Hereinafter, a switch device according to an embodiment of the present disclosure will be described in detail with reference to the drawings. However, each figure described in the following embodiments is a schematic diagram, and the respective ratios of the sizes and thicknesses of each component do not necessarily reflect the actual size ratios. Note that the configuration described in the embodiments below is only an example of the present disclosure. The present disclosure is not limited to the following embodiments, and various changes can be made depending on the design etc. as long as the effects of the present disclosure can be achieved.

First, a circuit configuration of a switch device 1 (hereinafter abbreviated as switch device 1) according to an embodiment will be described. The switch device 1 includes a first circuit block 4, a second circuit block 5, and a terminal block 6, as shown in FIG.

The terminal block 6 includes four terminals (a first terminal 61, a second terminal 62, a third terminal 63, and a fourth terminal 64). The first terminal 61 is electrically connected to the positive electrode (HOT side electrode) of the AC power supply X1 (for example, a single-phase two-wire AC power supply with an effective value of 100 V). The second terminal 62 is electrically connected to the negative electrode (COLD side electrode) of the AC power supply X1. The third terminal 63 is electrically connected to the first power terminal of the lighting load W1 (for example, an LED lighting fixture). The fourth terminal 64 is electrically connected to the second power supply terminal of the lighting load W1. Note that the second terminal 62 and the third terminal 63 are electrically connected via a conductor (for example, an electric wire).

The first circuit block 4 includes a switching element 41, a drive circuit 42, and a DC power supply circuit 43.

The DC power supply circuit 43 converts the AC voltage supplied from the AC power supply X1 via the first terminal 61 and the second terminal 62 into DC voltage. The DC power supply circuit 43 includes, for example, a power factor correction circuit (step-up chopper circuit) and a step-down chopper circuit, and preferably outputs a DC voltage of about 5 to 15V. The DC power supply circuit 43 supplies the converted DC voltage (hereinafter referred to as control voltage) to the drive circuit 42 and the second circuit block 5.

The switching element 41 is provided on the electrical line that electrically connects the first terminal 61 and the fourth terminal 64 of the terminal block 6 . The switching element 41 is composed of an electromagnetic relay, a semiconductor relay, or a semiconductor switching element. When the switching element 41 is on, the first terminal 61 and the fourth terminal 64 are electrically connected via the electric path. On the other hand, when the switching element 41 is off, the electric path is interrupted and the first terminal 61 and the fourth terminal 64 are not electrically connected. That is, when the switching element 41 is on, a closed circuit is formed by the AC power source X1, the lighting load W1, the terminal block 6, and the switching element 41, and AC power is supplied from the AC power source X1 to the lighting load W1. On the other hand, when the switching element 41 is off, a closed circuit is not formed by the AC power supply X1, the lighting load W1, the terminal block 6, and the switching element 41, and AC power is not supplied from the AC power supply X1 to the lighting load W1.

The drive circuit 42 turns on and off the switching element 41 under the control of a control circuit 53, which will be described later.

The second circuit block 5 includes a human body detection sensor 51, a push button switch 52, a control circuit 53, and a display lamp 54.

The human body detection sensor 51 is a so-called passive infrared motion sensor. The infrared motion sensor has a plurality of pyroelectric elements, and detects a human body that emits infrared rays according to the amount of change in infrared rays received by the plurality of pyroelectric elements. That is, the human body detection sensor 51 is configured to output a human body detection signal when a human body is present in the detection area.

The push button switch 52 has a mechanical normally open contact and a push button 520 (see FIG. 3) that closes (turns on) the normally open contact when external force is applied. A control voltage is applied to the normally open contact of pushbutton switch 52.

The display lamp 54 includes, for example, an LED (Light Emitting Diode) chip that emits red light and an LED chip that emits green light. The indicator lamp 54 selectively emits red light and green light under the control of the control circuit 53.

The control circuit 53 is composed of a microcontroller. Control circuit 53 has multiple input ports and output ports. A human body detection sensor 51 is electrically connected to the first input port, and a push button switch 52 is electrically connected to the second input port. That is, when the human body detection sensor 51 detects a human body, a high level signal (human body detection signal) is input to the first input port. Furthermore, when the pushbutton switch 52 is off, the input voltage at the second input port is maintained at a high level (control voltage), but when the pushbutton switch 52 is on, the input voltage at the second input port is maintained at a high level (control voltage). changes to low level. Therefore, the control circuit 53 determines that the operation signal has been input from the push button switch 52 when the input voltage of the second input port changes from high level to low level.

