The control unit 4 switches between the respective modes of the continuous lighting mode, the automatic lighting-off mode, and the forced-off mode each time the first operation switch 2a is operated. The control unit 4 displays the switched mode on the mode display unit 6 every time the first operation switch 2a is operated.

In the automatic light-off mode, when the control unit 4 determines that there is a human body in the detection area of the hot line sensing unit 1, the control unit 4 causes the illumination load 42 to be turned on in response to the sensing signal from the hot line sensing unit 1. In the automatic lighting-off mode, the control unit 4 sets the illumination load 42 to the lighting state after the illumination signal 42 is turned on in response to the sensing signal from the hot line sensing unit 1, and then sets it to the extinguished state. The control unit 4 built therein a time measuring unit (not shown) in order to calculate the lighting holding time at which the lighting load 42 is turned on.

On the first circuit board 16a, a wiring having a predetermined shape (not shown) is formed, and is electrically connected to various electronic components. The light-emitting diode 6a can display a continuous lighting mode, an automatic lighting-off mode, and a forced-out mode on the mode display unit 6 by, for example, red light emission, green light emission, or blue light emission or flicker. Further, the light-emitting diode 6a can also display the reception state of the signal receiving unit 3 in the system 30 and the like.

The circuit unit 16 is attached to the first circuit board 16a by the switch main body 2aa having the first operation switch 2a of the operator 2ac that is driven by the manual operation unit 2a1. The circuit unit 16 is attached to the first circuit board 16a by a member such as a regulator that constitutes the lighting holding time setting unit 7a. The circuit unit 16 sets the lighting holding time of the lighting load 42 through the lighting retention time setting unit 7a. The circuit unit 16 is attached to the first circuit board 16a such as a rotating adjuster that constitutes the brightness sensor adjusting unit 7b. The circuit unit 16 transmits the sensitivity of the brightness detected by the brightness sensor 1s through the brightness sensor adjustment unit 7b.

In the switch master 10, the operation portion 2ac that drives the switch body 2aa is pressed by the flexure portion 11br that is bent toward the inner side of the body 11 by the pressing of the manual operation portion 2a1.

The lighting retention time setting unit 7a includes, for example, a first knob 7a1 for rotating the operation shaft of the adjuster. The lighting retention time setting unit 7a and the third window hole 11bh of the transmission body 11 project the first knob 7a1 of the lighting retention time setting unit 7a toward the first surface 11bp side of the body 11. The lighting retention time setting unit 7a is configured to be able to set the lighting holding time for lighting the lighting load 42 in the automatic lighting-off mode. In the switch master 10, when the manual operation portion 2a1 provided to be substantially flush with the second surface 9ab of the flat plate 9 is removed, the setting operation portion 7 is exposed.

The switch master 10 can appropriately adjust the lighting holding time of the lighting load 42 by the lighting holding time setting unit 7a. The brightness sensor adjustment unit 7b includes, for example, a second knob 7b1 for rotating an operation shaft of the rotation adjuster. The brightness sensor adjustment unit 7b causes the second knob 7b1 of the brightness sensor adjustment unit 7b to protrude toward the first surface 11bp side of the body 11 of the fourth window hole 11bi of the actuator body 11. The brightness sensor adjustment unit 7b can set the brightness sensitivity level of the brightness sensor 1s to a range of "dark" to "bright", for example. The "darkness" of the brightness sensitivity level can be set, for example, below 5 lux. The "brightness" of the brightness sensitivity level, for example, can be set at 100 lux or more. The control unit 4 of the switch master 10 can stop the function of the brightness sensor 1s by setting the brightness sensor adjustment unit 7b to "cut", for example. When the brightness sensor adjusting unit 7b is appropriately set, the switch mother machine 10 can prevent the lighting load 42 in the house from being turned on when the periphery of the switch main unit 10 is bright. The switch master 10 can save energy by preventing the lighting load 42 in the house from being lit when the surroundings are bright.

In the switch master 10, for example, the brightness sensor adjustment unit 7b adjusts the threshold value of the brightness, and as a result, the same effect as the detection sensitivity of the set hot line sensing unit 1 for detecting the presence or absence of the human body can be obtained. In other words, in the switch master 10, the brightness sensor adjustment unit 7b constitutes the setting operation unit 7 that sets the detection sensitivity of the heat line sensing unit 1. The switch master 10 may further include a setting operation unit 7 that directly adjusts the detection sensitivity of the set hot line sensing unit 1. For example, the switch master 10 can adjust the detection sensitivity of the hot line sensing unit 1 by adjusting the increase amount when the amount of change in the hot line detected by the hot line sensing unit 1 is increased by the setting operation unit 7.

Next, the operation of the switch master 10 will be described in detail with reference to FIG.

