In the state in which the manual operation unit 2a1 is supported by the body 11, the back side of the manual operation unit 2a1 can be brought into contact with the deflection portion 11br of the cover 11b. When the user presses the manual operation unit 2a1, the manual operation unit 2a1 is pressed toward the cover 11b side. The switch master 10 presses the manual operation unit 2a1 to press the manual operation unit 2a1 to press the operator 2ac inside the body 11 with the flexure 11b. When the switch master 10 is pressed, the first operation switch 2a is turned ON. When the force pushed from the manual operation unit 2a1 disappears, the manual operation unit 2a1 can return to the original position by the reaction force of the operator 2ac or the like. When the manual operation unit 2a1 returns to the original position, the switch main unit 10 turns off the first operation switch 2a. For the first operation switch 2a, for example, a tactile switch can be used.

As shown in FIG. 2, the switch master 10 is provided with a ridge portion 2g4 on the surface of the cosmetic cover portion 2g. In the switch master 10, the ridge portion 2g4 of the cosmetic cover portion 2g can be used as a mark when the user operates the manual operation portion 2a1.

In the case of the present invention, the automatic switch to which the sensor for detecting a human body is attached is considered to have a configuration similar to that of the cosmetic cover 92g shown in FIG. The cosmetic cover 92g protrudes the light guiding member 96aa toward the back side. The cosmetic cover 92g allows the light from the light-emitting diodes housed in the body to be efficiently taken out to the outside of the automatic switch to which the human body detecting sensor is attached, by the light guiding member 96aa. However, the cosmetic cover 92g also efficiently introduces light from the outside of the automatic switch to which the human body detecting sensor is attached to the inner side of the body. Therefore, the automatic switch with the human body detecting sensor provided with the cosmetic cover 92g shown in FIG. 13 has a fear that the periphery of the light guiding member 96aa of the cosmetic cover 92g becomes dark when external light is irradiated. Further, the cosmetic cover 92g includes a light transmitting portion 92g1, a base portion 92g2, and a claw 92g3.

On the other hand, the switch base unit 10 can efficiently illuminate the light from the light-emitting diode 6a to the outside by inserting at least a part of the first cylindrical protrusion 11bs into the through hole 2f3 of the handle portion 2f. Further, the switch mother machine 10 can suppress the light from the outside from being absorbed by the inside of the introducer body 11. Therefore, the switch master 10 can suppress the degree of freedom in design by further reducing the mode display portion 6 that emits light from the light-emitting diode 6a due to external light when the light-emitting diode 6a is turned off.

Further, in the switch master 10, the handle portion 2f includes the second cylindrical projection 2fs, and protrudes toward the body 11 to surround the first cylindrical projection 11bs. The switch master 10 can prevent the light from the first cylindrical projection 11bs from leaking between the manual operation portion 2a1 and the cover 11b by the second cylindrical projection 2fs without the operation of the manual operation portion 2a1. Thereby, the switch mother machine 10 can illuminate the light from the light-emitting diode 6a more efficiently toward the side of the cosmetic cover portion 2g. Further, in the switch master 10, the body 11 is provided with the third cylindrical protrusion 11bt, and protrudes inside so as to surround the light-emitting diode 6a. As a result, the switch master 10 can suppress the light from the light-emitting diode 6a from diffusing inside the body 11, and the light of the light-emitting diode 6a can be efficiently emitted to the outside of the body 11.

In the switch master 10, a timer unit (not shown) is built in the control unit 4 for timing the lighting holding time for lighting the lighting load 42. The control unit 4 is configured to re-enter the sensor signal from the thermal sensor unit 1 during the timing of the lighting retention time, after the time from the re-input of the sensor signal to the predetermined lighting holding time The lighting load 42 is in a light-off state. Therefore, the timer portion is constituted by a triggerable timer, and the time from the re-input of the sensor signal to the predetermined lighting holding time can be counted.

In the state where the brightness detected by the brightness sensor 1s is darker than the threshold value of the preset brightness, the control unit 4 inputs the expression Detect according to the change in the heat incident on the thermal sensor unit 1 as a basic operation. The sensor signal of the human body is detected, and the lighting load 42 is illuminated. Further, the threshold value of the luminance may be, for example, first stored in the memory (not shown) of the control unit 4. The control unit 4 controls the shutter 5 to maintain the lighting state of the lighting load 42 between the predetermined lighting holding times counted by the timer unit.

