The above described features and advantages of the present invention will be more apparent from the following description.

Hereinafter, an embodiment in which the switch device of the present invention is embodied will be described with reference to the drawings. In the following description, the "front-rear direction", the "left-right direction", and the "up-and-down direction" refer to the directions indicated by the directions indicated by the arrows in the respective drawings.

(First embodiment)

Hereinafter, the switch device 11 according to the first embodiment of the present invention will be described.

As shown in FIGS. 1 and 2, the switch device 11 includes a housing 14 including a back cover box body 12 made of a synthetic resin material, and the same synthetic resin material and covering the body 12. Open cover 13 . On the front surface side of the casing 14, a fixing frame 15 made of a metal material for an embedded wiring device having a specification such as JIS or the like is attached. Further, the switch device 11 is fixed to a building material (for example, a wall surface or the like) via the fixing frame 15.

As shown in Fig. 1, on the front surface side of the cover plate 13, a piano handle type operation handle 16 made of a synthetic resin material is attached and detachable. Further, as shown in FIG. 2, the shaft portion 17 is provided at a position near the center in the vertical direction on the left end side of the cover plate 13. The operation handle 16 is rotatably supported by the axial direction of the shaft portion 17 of the cover plate 13, thereby being supported in a state of being swingable with respect to the casing 14.

A locking groove 18 (see FIG. 2) is formed on the right end side of the cover plate 13. On the other hand, on the right end side of the operation handle 16, a locking piece 16a (refer to FIG. 1) that can be locked with the locking groove 18 is protruded rearward. Further, the swinging range of the operating handle 16 is defined by locking the locking piece 16a of the operating handle 16 in the locking groove 18 of the cover plate 13. Further, on the front surface side of the operation handle 16, a projection 19 (see FIG. 1) for indicating the pressing operation position of the operation handle 16 is formed at a position shifted to the right side in the vicinity of the center in the vertical direction.

An elastic member (for example, a leaf spring) (not shown) is disposed between the cover plate 13 and the operating handle 16 in the vicinity of the shaft portion 17. When the pressing operation is performed on the vicinity of the projection 19 of the operation handle 16 toward the rear, the operation handle 16 is rotated rearward about the left end side, and the elastic member is elastically deformed. Therefore, when the pressing force accompanying the pressing operation is released, the operation handle 16 is rotated forward along the left end side in accordance with the return deformation of the elastic member, and is returned to the original position.

As shown in Fig. 1, on the operation handle 16, the opening window 20 is formed at a position shifted to the left side in the vicinity of the center in the vertical direction. On the other hand, as shown in FIG. 2, on the cover plate 13, the opening window 21 is provided at a position corresponding to the opening window 20 of the operation handle 16, and the opening window 22 is provided near the lower side of the opening window 21.

Further, on the cover plate 13, an operation piece 23 of a substantially T-shape is cut and formed on the right side of the opening window 21. In the operation piece 23, the arm portion 23a extending in the left-right direction is elastically deformable in the front-rear direction, and the front end side of the arm portion 23a is a pressing portion 23b extending in the vertical direction.

Further, on the cover plate 13, the operation piece 24 extending in the vertical direction is cut to the right of the opening window 22. In the operation piece 24, the arm portion 24a extending in the vertical direction is elastically deformable in the front-rear direction, and the front end portion of the arm portion 24a is a pressing portion 24b having a substantially cylindrical shape. Further, the pressing portion 23b of the operation piece 23 is formed to protrude further forward than the pressing portion 24b of the operation piece 24.

When the pressing operation is performed on the vicinity of the projection 19 of the operation handle 16 toward the rear, the pressing portion 23b of the operation piece 23 receives the pressing force of the operating handle 16. Thereby, the arm portion 23a is elastically deformed so that the pressing portion 23b is displaced rearward. On the other hand, the operation piece 24 is not displaced by the pressing operation of the operation handle 16. When the operation handle 16 is removed from the cover 13 and the pressing portion 23b is pressed rearward, the arm portion 24a is elastically deformed. When the pressing operation is released to the operation pieces 23 and 24, the arm portions 23a and 24a are deformed in a return manner, so that the pressing portions 23b and 24b are returned to their original positions.