The drive circuit 42 is electrically connected to the first output port of the control circuit 53 . The control circuit 53 outputs a control signal from a first output port. The drive circuit 42 drives the switching element 41 upon receiving a control signal from the control circuit 53.

An indicator lamp 54 is electrically connected to the second output port of the control circuit 53. The control circuit 53 outputs a drive signal from the second output port to cause the indicator lamp 54 to emit light.

The control operation of the control circuit 53 will be explained in more detail. When an operation signal is input to the second input port in a situation where the switching element 41 is off (a situation where the lighting load W1 is off), the control circuit 53 outputs a control signal from the first output port. The output signal causes the drive circuit 42 to turn on the switching element 41. Furthermore, when the human body detection signal is input from the human body detection sensor 51 to the first input port in a situation where the lighting load W1 is off, the control circuit 53 outputs a control signal from the first output port. The drive circuit 42 turns on the switching element 41. When the switching element 41 is turned on, the lighting load W1 is turned on.

When the lighting load W1 is off, the control circuit 53 causes the indicator lamp 54 to emit green light, thereby making it easier to visually recognize the position of the switch device 1 even in a dark environment. Further, in a situation where the lighting load W1 is lit, the control circuit 53 causes the indicator lamp 54 to emit red light to indicate that the lighting load W1 is lit.

On the other hand, in a situation where the lighting load W1 is lit, when an operation signal is input to the second input port, the control circuit 53 outputs a control signal from the first output port to cause the drive circuit 42 to switch the switching element. 41 is turned off. Furthermore, when the human body detection signal is no longer input to the first input port from the human body detection sensor 51 in a situation where the lighting load W1 is lit, the control circuit 53 outputs a control signal from the first output port. The drive circuit 42 turns off the switching element 41. When the switching element 41 is turned off, the lighting load W1 is turned off.

Here, when the input of the human body detection signal stops while the lighting load W1 is turned on, the control circuit 53 starts a timer built in the microcontroller, and when the timer time reaches a predetermined delay time. A control signal may also be output. However, it is preferable that the control circuit 53 restarts the timer and resets the measured time if the human body detection signal is input again to the first input port before the time measured by the timer reaches the delay time. Further, if an operation signal is input to the second input port before the timer's time reaches the delay time, the control circuit 53 stops the timer and outputs a control signal to turn off the switching element 41. It is preferable to do so.

Note that the control circuit 53 may alternatively select and execute the first control operation and the second control operation. For example, the control circuit 53 may alternately select the first control operation and the second control operation when the operation signal is input multiple times (for example, twice) within a short period of time (for example, 500 milliseconds). is preferred.

When executing the first control operation, the control circuit 53 switches the lighting load W1 on and off according to the human body detection signal from the human body detection sensor 51. Furthermore, when executing the second control operation, the control circuit 53 turns on and off the lighting load W1 in response to the input of the operation signal from the push button switch 52, regardless of the human body detection signal of the human body detection sensor 51. Switch.

Next, the structure of the switching device 1 will be explained in detail with reference to FIGS. 2 to 8. However, in the following description, unless otherwise specified, the front-back, left-right, and up-down directions indicated by arrows in FIG. 3 are defined as the front-back, left-right, and up-down directions of the switch device 1.

The switch device 1 includes a container body 2 that accommodates a first circuit block 4, a second circuit block 5, and a terminal block 6 therein, and an operation handle rotatably supported on the front surface of the container body 2. 3 (see FIG. 3).

The container body 2 has a box-shaped body 20 with an open front and a cover 21 attached to the front end of the body 20.

The body 20 is made of a synthetic resin material and is formed into a rectangular tube shape with an open front and a bottom. Four electric wire insertion holes 200 are provided on the bottom surface (rear surface) of the body 20 (see FIG. 2B). These four wire insertion holes 200 are arranged in a line in the vertical direction on the bottom surface of the body 20. Further, these four wire insertion holes 200 face the four terminal holes 66 of the terminal block 6 one-to-one (see FIG. 2B). The terminal block 6 is housed within the body 20. The terminal block 6 is a four-pole screw type terminal block, and houses four contacts (not shown) in a rectangular parallelepiped main body 60 (see FIG. 3). Four terminal holes 66 are provided on the bottom surface (rear surface) of the main body 60. Further, four terminal screws 65 are arranged on the side surface (right side surface) of the main body 60. The terminal block 6 connects the contacts and the conductors electrically and mechanically by sandwiching the conductors of the electric wires inserted through each terminal hole between the terminal screws 65 and the contacts.