When the hot line sensing unit ₁ detects a change in the hot line at time t1, the hot line sensing unit 1 outputs a sensing signal when the automatic switching unit 10 detects the automatic light-off mode. When the switch master 10 is in the automatic light-off mode, "automatic" is displayed on the mode display unit 6. In the switch master 10, based on the sensing signal from the hot line sensing unit 1, the control unit 4 controls the shutter 5 to bring the illumination load 42 to the lighting state. In the switch master 10, the count 値 of the timer unit is gradually decreased until the timer unit of the control unit 4 receives the sensing signal from the hot line sensing unit 1 and then elapses for a predetermined period of time. For a predetermined time, reference is made to time t ₁ to time t _{2 of} Fig. 15 . Switch point 10, the timer count portion Zhi "0" after the time t _2, the control unit 4 controls the shutter 5, 42 lighting load is off. In other words, the switch master 10 lights the illumination load 42 until the preset lighting hold time elapses.

Next, the switch point 10, the lighting in the automatic off mode, the same time t _1, when the sensing wire portion 1 at a time t ₃ a change is detected wire, wire sensing unit will output a sensing signal. In the switch master 10, based on the sensing signal from the hot line sensing unit 1, the control unit 4 controls the shutter 5 to bring the illumination load 42 to the lighting state. Switch point 10, flickering in the automatic mode, when the operation of the slave 20 receives a signal 42 conveys lighting load off the lighting load 42 from the lighting state, and the signal receiving section 3 at time t _4, The lighting holding time of the lighting load 42 is shortened. In the switch point 10, in front of more than 4 t ₅ according to the sensing signal from the sensing wire portion of the lighting load 1 is lighted in time 42 of the control unit counts the time t ₃ to time Zhi portion is "0" the time T _4, the control unit 4 controls the shutter 5, 42 lighting load is off. That is, the switch point 10, the time t ₃ to time t ₅ the lighting holding time is shortened to time t ₃ to time t _4.

Further, the switch master 10 is provided such that when the signal receiving unit 3 receives the communication signal from the operation unit 20, the illumination load 42 due to the sensing signal from the hot line sensing unit 1 is illuminated for a predetermined period of time. 1M is prohibited during the obscuration period. In the switch master 10, for example, the masking period 1M of 5 seconds can be set in the control unit 4 as a predetermined period. The switch master 10 maintains the extinguished state of the illumination load 42 between the shielding periods 1M. In the occlusion period 1M from the time t ₄ to the time t ₇ at which the illumination load 42 is in the extinguished state, for example, even if the control unit 4 receives the sensing signal from the hot line sensing unit 1 at time t ₆ , the switch master 10 makes The extinguished state of the lighting load 42 continues. When the switch master 10 continues in the extinguished state, for example, "cut" can be displayed on the mode display unit 6. The switch master 10 returns to the automatic light-off mode in which the illumination load 42 can be turned on in response to the sensing signal from the hot line sensing unit 1 at time t ₇ after the mask period 1M has elapsed. The switch master 10 can display "automatic" again in the mode display unit 6 as it returns to the automatic light-off mode.

The switch master 10 switches between the continuous lighting mode, the automatic lighting extinguishing mode, and the forced extinguishing mode each time the first operation switch 2a is operated. The mode display unit 6 displays "continuous lighting" in the continuous lighting mode. The mode display unit 6 displays "automatic" in the automatic light-off mode. The mode display unit 6 displays "cut" in the forced extinguish mode. The switch master 10 shifts each mode in the order of "cut", "automatic", and "continuously lit" in response to the switching of the operation mode.

In the system 30, for example, even if the operation unit 20 is provided in the detection area of the hot line sensing unit 1, the operation load unit 20 can be operated by a person to turn off the illumination load 42. Further, in the automatic lighting off mode, the system 30 shortens the lighting holding time of the lighting load 42. The system 30 does not illuminate the lighting load 42 even after the hot line sensing unit 1 detects the person operating the operating unit 20, thereby achieving energy saving.

The operation slave unit 20 constitutes a configuration in which the switch master 10 is operable. The slave unit 20 is operated to transmit a signal for controlling the switch master 10 to operate the switch master 10. The operation unit 20 can transmit a communication signal for controlling the switch main unit 10. Therefore, the operation slave unit 20 can be configured to include the second input determination unit 22 that determines the on/off operation of the second operation switch 22a that is manually operated, and the control signal transmission unit 23 that is based on the operation signal from the second input determination unit 22.

The slave unit 20 may include a slave control unit 24 that controls the signal transmitting unit 23 that transmits a signal to the switch master 10 based on an operation signal from the second input determination unit 22. The operation unit 20 can transmit the communication signal to the switch base unit 10 in a wired manner, and can also transmit the communication signal to the switch base unit 10 in a wireless manner. The system 30 can perform power supply to the lighting load 42 side and stop of power supply by operating the slave unit 20, for example, by a person remote from the switch base unit 10. In the switch master 10, for example, the internal signal receiving unit 3 receives a communication signal from the operation unit 20, and the control unit 4 switches the supply of power to the illumination load 42 side and the stop of power supply in accordance with a transmission signal from the operation unit 20.
