So far, the operation of the wall switch 1 has been described. The signal processing unit 11 performs load control in accordance with the detection result of the operation detecting unit 11a. FIG. 3 shows a state transition diagram showing the operation of the signal processing unit 11.

In a state where the illumination load 100 is off (state ST1), the signal processing unit 11 controls the first drive circuit 16 to turn on the light-emitting diode 14 in green to indicate the position of the wall switch 1 and the position of the operation portion 20a.

When the illumination load 100 is off, when the operator performs a touch operation (short press operation) on the operation portion 20a during a period shorter than the predetermined time (event t1), the touch sensor 12 detects the touch. operating. When the touch sensor 12 detects the touch operation, the signal processing unit 11 causes the timer 11b to operate. The time measured by the timer 11b is shorter than the predetermined time, so the operation detecting unit 11a determines that the touch operation is a short press operation. When a short press operation is detected, the signal processing unit 11 reads the set value of the first dimming level from the memory 19. The signal processing unit 11 outputs the dimming signal S1 (from the output circuit 13 to the illumination load 100) in accordance with the read dimming level, and then turns on the illumination load 100 at the first dimming level (state ST2). In this embodiment, the first dimming level is set to 70%, so the lighting load 100 in state ST2 is turned on at the 70% dimming level. Further, the signal processing unit 11 controls the second drive circuit 17 to cause the buzzer 15 to emit a notification sound (for example, a sound like "哔"), thereby notifying the operator that the short press operation has been accepted. Further, the signal processing unit 11 controls the first driving circuit 16 to turn the light-emitting diode 14 into red, thereby visually indicating that the lighting load 100 has been turned on.

In the case where the lighting load 100 is off, when the operator performs a touch operation (long press operation) on the operation portion 20a during a period equal to or longer than the predetermined time (event t2), the touch sensor 12 detects the touch. Control operation. When the touch sensor 12 starts detecting, the signal processing unit 11 causes the timer 11b to operate. The time measured by the timer 11b is equal to or longer than the predetermined time, so the operation detecting unit 11a determines that the touch operation is a long press operation. When a long press operation is detected, the signal processing unit 11 reads the set value of the second dimming level from the memory 19. The signal processing unit 11 outputs the dimming signal S1 (from the output circuit 13 to the illumination load 100) in accordance with the read dimming level, thereby turning on the illumination load 100 at the second dimming level (state ST3). In this embodiment, the second dimming level is set to 100%, so the lighting load 100 in state ST3 is turned on in the full illumination state. Further, the signal processing unit 11 controls the second drive circuit 17 to cause the buzzer 15 to emit a notification sound (for example, a sound like "哔, 哔"), thereby notifying the operator that the long press operation has been accepted. Further, the signal processing unit 11 controls the first driving circuit 16 to turn the light-emitting diode 14 into red, thereby visually indicating that the lighting load 100 has been turned on.

When the illumination load 100 is turned on in the state of the first dimming level (state ST2), when the operator performs a touch operation (short press operation) on the operation portion 20a during a period shorter than the predetermined time (event t3), The touch sensor 12 detects a touch operation. When the illumination load 100 is turned on in the state of the second dimming level (state ST3), when the operator performs a touch operation (short press operation) on the operation portion 20a during a period shorter than the predetermined time (event t4), The touch sensor 12 detects a touch operation. When the touch sensor 12 detects the touch operation, the signal processing unit 11 causes the timer 11b to operate. The time measured by the timer 11b is shorter than the predetermined time, so the operation detecting unit 11a determines that the touch operation is a short press operation. When a short press operation is detected in the illumination state, the signal processing unit 11 causes the output circuit 13 to stop outputting the dimming signal S1, thereby turning off the illumination load 100 (state ST1). Further, the signal processing unit 11 controls the second drive circuit 17 to cause the buzzer 15 to emit a notification sound (for example, a sound like "哔"), thereby notifying the operator that the short press operation has been acquired. Further, the signal processing unit 11 controls the first driving circuit 16 to turn on the light-emitting diode 14 to be green, thereby indicating the position.