The rear end portion 201 of the body 20 has a width smaller in the left-right direction than the portions of the body 20 other than the rear end portion 201 (see FIGS. 2B and 2C). Four operation holes 202 are provided on the right side surface of the rear end portion 201 so as to be vertically aligned in a row (see FIG. 2D). These four operation holes 202 face one-on-one the heads of the four terminal screws 65 of the terminal block 6 housed in the rear end portion 201. That is, each terminal screw 65 of the terminal block 6 is rotated by a tool such as a screwdriver through each operation hole 202 of the rear end portion 201.

Furthermore, a plurality of slits 203 for heat radiation are formed on both left and right side surfaces of the body 20 (see FIGS. 2B, 2D, and 3). Further, triangular prism-shaped projections 204 are provided at the front ends of both upper and lower side surfaces of the body 20 (see FIG. 3).

The human body detection sensor 51 has a cylindrical case 510 (see FIG. 3). A square window 511 is opened at the front of the case 510. However, the window 511 is covered with a window plate 512 made of a material that can transmit infrared rays. A plurality of (for example, four) pyroelectric elements 513 are housed in the case 510 (see FIGS. 4 and 5). These plurality of pyroelectric elements 513 receive infrared rays that enter the case 510 through the window 511.

The human body detection sensor 51 is mounted at the center of the surface 500 of the second circuit board 50. The push button switch 52 is mounted on the lower part of the surface 500 of the second circuit board 50. Indicator lamp 54 is mounted on the top surface 500 of second circuit board 50 . The control circuit 53 is mounted on the surface 500 of the second circuit board 50 between the human body detection sensor 51 and the display lamp 54 .

The second circuit block 5 is housed in the body 20 with the surface 500 of the second circuit board 50 facing forward. The second circuit block 5 is arranged in front of the first circuit block 4 within the body 20 (see FIG. 4). Note that the first circuit block 4 and the second circuit block 5 are electrically connected via electric wires or terminal plates (not shown).

The cover 21 includes a cover body 210, a pair of vertical pieces 211, a pair of horizontal pieces 212, a pair of assembly pieces 213, and a vertical wall 214 (see FIG. 3). The cover main body 210 is formed into a rectangular frame shape with an opening 215 in the center.

The vertical wall 214 is formed into an octagonal cylindrical shape. The standing wall 214 protrudes forward along the edge of the opening 215 on the front surface of the cover body 210. Further, an operating piece 2141 projects upward from the lower surface of the vertical wall 214 facing the opening 215 (see FIG. 3). The operating piece 2141 is formed in a T-shape when viewed from the front and rear directions. The operating piece 2141 is supported by the standing wall 214 so as to be able to bend in the front-rear direction using the joint portion with the standing wall 214 as a fulcrum. Note that a cylindrical rib 2142 is integrally formed on the front surface of the operation piece 2141 (see FIG. 4).

The pair of vertical pieces 211 protrude forward from both left and right ends of the cover body 210, respectively (see FIG. 3). Each vertical piece 211 gradually becomes wider from both ends in the vertical direction toward the center (see FIG. 2D). A circular bearing hole 2110 is provided at the center of each vertical piece 211 in the longitudinal direction (vertical direction) (see FIG. 3). Note that a recess 2140 is formed in the vertical wall 214 at a portion facing the pair of bearing holes 2110.

The pair of horizontal pieces 212 protrude forward from both upper and lower ends of the cover body 210, respectively (see FIGS. 3 and 4). A pair of attachment claws 2120 protrudes upward from the upper surface of the upper horizontal piece 212. A pair of attachment claws 2120 also protrudes downward from the lower surface of the lower horizontal piece 212 (see FIGS. 2A and 3).

The pair of assembly pieces 213 protrude rearward from both upper and lower ends of the rear surface of the cover body 210 (see FIGS. 2D and 3). The pair of assembly pieces 213 are each formed into a rectangular shape (see FIG. 2C). A rectangular assembly hole 2130 penetrating in the thickness direction ( up and down direction) is provided in the center of each assembly piece 213 (see FIGS. 2C and 3).

