in a general mechanical switch device, an operation feeling is changed or a sound (operation sound) is generated in accordance with switching of the contacts, so that the operator can be notified that the operation has been accepted. On the other hand, in the switch devices SA and SB, even if the operation unit 2 is touch-operated, the operation feeling does not change or the operation sound does not occur, so it may be difficult for the operator to know whether or not the operation has been accepted. . Therefore, when receiving an operation signal from the operation unit 2, the control unit 5 preferably outputs a control signal to the operation unit 2 and outputs an operation sound (for example, a “beep” sound) from the sound output unit 29. . However, it is preferable that whether or not the operation sound is output can be set by the dip switch 521 of the setting unit 52.

  When a radio signal is transmitted from the first transmitter WA, the radio communication unit 54 of the first switch device SA receives the radio signal, acquires control data included in the radio signal, and sends it to the control unit 5. Output. Based on the control data received from the wireless communication unit 54, the control unit 5 of the first switch device SA turns on (or turns off) the switch element 50 to turn on (or turn off) the first lighting load 4A.

  When a radio signal is transmitted from the second transmitter WB, the radio communication unit 54 of the second switch device SB receives the radio signal, acquires control data included in the radio signal, and outputs the control data to the control unit 5. . The control unit 5 of the second switch device SB turns on (or turns off) the second lighting load 4B by turning on (or turning off) the switch element 50 based on the control data received from the wireless communication unit 54.

  Here, in each of the switch devices SA and SB, the control unit 5 is preferably configured to operate by selectively selecting the first operation mode and the second operation mode. The selection (setting) of the first operation mode and the second operation mode is preferably performed by the dip switch 521. That is, the control unit 5 reads the state (ON or OFF) of the dip switch 521, for example, selects the first operation mode if the dip switch 521 is ON, and selects the second operation mode if the dip switch 521 is OFF. Select.

  The control unit 5 that has selected the first operation mode turns on / off the switch element 5 in response to the first operation signal, and transmits the control signal from the signal transmission unit 55 in response to the second operation signal. On the other hand, the control unit 5 that has selected the second operation mode turns on and off the switch element 5 in response to the second operation signal, and transmits the control signal from the signal transmission unit 55 in response to the first operation signal. .

  For example, in the system configuration shown in FIG. 10, it is preferable that the first operation mode is selected in the first switch device SA and the second operation mode is selected in the second switch device SB. In this case, when the first operation area 201A of the first switch device SA is touch-operated or the first operation area 201B of the second switch device SB is touch-operated, the first lighting load 4A is turned on or off. . On the other hand, when the second operation area 202A of the first switch device SA is touched or the second operation area 202B of the second switch device SB is touched, the second illumination load 4B is turned on or off.

  That is, when the user wants to turn on and off the first illumination load 4A, the user can touch either the first operation area 201A of the first switch device SA or the first operation area 201B of the second switch device SB. Good. In addition, when the user wants to turn on and off the second lighting load 4B, the user can touch either the second operation area 202A of the first switch device SA or the second operation area 202B of the second switch device SB. Good.

  Here, it is assumed that the first operation mode is selected for both of the two switch devices SA and SB. In this case, when the user wants to turn on and off the first lighting load 4A, the user performs a touch operation on the first operation area 201A in the first switch device SA and a touch operation on the second operation area 202B in the second switch device SB. There must be. Further, when the user wants to turn on and off the second lighting load 4B, the user must perform a touch operation on the second operation area 202A in the first switch device SA and a touch operation on the first operation area 201B in the second switch device SB. I must.

  That is, two operation areas (first operation areas 201A and 201B and second operation areas 202A and 202B) and two illumination loads (first illumination load 4A and second illumination load 4B) of the two switch devices SA and SB. The correspondence with is reversed. Therefore, it is not convenient for users.

  On the other hand, in the switch devices SA and SB of the present embodiment, the control unit 5 is configured to selectively select and execute the first operation mode and the second operation mode. As a result, two operation areas (first operation areas 201A and 201B and second operation areas 202A and 202B) of the two switch devices SA and SB and two illumination loads (first illumination load 4A and second illumination load 4B). ) Can be matched with each other. Therefore, the switch devices SA and SB of the present embodiment can improve the usability for the user.

  Next, a procedure for registering the identification information of the transmitters WA and WB in the switch devices SA and SB in the system configuration shown in FIG. 10 will be described.

  A person who performs registration work (hereinafter referred to as an operator) removes the operation unit 2 from the switch body 1 and presses one operation button 1210 out of the three operation buttons 1210 exposed on the front surface of the switch body 1. To do. When the push button 1210 is pressed, the push button switch 520 of the setting unit 52 is turned on, and a setting signal (registration mode setting signal) is output from the setting unit 52 to the control unit 5. When the control unit 5 receives the registration mode setting signal, the control unit 5 shifts to the registration mode and notifies the operator by blinking the light emitting element 522, for example.

  After confirming blinking (or lighting) of the light emitting element 522 through the window hole 123, the worker transmits a radio signal including identification information from a transmitter (for example, the first transmitter WA). The wireless communication unit 54 receives the wireless signal transmitted from the first transmitter WA, and the identification information included in the wireless signal is output to the control unit 5. After storing the identification information received from the wireless communication unit 54 in the memory unit 53, the control unit 5 notifies the operator that the identification information has been registered by, for example, lighting the light emitting element 522 for a certain period of time. Thereafter, when the operator presses the operation button 1210 for a predetermined time or when a predetermined time has elapsed since the shift to the registration mode, the control unit 5 ends the registration mode and shifts to the normal operation mode.