The control unit 4 inputs the output of the thermal sensor unit 1 that is a sensor signal. The control unit 4 inputs the output of the first input determination unit 2. The control unit 4 inputs the output of the signal receiving unit 3. The control unit 4 detects whether there is a human body within a preset detection range according to the sensor signal from the thermal sensor unit 1, and outputs a control signal for controlling the shutter 5. The control unit 4 can be configured by, for example, a microcomputer including a CPU (Central Processing Unit).

The control unit 4 switches between the continuous lighting mode, the automatic lighting-off mode, and the forced-lighting mode by the pressing operation of the manual operation unit 2a1. The control unit 4 is electrically connected to each of the light-emitting diodes 6a. The control unit 4 controls the lighting of the plurality of light-emitting diodes 6a in accordance with the respective modes. The light-emitting diode 6a constitutes, for example, a mode display portion 6 that can display each mode of the switch master 10 by the light-emitting color and the lighting state. In other words, the control unit 4 can display each of the switched modes on the mode display unit 6 provided in the manual operation unit 2a1. In addition, the switch master 10 shown in FIG. 3 displays the continuous lighting mode as "continuous start". Further, the switch master 10 shown in FIG. 3 displays the automatic light-off mode as "automatic". Further, the switch master 10 shown in FIG. 3 displays the forced light-off mode as "OFF".

More specifically, in the case where the switch master 10 is in the forced light-off mode, for example, in the three light-emitting diodes 6a, the light-emitting diodes 6a provided on one side in the short-side direction (the left side of the paper surface of FIG. 3) are provided. Light up. In the switch mother machine 10, for example, in the three light-emitting diodes 6a, the light-emitting diodes 6a provided on one side in the short-side direction may be turned red. In the case where the switch master 10 is in the automatic light-off mode, for example, the light-emitting diode 6a provided at the center portion in the short-side direction is turned on. In the switch mother machine 10, for example, in the three light-emitting diodes 6a, the light-emitting diodes 6a provided at the central portion in the short-side direction may be lit green. The switch master 10 can also flash the green LED 6a provided at the center portion between the predetermined lighting holding times. The switch master 10 can also reduce the interval of the flash of the light-emitting diodes 6a provided at the center portion as the remaining time of the predetermined lighting stay time decreases. In the case where the switch master 10 is in the continuous lighting mode, for example, in the three light-emitting diodes 6a, the light-emitting diode 6a provided on the other side (the right side of the paper surface of FIG. 3) provided in the short-side direction is turned on. In the switch mother machine 10, for example, in the three light-emitting diodes 6a, the light-emitting diode 6a on the other side in the short-side direction may be illuminated in blue. That is, the light-emitting diode 6a displays the continuous lighting mode, the automatic lighting-off mode, and the mode display portion 6 by, for example, the difference of the red light, the green light, the blue light, or the flash. Forced off mode.

The switch base unit 10 is provided with a cosmetic cover 1d on the lower side of the manual operation unit 2a1. The cosmetic cover 1d is provided with an opening window portion 1db at a position facing the opening 11bm of the covering body 11b. The cosmetic cover 1d penetrates the boss portion 11bk so that the opening window portion 1db corresponds to the opening 11bm. The cosmetic cover 1d has a projection 1dk that protrudes more than the surface 2ab of one of the manual operation portions 2a1. The projection 1dk has an arc shape and is configured to protect the boss portion 11bk.

The switch master 10 includes a setting operation unit 7 that can set the detection sensitivity of the thermal sensor unit 1. The setting operation unit 7 can also have a function other than the detection sensitivity of the thermal sensor unit 1. The setting operation unit 7 may be provided with an operation unit capable of setting the lighting holding time in the automatic lighting-off mode. The operation unit 7 is set such that a part of the setting operation unit 7 is exposed on the first surface 11bp of the body 11. The manual operation unit 2a1 covers the setting operation unit 7 exposed on the first surface 11bp of the body 11. The setting operation unit 7 includes a first setting unit 7a and a second setting unit 7b.