The upper protrusion 204 of the body 20 fits into the assembly hole 2130 of the upper assembly piece 213 of the cover 21 . Furthermore, the protrusion 204 on the lower side of the body 20 fits into the assembly hole 2130 of the assembly piece 213 on the lower side of the cover 21 . That is, by fitting the pair of protrusions 204 of the body 20 one by one into the assembly holes 2130 of the pair of assembly pieces 213, the body 20 and the cover 21 are combined to form the container body 2 (FIGS. 2C and 2C). (see 4). Note that, on the front surface of the container body 2, the surface 500 of the second circuit block 5 is exposed through the opening 215 of the cover 21. Further, the rear surface of the rib 2142 of the cover 21 and the push button 520 of the push button switch 52 of the second circuit block 5 face each other (or are in contact with each other) along the front-rear direction (see FIG. 4).

The operating handle 3 includes a handle body 30, a handle cover 31, a lens unit 32, and an operating body 33 (see FIG. 3).

The frame portion 300 has a pair of vertical walls 3001 and a pair of horizontal walls 3002 and is formed into a truncated pyramid shape. However, it is preferable that the frame portion 300 is formed of a synthetic resin material that has substantially zero infrared transmittance and visible light transmittance (total light transmittance).

The first front wall 301 and the second front wall 302 are provided on the front surface of the frame portion 300, respectively. The first front wall 301 covers the front surface of the frame portion 300 from the upper horizontal wall 3002 to a position above the vertical center of the pair of vertical walls 3001. The second front wall 302 covers the front surface of the frame portion 300 from the lower horizontal wall 3002 to a position below the vertical center of the pair of vertical walls 3001. However, the length of the second front wall 302 in the vertical direction is approximately half the length of the first front wall 301 in the vertical direction. Thus, a quadrilateral window 303 surrounded by the lower edge of the first front wall 301, the upper edge of the second front wall 302, and the front edges of the pair of vertical walls 3001 is opened on the front surface of the frame portion 300.

The pair of protruding pieces 305 are formed in a semi-elliptical plate shape (see FIGS. 3 and 6). Each projecting piece 305 projects rearward from the vertical center of each vertical wall 3001. A cylindrical shaft 306 protrudes rightward from the right side surface of the right protruding piece 305. Further, a cylindrical shaft 306 projects leftward from the left side surface of the left projecting piece 305.

Note that the reinforcing bar 304, the pair of protrusions 305, and the pair of shafts 306 are preferably formed of a synthetic resin material that has substantially zero infrared transmittance and total light transmittance, similarly to the frame portion 300.

The operating body 33 is composed of a coil spring. One end (front end) of the operating body 33 in the longitudinal direction (in the axial direction of the coil spring) is fitted into and held by the holding portion 3020 of the handle body 30 (see FIG. 4).

The lens unit 32 has a base portion 320 and a plurality of lenses 321. The base portion 320 is formed into a rectangular plate shape. However, a peripheral wall 322 that protrudes rearward is integrally formed on the peripheral edge of the rear surface of the base portion 320 (see FIG. 4).

A plurality of lenses 321 (10 in the illustrated example) are integrally formed on the rear surface of the base portion 320 (see FIGS. 4 to 7). However, in the following description, the ten lenses 321 may be referred to as first to fifth lenses 321A to 321E and sixth to tenth lenses 321F to 321J.

The first to fifth lenses 321A to 321E are arranged in a line in the left-right direction. The third lens 321C in the center is a part of a Fresnel lens (see FIG. 7). The first lens 321A, the second lens 321B, the fourth lens 321D, and the fifth lens 321E are pseudo Fresnel lenses in which a plurality of elliptical grooves having different major and minor axes are arranged in a nested manner. is formed. The first to fifth lenses 321A to 321E are configured to condense infrared light incident from the front onto a focal point behind the third lens 321C.

The sixth to tenth lenses 321F to 321J are arranged in a row in the left-right direction below the first to fifth lenses 321A to 321E. The eighth lens 321H in the center is a part of a Fresnel lens (see FIG. 7). The sixth lens 321F, the seventh lens 321G, the ninth lens 321I, and the tenth lens 321J have a plurality of semi-elliptical or quarter-elliptic grooves nested in each other with different major and minor axes. They are arranged in a shape to form a pseudo Fresnel lens. The sixth to tenth lenses 321F to 321J are configured to condense infrared light incident from the front onto the focal point of the third lens 321C.