When the lighting load 100 is turned on in the state of the first dimming level (state ST2), when the operator performs a touch operation (long press operation) on the operation portion 20a for a period equal to or longer than the predetermined time (event t5), The touch sensor 12 detects a touch operation. When the touch sensor 12 detects the touch operation, the signal processing unit 11 causes the timer 11b to operate. The time measured by the timer 11b is equal to or longer than the predetermined time, so the operation detecting unit 11a determines that the touch operation is a long press operation. When a long press operation is detected, the signal processing unit 11 reads the set value of the second dimming level from the memory 19 to switch the dimming level. The signal processing unit 11 outputs the dimming signal S1 (from the output circuit 13 to the illumination load 100) in accordance with the read dimming level, thereby turning on the illumination load 100 at the second dimming level (state ST3). In this embodiment, the second dimming level is set to 100%, so the lighting load 100 in state ST3 is turned on in the full illumination state. Further, the signal processing unit 11 controls the second drive circuit 17 to cause the buzzer 15 to emit a notification sound (for example, a sound like "哔, 哔"), thereby notifying the operator that the long press operation has been accepted.

When the lighting load 100 is turned on in the second dimming level state (state ST3), when the operator performs a touch operation (long press operation) on the operation portion 20a for a period equal to or longer than the predetermined time (event t6), The touch sensor 12 detects a touch operation. When the touch sensor 12 detects the touch operation, the signal processing unit 11 causes the timer 11b to operate. The operation detecting unit 11a determines that the time measured by the timer 11b is equal to or longer than the predetermined time, and therefore determines that the touch operation is a long press operation. When a long press operation is detected, the signal processing unit 11 reads the set value of the first dimming level from the memory 19 to switch the dimming level. The signal processing unit 11 outputs the dimming signal S1 (from the output circuit 13 to the illumination load 100) in accordance with the read dimming level, thereby turning on the illumination load 100 at the first dimming level (state ST2). In this embodiment, the first dimming level is set to 70%, so the lighting load 100 in state ST3 is turned on at the 70% dimming level. Further, the signal processing unit 11 controls the second drive circuit 17 to cause the buzzer 15 to emit a notification sound (for example, a sound like "哔, 哔"), thereby notifying the operator that the long press operation has been accepted.

Summarizing the above operation, in the non-illuminated state, when the operator performs a short press operation on the operation portion 20a, the wall switch 1 turns on the illumination load 100 at the first dimming level, and when the operator performs a long press on the operation portion 20a In operation, the wall switch 1 turns the lighting load 100 on at the second dimming level. Further, in a state where the lighting load 100 is turned on at the first dimming level or the second dimming level, when the operator performs a short pressing operation on the operation portion 20a, the wall switch 1 turns off the lighting load 100. Further, in a state in which the lighting load 100 is turned on, when the operator performs a long press operation on the operation portion 20a, the wall switch 1 switches the dimming level of the illumination load 100 from the first dimming level to the second dimming level.

The dimming control unit is configured to control the lighting load 100 based on the detection result of the operation detecting unit 11a. When the operation detecting unit 11a detects the short pressing operation in the non-illuminated state (the lighting load 100 is off), the dimming control unit is configured to turn the lighting load 100 on at the predetermined first dimming level. When the operation detecting unit 11a detects the long pressing operation in the first state (the lighting load 100 is turned on at the first dimming level) or in the non-illuminating state, the dimming control unit is configured to set the lighting load 100 Turning on at a predetermined second dimming level (which is higher (lighter than) the first dimming level). When the operation detecting unit 11a detects the short pressing operation in the second dimming level (the lighting load 100 is turned on in the second dimming level) or in the first dimming level, the dimming control unit is Configured to turn off the lighting load 100.