Next, the electrical configuration of the switching device 11 will be described with reference to Fig. 3 .

As shown in FIG. 3, the switching device 11 includes display lamps 25 and 26 composed of light-emitting diodes, an operation switch 27, a registration button 28, and a microcomputer (microcomputer) as a main component. The control unit 30, the load control unit 31, the wireless signal transmission/reception unit 32 as a reception unit, an antenna 33, a storage unit 34, and a power supply unit 35. Further, the display lamps 25 and 26, the operation switch 27, the registration button 28, and the like are mounted on a print substrate (not shown) housed in the casing 14.

The load control unit 31 includes a switching element SW (for example, a relay or a semiconductor switching element) that is inserted into a power supply circuit that is mounted from a power source AC that is a commercial AC power source to a lighting load L that is a load. According to the radio wave method, the "determined low-power radio station for telemeter, tele-control, and data transmission" specified in Rule 6, Item 4, No. 2, the wireless signal transmitting and receiving unit 32 is via the radio signal transmitting and receiving unit 32. The antenna 33 transmits and receives a wireless signal in which a radio wave is a medium. The power supply unit 35 receives power from the power source AC to generate an operating power supply for each part. Furthermore, in the present embodiment, the control unit 30 and the load control unit 31 constitute a control unit, and the switching element SW constitutes an opening and closing unit.

When the operation handle 16 is pressed, the operation piece 23 of the cover 13 is displaced rearward, and the pressing portion 23b presses the operation portion (not shown) of the operation switch 27. Then, the operation switch 27 that is pressed by the operation piece 23 outputs an operation signal from an OFF state in which the circuit is not connected to an ON state in which the circuit is connected. Further, when the pressing operation of the operation handle 16 is released, the operation piece 23 is returned to the original position, so that the pressing operation of the operation switch 27 is released.

In the normal mode as the first mode, the control unit 30 performs opening and closing control of the switching element SW based on the operation signal output from the operation switch 27 or the wireless signal received by the wireless signal transmission/reception unit 32. Specifically, the control unit 30 outputs a control signal, and the load control unit 31 causes the switching element SW to be driven to open and close based on the control signal, and opens and closes the power supply circuit for the illumination load L.

For example, when the wireless signal transmitting/receiving unit 32 receives the wireless signal when the power supply circuit is in the closed state, the control unit 30 causes the switching element SW to be driven to be turned on via the load control unit 31, thereby making the power supply circuit for the illumination load L Disconnected state. Further, similarly, when the power supply circuit is in the closed state, when the operation handle 16 is short-pressed, the control unit 30 causes the switching element SW to be driven to be turned on via the load control unit 31 based on the operation signal, thereby causing the illumination load L to be turned on. The power supply circuit is turned off.

In the present embodiment, the short pressing operation means that the pressing operation time Tp from the start of the pressing operation to the release is smaller than a predetermined predetermined time Ts (Ts = pressing operation release time t2 - pressing operation start time t1) On the other hand, the pressing operation in which the pressing operation time Tp is equal to or longer than the predetermined time Ts is referred to as a long pressing operation. Further, the predetermined time Ts may be, for example, 1 to 2 seconds, but may be set to an arbitrary length.

Then, when the power supply circuit is turned off, the lighting load L is turned on (ON) when the lighting load L is supplied from the power source AC. On the other hand, when the wireless signal transmitting/receiving unit 32 receives the wireless signal when the power supply circuit is in the off state, the control unit 30 causes the switching element to be driven off via the load control unit 31, thereby making the illumination load L The power supply circuit is in a closed state. Further, when the operation handle 16 is short-pressed when the power supply circuit is in the closed state, the control unit 30 transmits a control signal to turn off the illumination load L, and the load control unit 31 causes the switching element SW to be driven off, thereby enabling illumination. The power supply circuit of the load L is in a closed state. Further, when the wireless signal transmitting/receiving unit 32 receives the wireless signal when the power supply circuit is in the closed state, the power supply circuit can be made after the predetermined time elapses after the switching element SW is turned on and the illumination load L is turned on. Closed state. When the power supply circuit for the illumination load L is brought into a closed state, the illumination load L is turned off (OFF).