Note that the base portion 320, the ten lenses 321, and the peripheral wall 322 are preferably formed of a synthetic resin material whose infrared ray transmittance and total light transmittance are each several tens of percent (for example, 80%) or more. However, if the infrared transmittance of the synthetic resin material forming the lens 321 is several tens of percent (for example, 80%) or more, the infrared transmittance of the synthetic resin material forming the base portion 320 may be several percent or less. I don't mind.

The lens unit 32 is attached to the front surface of the handle body 30 by inserting a plurality of lenses 321 into the window 303 (see FIGS. 3 to 6). Note that cylindrical protrusions 323 are provided on the rear surface of both the upper and lower ends of the peripheral wall 322 (FIG. 7). These protrusions 323 are fitted into recesses 3003 (see FIG. 3) provided on the front surfaces of the pair of horizontal walls 3002 of the frame section 300. Thus, the lens unit 32 is positioned in the frame 300 of the handle body 30 by fitting each of the plurality of protrusions 323 into the plurality of recesses 3003 one by one.

With respect to the window 303, the first to fifth lenses 321A to 321E are inserted above the reinforcing bar 304, and the sixth to tenth lenses 321F to 321J are inserted below the reinforcing bar 304 (see FIG. 8). ). The reinforcing bar 304 is in contact with a portion between the first to fifth lenses 321A to 321E and the sixth to tenth lenses 321F to 321J on the rear surface of the base portion 320 (see FIG. 4). In other words, the reinforcing bar 304 can suppress deformation (deflection) of the lens 321 when the operating handle 3 is pressed by a person's hand or finger.

The handle cover 31 is formed into a rectangular plate shape (see FIG. 3). The handle cover 31 is attached to the front of the lens unit 32 (see FIG. 4). The handle cover 31 prevents dirt from adhering to the front surface of the lens unit 32 and from scratching the front surface of the lens unit 32. The handle cover 31 is made of a synthetic resin material (for example, polyolefin-based material) having an infrared transmittance of several tens of percent (for example, 90%) or more and a total light transmittance of several tens of percent (for example, 30%) or less. It is preferable that it is made of a resin material).

The operating handle 3 is attached to the container body 2 so as to cover the front surface of the container body 2 by fitting the pair of shafts 306 of the handle body 30 one by one into the pair of bearing holes 2110 of the cover 21 (see FIGS. 4 to 4). (see 6). The operating handle 3 is rotatable about a pair of shafts 306 as fulcrums. However, the rib 2142 of the cover 21 is fitted into the other end (rear end) of the operating body 33 in the longitudinal direction (in the axial direction of the coil spring) (see FIG. 4). Therefore, the operating handle 3 is pushed by the spring force of the operating body 33 in a direction to move the lower part of the handle body 30 away from the front surface of the container body 2, and the upper part (upper side wall 3002) of the handle body 30 is pushed to the upper side of the cover 21. It stops at the position where it hits the piece 212 (reference position) (see FIG. 4).

When the lower part of the operating handle 3 is pushed backward, the operating handle 3 rotates (forward rotation) in a direction that brings the lower part of the handle body 30 closer to the front of the container body 2. As the operating handle 3 rotates, the operating piece 2141 of the cover 21 receives the spring force of the operating body 33 and bends backward. As the operation piece 2141 bends backward, the push button 520 of the push button switch 52 is pushed by the operation piece 2141, and the push button switch 52 is turned on. When the lower part of the operating handle 3 is no longer pressed, the operating handle 3 rotates (reversely rotates) due to the spring force of the operating body 33 and returns to the standard position, and the operating piece 2141 also returns to its original state, causing the pushbutton Switch 52 is turned off.

Furthermore, a human body detection sensor 51 is present inside the window 303 of the handle body 30 of the operating handle 3 when viewed from the front (see FIG. 8). Therefore, the human body detection sensor 51 can detect the human body by receiving infrared rays emitted from the human body through the handle cover 31 and the window 303 of the handle body 30.

Therefore, by hiding the human body detection sensor 51 behind the operation handle 3, the switch device 1 can reduce the size of the operation handle 3 compared to a case where the operation handle 3 and the human body detection sensor 51 are arranged vertically or horizontally. It is possible to downsize without making any changes. As a result, the switch device 1 can be made smaller while suppressing a decrease in operability (of the operating handle 3).