  In other words, the wireless signals transmitted from the transmitters WA and WB include identification information unique to the transmitters WA and WB. Then, the control unit 5 of each switch device SA, SB performs the wireless communication only when the identification information included in the wireless signal received by the wireless communication unit 54 matches the identification information stored in the memory unit 53. Based on the control data included in the signal, the switch element 50 is turned on and off. The identification information of one transmitter WA (or WB) may be registered in common with the two switch devices SA and SB. In this case, the lighting load 4A (or 4B) is simultaneously turned on and off by the two switch devices SA and SB by a radio signal transmitted from the transmitter WA (or WB) in which the identification information is registered in common. Can do.

  Here, the switches 520 and 521 of the setting unit 52 are operated only during setting, and are not operated during normal use. If the switches 520 and 521 of the setting unit 52 having a very low operation frequency are provided on the operation surface of the operation unit 2 (the front surface of the housing 22), the operation region 201A with a high operation frequency becomes small. End up.

  On the other hand, in the switch devices SA and SB of the present embodiment, the operation piece 121, the push button switch 520, the dip switch 521, and the like constituting the setting unit 52 are provided on the front side of the switch body 1, and normally It is hidden by the operation unit 2 mounted on the front side. Therefore, compared with the case where the setting unit 52 is provided in the operation unit 2, it is possible to ensure a sufficient size as the operation region of the touch sensor unit 20 without increasing the size of the housing 22.

  As described above, the switch device of the present embodiment includes the switch body 1 and the operation unit 2.

The operation unit 2 is configured so that the front surface of the housing 22 is the detection surface of the touch sensor unit 20. The switch body 1 turns on / off the switch element 50 corresponding to the detection result of the touch sensor unit 20 and the switch element 50 that turns on and off the power supply from the external power supply (AC power supply 3) to the load (lighting load 4). And a control unit 5. The switch body 1 includes a setting unit 52 having one or more switches 520 and 521, a switch element 50, the control unit 5, and a box-shaped container 10 that houses the setting unit 52. The control unit 5 is configured to perform various settings by operating the switches 520 and 521 of the setting unit 52. As for the container 10, the operation part (operation piece 121, window hole 122,123) for operating the some switches 520 and 521 which the setting part 52 has is provided in the front surface. The operation unit 2 is attached to the container body 10 so as to be displaceable (detachable) between a first position that covers the front surface of the container body 10 and a second position that exposes the front surface of the container body 10.

  The switch device of the present embodiment is configured as described above. Normally, the front surface of the body 10 is covered with the operation unit 2, so that it is possible to avoid erroneous operation of the switches 520 and 521 of the setting unit 52. Further, if the operation unit 2 is displaced to the second position and the front surface of the body 10 is exposed, the switches 520 and 521 of the setting unit 52 can be easily operated, so that a decrease in operability can be avoided. it can. As a result, the switch device of the present embodiment can suppress an increase in the size of the switch body 1 while avoiding an erroneous operation and a decrease in operability.

  Further, in the switch device of the present embodiment, the housing 22 is preferably provided with a hooking portion (hooking hook 221) that is detachably hooked on a part (the recess 128) of the container body 10. However, the operation unit 2 may be configured to be rotatable between the first position and the second position with respect to the body 10 of the switch body 1.

  Furthermore, in the switch device of the present embodiment, the switch body 1 is preferably provided with a receiving unit (wireless communication unit 54) that is housed in the body 10 and receives radio signals transmitted from the transmitters WA and WB. . The control unit 5 is preferably configured to turn on and off the switch element 50 in response to an instruction included in the wireless signal received by the receiving unit (wireless communication unit 54). Furthermore, it is preferable that the control unit 5 is configured to allow the instruction given from the transmitters WA and WB to be accepted when the switch 520 of the setting unit 52 is operated.

Preferably, the device 50 is configured to be prohibited from turning on and off.

  If the switch apparatus of this embodiment is comprised as mentioned above, generation | occurrence | production of the malfunction that a load (lighting load 4A, 4B) is controlled during a setting operation | work irrespective of an operator's intention can be prevented.

  By the way, when the operation unit 2 is removed from the switch body 1 for the setting operation and the registration operation as described above, the switch devices SA and SB are arranged along the removal direction (front-rear direction) and the first connector 56 and the second connector 56. Stress is generated in the connector 28. These stresses are forces in directions to separate the first connector 56 and the second connector 28 from the control board 13 and the sensor board 26 on which they are mounted, respectively. Therefore, there is a possibility that cracks may occur in the solder joining the respective substrates 13 and 26 and the connector terminal portions of the first connector 56 and the second connector 28.

  On the other hand, in the switch devices SA and SB of the present embodiment, the movement of the first connector 56 in the front-rear direction is restricted by the first restricting portion 127 provided in the container body 10 (cover 12). Therefore, cracks are hardly generated in the solder joining the control board 13 and the connector terminal portion of the first connector 56.