Further, when the illumination load L is turned on, the control unit 30 turns off the display lamp 25 as the first display state (OFF), while the control unit 30 causes the display lamp 25 to act as the illumination load L is turned off. The lighting state of the second display state (ON). Here, the display lamp 25 is disposed at a position corresponding to the opening window 21 of the cover 13 and the opening window 20 of the operation handle 16. Therefore, when the illumination load L is turned off, the light of the displayed display lamp 25 is irradiated toward the front through the opening windows 20 and 21.

In other words, the display lamp 25 displays the switching element SW in the off state in the off state in accordance with the open/close state of the switching element SW, and displays the switching element SW in the closed state by the lighting state. Moreover, the position of the operating handle 16 is displayed when the lighting load L is turned off by the display lamp 25 being turned on.

Further, in the switch device 11 of the present embodiment, when the operation handle 16 is long-pressed for a predetermined time Ts or more in the normal mode, the control unit 30 will automatically operate from the operation signal accompanying the short press operation or wirelessly. The normal mode in which the signal is subjected to the opening and closing control of the switching element SW is converted into a prohibition mode as the second mode in which the opening and closing control of the switching element SW is not performed based on the wireless signal.

Further, in the present embodiment, the prohibition mode of the control unit 30 is released by the short-press operation of the operation handle 16 and is switched to the normal mode, but may be converted to the normal mode by the long-press operation of the operation handle 16. .

In the prohibition mode, the control unit 30 switches the turning on and off of the display lamp 25 at a fixed cycle, and causes the display lamp 25 to be different from any of the first display state and the second display state. The flashing status of the status is displayed. In other words, the display lamp 25 constitutes a display unit for displaying the control unit in the prohibition mode, and when the long-pressing operation is performed, the opening/closing control (wireless control) of the switching element SW based on the wireless signal is displayed to be invalid by the blinking state. .

As shown in FIG. 4, the switching device 11 of the present embodiment can turn on or off the illumination load L based on the wireless signal transmitted from the transmitting unit, thereby configuring the load control system. The transmitting unit is embodied to be, for example, a fire reporter 50A, 50B, 50C that senses a fire and issues an alarm, an operation terminal 51 for remotely operating the lighting load L, or a configuration with the internal telephone extension 52. The inbound telephone host 53 of the internal telephone system, and the like.

In the switching device 11, the wireless signal to be received by the wireless signal transmitting and receiving unit 32 is specified by assigning an ID number and registering the transmitting unit. Further, when a new transmission unit is registered, the operation handle 16 is detached from the cover 13 and the pressing portion 24b of the operation piece 24 is subjected to a long press operation for a predetermined time or longer (for example, 2 seconds or more). Thereby, the operation piece 24 shifted to the rear performs a pressing operation on the operation portion of the registration button 28.

When the registration button 28 is pressed, the operation mode of the control unit 30 is switched to the registration mode, and the display lamp 26 is turned on. Here, the display lamp 26 is disposed at a position corresponding to the opening window 22 of the cover plate 13, so that if the display lamp 26 is turned on, the light of the display lamp 26 will be irradiated to the front through the opening window 22, and the control portion is displayed. 30 has been converted to registration mode. Further, when the pressing operation is released, the operation piece 24 is returned to the original position, and the pressing operation of the registration button 28 is also released.

After that, when the wireless signal transmitting/receiving unit 32 receives the wireless signal to be transmitted from the transmitting unit, the control unit 30 stores the ID number included in the wireless signal in the memory unit 34 as the transmitting unit that allocates itself. Further, when the registration of the transmission unit is completed, the display unit 26 is turned off by pressing the operation sheet 24 again, and the control unit 30 switches from the registration mode to the original operation mode (for example, Normal mode).