Here, when the operating handle 3 is stationary at the reference position, the third lens 321C and the window 511 of the case 510 of the human body detection sensor 51 overlap in the horizontal and vertical directions (see FIG. 8). Furthermore, when the operating handle 3 is stationary at the reference position, the focal point of the third lens 321C almost coincides with the light receiving surface of the human body detection sensor 51 (the front surface of the window plate 512) in the front-back direction (see FIG. 4). . Therefore, infrared rays emitted from a human body existing within the detection area can be focused (converged) on the window 511 of the human body detection sensor 51 by the plurality of lenses 321. As a result, the switch device 1 can expand the detection area of the human body detection sensor 51.

Further, in the switch device 1, by shielding unnecessary infrared rays by the first front wall 301 and the second front wall 302 of the handle body 30, it is possible to suppress the occurrence of false detection by the human body detection sensor 51. In particular, in the switch device 1, the light receiving surface (window 511) of the human body detection sensor 51 is arranged above the vertical center position (position of the reinforcing bar 304) of the window 303 of the handle body 30 (FIG. reference). Therefore, in the switch device 1, for example, infrared rays included in the illumination light of the lighting device are less likely to enter the light receiving surface of the human body detection sensor 51, so that the occurrence of false detection by the human body detection sensor 51 can be further suppressed.

Further, in the switch device 1, by forming a detection area by a plurality of detection ranges corresponding one-to-one with each of the plurality of lenses 321, the human body detection sensor 51 can detect slight movements of the human body. As a result, the switch device 1 can reduce the possibility of not detecting a person (human body) staying within the detection area.

Here, since the total light transmittance of the synthetic resin material forming the handle cover 31 is several tens of percent or less, the human body detection sensor 51 is difficult to see through the operating handle 3. As a result, the switch device 1 can suppress deterioration in appearance quality due to the human body detection sensor 51 being seen through the operation handle 3.

By the way, the switch device 1 is disposed so as to be embedded in an embedding hole 80 provided in construction material (for example, wall material 8) using the mounting frame 7 (see FIG. 9). The mounting frame 7 is formed of a synthetic resin material into a rectangular frame shape having a window hole 70 in the center. The mounting frame 7 has a pair of side pieces 71 facing each other with a window hole 70 in between. Each of the pair of side pieces 71 is provided with a mounting hole 72 into which a plurality of (four) mounting claws 2120 of the container body 2 are respectively fitted.

By fitting each of the four mounting claws 2120 into the four mounting holes 72 one by one, the switch device 1 is mounted on the mounting frame 7 with the device body 2 inserted through the window hole 70 (Fig. 9 reference). Then, by fixing (screwing) the mounting frame 7 to the surface of the wall material 8 with a part of the device body 2 embedded in the embedding hole 80, the switch device 1 is embedded in the construction surface (wall surface). will be placed.

Note that in the switch device 1, the human body detection sensor 51 is not limited to a passive infrared motion sensor. For example, the human body detection sensor 51 may be an active radio wave sensor that uses radio waves in the millimeter wave band.

Next, some modified examples of the switch device 1 will be described with reference to the drawings. However, the switch device 1 of the modified example described below has the same basic configuration as the switch device 1 of the embodiment described above. Therefore, the same reference numerals are given to the same components as those in the switch device 1 of the embodiment, and illustration and description thereof will be omitted.

First, the switch device 1 of Modification 1 will be explained. As shown in FIG. 10, the switch device 1 of the first modification includes two detection sections: a human body detection sensor 51 and a brightness sensor 55.

The brightness sensor 55 detects the amount of light (brightness) received by the light receiving element by converting visible light into an amount of electricity (for example, current) using a light receiving element such as a photodiode or a phototransistor. The output (output current) of the brightness sensor 55 is converted into a voltage (detected voltage) by a current/voltage converter (not shown) and input to the input port (third input port) of the control circuit 53.

The control circuit 53 compares the detected voltage input to the third input port with a predetermined threshold. When the detection voltage is equal to or higher than the threshold value, the control circuit 53 does not perform a control operation even if the human body detection signal is input to the first input port. When the detection voltage is less than the threshold value, the control circuit 53 performs a control operation when the human body detection signal is input to the first input port. That is, when the detected voltage is equal to or higher than the threshold value, the control circuit 53 determines that there is no need to light up the lighting load W1, ignores the input of the human body detection signal, and does not perform any control operation. On the other hand, when the detected voltage is less than the threshold value, the control circuit 53 switches the lighting load W1 from the off state to the on state when the human body detection signal is input. However, the switch device 1 of the first modification may include only the brightness sensor 55 without the human body detection sensor 51. Note that the brightness sensor 55 is preferably mounted on the surface 500 of the second circuit board 50 of the second circuit block 5.