The first setting unit 7a is attached to the first circuit board 16a by a knob or the like constituting the first setting unit 7a. The first setting unit 7a includes, for example, a first grip 7a1, and can rotate the operation shaft of the knob. The first setting unit 7a causes the first grip 7a1 of the first setting unit 7a to protrude from the first surface 11bp side of the body 11 through the third opening 11bh of the body 11. The first setting unit 7a is configured to set a lighting holding time for turning on the lighting load 42 in the automatic lighting-off mode. The switch mother machine 10 can appropriately set the lighting holding time in a range of, for example, 30 seconds to 30 minutes.

The second setting unit 7b mounts the rotation knob or the like constituting the second setting unit 7b on the first circuit board 16a. The second setting unit 7b includes, for example, a second grip 7b1, and can rotate the operation shaft of the rotary knob. The second setting unit 7b causes the second grip 7b1 of the second setting unit 7b to protrude from the first surface 11bp side of the body 11 through the fourth opening 11bi of the body 11. For example, the second setting unit 7b can set the brightness sensitivity level of the brightness sensor 1s in the range of "dark" to "bright". As the "darkness" of the brightness sensitivity level, for example, it may be 5 lux or less. As the "brightness" of the brightness sensitivity level, for example, it may be 100 lux or more.

In the switch master 10, for example, when the second setting unit 7b is set to "OFF", the function of the brightness sensor 1s can be stopped. When the second setting unit 7b is set to "closed", the switch master 10 can prevent the lighting load 42 in the room from being turned on when the switch main unit 10 is bright. The switch main unit 10 prevents the lighting load 42 in the room from being lit when the surroundings are bright, and energy saving can be sought. In the switch master 10, for example, by adjusting the threshold value of the brightness by the second setting unit 7b, it is possible to obtain the same effect as the detection sensitivity of the set thermal sensor unit 1 for detecting the presence or absence of the human body. In other words, in the switch master 10, the second setting unit 7b constitutes the setting operation unit 7 that sets the detection sensitivity of the thermal sensor unit 1. Further, the switch master 10 may include a setting operation unit 7 that directly adjusts and sets the detection sensitivity of the thermal sensor unit 1. The switch master 10 can directly adjust the detection sensitivity of the thermal sensor unit 1 by, for example, adjusting the degree of amplification when the amount of change in heat detected by the thermal sensor unit 1 is increased in accordance with the setting operation unit 7.

Next, the operation of the switch master 10 will be described in detail using FIG.

In the case where the switch master 10 is in the automatic light-off mode, if the thermal sensor unit 1 detects a change in heat at time t1, the thermal sensor unit 1 outputs a sensor signal. 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, the control unit 4 controls the shutter 5 in accordance with the sensor signal from the thermal sensor unit 1, and the illumination load 42 is turned on. The switch master 10 causes the timer unit of the control unit 4 to gradually decrease the value of the counter of the timer unit until the predetermined time elapses after receiving the sensor signal from the thermal sensor unit 1. At a predetermined time, reference is made to time t1 from time t2 of FIG. In the switch master 10, after the time t2 when the value of the counter of the timer section is "0", the control unit 4 controls the shutter 5 to turn off the illumination load 42. In other words, the switch master 10 turns the lighting load 42 on until a predetermined lighting hold time has elapsed.

Next, when the switch master 10 is in the automatic light-off mode, the thermal sensor unit 1 outputs the sensor signal when the thermal sensor unit 1 detects a change in heat at time t3, similarly to time t1. The switch base unit 10 causes the control unit 4 to control the shutter 5 in accordance with the sensor signal from the thermal sensor unit 1 to cause the illumination load 42 to be illuminated. In the case where the switch master 10 is in the automatic light-off mode, the lighting load 42 is in the lighting state, and if the signal receiving unit 3 receives the transmission signal from the operating slave 20 at time t4, the lighting holding time is shortened. The switch master 10 receives the sensor signal from the thermal sensor unit 1 at the time t3 when the control unit 4 lights the illumination load 42 to the time when the value of the counter of the timer unit becomes "0". At time t4 earlier than t5, the control unit 4 controls the shutter 5 to turn off the lighting load 42. In other words, the switch master 10 shortens the lighting holding time from the time t3 to the time t5 from the time t3 to the time t4.