As described above, the switch device 1 of Modification 1 saves energy by not lighting up the lighting load W1 unnecessarily when the brightness detected by the brightness sensor 55 does not require lighting the lighting load W1. I can do it.

Next, the switch device 1 of Modification 2 will be explained. In the switch device 1 of the second modification, the operation handle 3 is rotatable between two positions: an off position (see FIG. 11A) and an on position (see FIG. 11B). The operating handle 3 rotates to the on position when manually operated from the off position, and rotates to the off position when manually operated from the on position.

Two reversing springs 10 (only one is shown) and two reversing plates 11 (only one is shown) are arranged between the operating handle 3 and the front surface of the device body 2 (FIGS. 11A and 11). 11B). Each reversal plate 11 is accommodated in a V-shaped groove 205 provided in the vessel body 2. Each reversing spring 10 is made of a coil spring. One axial end (front end) of each reversing spring 10 is fixed to the handle body 30. The other axial end (rear end) of each reversing spring 10 is hooked onto the front end of the reversing plate 11. The rear end of each reversing plate 11 is pressed against the bottom 206 of the groove 205 by the spring force of each reversing spring 10 . Note that each reversing plate 11 is rotatable in the vertical direction using the rear end that is in contact with the bottom 206 as a fulcrum.

Therefore, when the operating handle 3 is in the off position, the upper part of the frame 300 of the handle body 30 (upper side wall 3002) hits the front surface of the container body 2, and the operating handle 3 comes to rest in the off position (see FIG. 11A). ). When the operating handle 3 in the off position is pressed, the operating handle 3 rotates while compressing the reversing spring 10. As the operating handle 3 rotates, the reversing plate 11 also rotates, and the lower part (lower side wall 3002) of the frame 300 of the handle body 30 hits the front of the device body 2, causing the operating handle 3 to stop at the on position. (See FIG. 11B).

As described above, in the switch device 1 of the second modification, when the operation handle 3 is in the on position, the control circuit 53 can ignore the human body detection signal of the human body detection sensor 51 and maintain the lighting load W1 in the lighting state. can. On the other hand, when the operation handle 3 is in the off position, in the switch device 1 of the second modification, the control circuit 53 can cause the lighting load W1 to blink in response to the human body detection signal of the human body detection sensor 51.

Finally, the switch device 1 of Modification 3 will be explained. The switch device 1 of the third modification is configured such that the operating handle 3 moves in parallel in the front and back direction with respect to the front surface of the device body 2.

At least one return spring 12 is disposed between the upper and lower ends of the operating handle 3 and the front surface of the device body 2, respectively (see FIG. 12). The return spring 12 is made of a coil spring. One axial end (front end) of the return spring 12 is fixed to the handle body 30. The other axial end (rear end) of the return spring 12 is fixed to the front surface of the container body 2. Note that the bearing hole 2110 of the cover 21 is formed in an oval shape whose longitudinal direction is the front-rear direction.

The operating handle 3 is pushed away from the front surface of the device body 2 (in the forward direction) by the spring force of the return spring 12, and comes to rest at a position (reference position) where the shaft 306 hits the front end of the bearing hole 2110 (Fig. 12 reference). When the operating handle 3 is pushed, the operating handle 3 moves rearward while compressing the return spring 12, and the push button switch 52 is turned on via the operating body 33 and the operating piece 2141 (both not shown). When the operating handle 3 is no longer pressed, the operating handle 3 returns to its reference position by the spring force of the return spring 12.

As described above, in the switch device 1 of the third modification, the operation handle 3 can be operated like a push button. Note that the operating handle 3 may be configured to be slid in parallel to the front surface of the vessel body 2. Alternatively, the operating handle 3 may be configured to be rotated about an axis perpendicular to the front surface of the vessel body 2. Further, a touch switch may be provided on the surface of the operating handle 3, and the control circuit 53 may turn on and off the opening/closing element 41 by a touch operation on the touch switch. Note that if the human body detection sensor is miniaturized, it will be possible to incorporate the human body detection sensor into the operation handle 3.However, it is possible to incorporate the human body detection sensor 51 illustrated in the embodiment into the operation handle 3. I can't.