In addition, the switch master 10 is provided with a mask period 1M. If the signal receiving unit 3 receives the transfer signal from the operation slave unit 20, the sensor signal from the thermal sensor unit 1 is prohibited between the predetermined periods. Control of the shutter 5 . The switch master 10 can set a mask period of 1 M for 5 seconds as a predetermined period of time, for example, in the control unit 4. The switch master 10 maintains the light-off state of the lighting load 42 between 1 M during the mask period. In the control unit 4 of the switch master 10, for example, in the mask period 1M, even if the sensor signal is received from the thermal sensor unit 1 at time t6, the light-off state of the illumination load 42 continues. The switch master 10 can display "OFF" in the mode display unit 6, for example, when the light-off state is continued. The switch master 10 returns to the automatic light-off mode in a manner that the illumination load 42 can be illuminated in response to the sensor signal from the thermal sensor unit 1 after the mask period 1M has elapsed at time t7. The switch master 10 can display "automatic" again in the mode display unit 6 as it returns to the automatic light-off mode.

Further, the switch master 10 switches the continuous lighting mode, the automatic lighting-off mode, and the forced-lighting mode each time the first operation switch 2a is operated. The mode display unit 6 displays "continuous start" in the continuous lighting mode. The mode display unit 6 displays "automatic" in the automatic light-off mode. The mode display unit 6 displays "OFF" in the forced light-off mode. The switch master 10 repeats the transition of each mode in the order of "off", "automatic", and "continuous start" in response to the operation of the first operation switch 2a.

In the system 30, for example, even if the operating sub-machine 20 is provided within the detection range of the thermal sensor unit 1, the user can operate the operating sub-machine 20 to turn off the lighting load 42. The system 30, in the automatic light-off mode, shortens the lighting holding time for lighting the lighting load 42 by transmitting a signal. Further, the system 30 may be configured to control the shutter 5, and in the automatic light-off mode, receive the transmission signal from the operation unit 20 and immediately turn off the illumination load 42. The system 30 allows the thermal sensor unit 1 to detect the human body operating the operating sub-machine 20 but does not illuminate the lighting load 42 to seek energy saving.

The system 30 can be turned on and off of the supply of power to the lighting load 42 by, for example, operating the slave unit 20 by a user remote from the switch master 10. The switch master 10 receives the transmission signal from the operation unit 20 in its internal signal receiving unit 3, and the control unit 4 switches the supply and stop of the power to the illumination load 42 in accordance with the transmission signal from the operation unit 20. The switch master 10, for example, stops the supply of power to the lighting load 42 in the automatic light-off mode, and the supply of power to the lighting load 42 can be performed by the transmission signal from the operating slave 20. That is, the control unit 4 of the switch master 10 lights the illumination load 42 by the transmission signal from the operation unit 20 in the automatic light-off mode. The control unit 4 turns off the illumination load 42 after the predetermined lighting stay time elapses from the lighting by the signal transmitted from the operation unit 20. In addition, the control unit 4 may be configured to be in a state in which the illumination load 42 is turned on between the predetermined lighting holding times by the transmission signal from the operating sub-machine 20, by the thermal sensor unit 1 The input of the sensor signal, and the scheduled lighting time is re-timed again. The control unit 4 can turn off the illumination load 42 after a predetermined lighting time has elapsed since the sensor signal from the thermal sensor unit 1 was input.

As shown in FIG. 16, for example, the operation unit 20 can be configured to include a case 21 in which the second input determination unit 22, the signal transmission unit 23, and the child control unit 24 can be housed. The casing 21 can be configured to have the same structure as the attachment claws 11bd of the body 11 of the switch mother machine 10, and is attached to the mounting frame 17. The operation unit 20 includes a surface portion 22g that covers the front surface of the casing 21. The cover portion 22g can be used as a piano key lever that constitutes the second operation switch 22a of the piano key switch.

In addition to the shutter 5 that opens and closes the supply of electric power to the lighting load 42, the switch main unit 10 may further include a second switch that opens and closes the supply of electric power to a load device such as a ventilating fan. Thereby, the switch master 10 can also control a load machine independent of the lighting load 42.