Next, the operation of the switch device 11 including the operation terminal 51 for detecting a human body sensor and the load control system will be described.

At this time, when the operation terminal 51 detects a person in the detection area of the human body sensor, a wireless signal is transmitted, and when the wireless signal transmission/reception unit 32 receives the wireless signal, the control unit 30 transmits the wireless signal via the load control unit. 31 causes the switching element SW to be driven to be turned on, thereby lighting the illumination load L. Therefore, by arranging, for example, the switch device 11 and the lamp as the illumination load L near the center of the room, and setting the detection area of the human body sensor near the entrance of the room, it is possible to wirelessly control when the person enters the room. And make the light light. Further, by performing a short press operation on the operation handle 16 of the switch device 11, the lamp can be turned off or lighted according to an operation signal output from the operation switch 27.

Here, for example, when it is desired to maintain the lighting state of the lighting load L when the lamp is replaced, or when the lighting state of the lighting load L is to be maintained during the cleaning, the previous switching device is, for example, from the operation terminal 51. When a wireless signal including load control information is transmitted, the state of the lighting load L is switched, and thus there is a fear of the operator. Therefore, in the switching device 11 of the present embodiment, the operation mode of the control unit 30 can be switched to the prohibition mode for prohibiting the load control of the wireless signal, and the operation switch 27 can be operated by a predetermined time (for example, 2 seconds). Actually, the operation handle 16) is long pressed and switched to the prohibition mode. Further, when the operation mode of the control unit 30 is switched to the disable mode, load control of wireless signals from various transmitting units is performed. The system will be disabled, and as a result, the state of the lighting load L can be maintained. Furthermore, the above-described prohibition mode can be released by pressing the operation handle 16 again.

5 is a timing chart for explaining the operation of the switching device 11 of the present embodiment. When the operation switch 27 is long pressed for a predetermined time Ts or longer and the operation mode of the control unit 30 is switched to the prohibition mode, the lighting load is applied. L is forcibly switched to the lighting state or the extinguishing state. As shown in Fig. 5, in the present embodiment, the lighting load L is forcibly switched to the extinguishing state (after time t2 in the figure). Further, at this time, since the illumination load L is in the extinguished state, the display lamp 25 is switched to the lighting state to display the position of the switching device 11. Further, the lighting/extinguishing state of the lighting load L when switching to the prohibition mode can be selectively switched by, for example, a switching unit not shown.

Here, in general, since the load is controlled by the switching edge of the signal when the operation portion of the operation switch 27 is pressed (that is, the pressing operation is performed on the operation handle 16) (refer to FIG. 5(a)), When the operation mode of the control unit 30 is switched to the prohibition mode, the illumination load L is temporarily switched to the lighting state at the time t1 when the operation unit of the operation switch 27 is pressed, and the operation mode of the control unit 30 is elapsed after the predetermined time Ts elapses. When the mode is switched to the prohibition mode (the time point of time t2 in FIG. 5(a)), the illumination load L is forcibly switched to the extinguished state. In other words, at this time, the illumination load L performs an unnecessary lighting/extinguishing operation during the period from the operation of the operation switch 27 to the prohibition mode, and the user feels uncomfortable.

On the other hand, as shown in FIG. 5(b), when the load is controlled in accordance with the switching edge of the signal when the operation portion of the operation switch 27 is released (that is, when the operation handle 16 is released), even if, for example, the time t1 is pressed. In the operation unit of the operation switch 27, the illumination load L is maintained in the current state (ie, the off state), and the operation mode of the control unit 30 is switched to the prohibition mode when the predetermined time Ts elapses (the time in FIG. 5(b) At the time point of t2), in the example shown in FIG. 5(b), the illumination load L is still in the extinguished state, and thus the extinguished state is maintained. Further, when the operation portion is released before the predetermined time Ts elapses after the operation portion of the operation switch 27 is pressed, the prohibition mode is not switched, the illumination load L is turned on, and the display lamp 25 is turned off (ie, performed). Normal lighting/extinguishing action).

Here, when the operation mode of the control unit 30 is switched to the prohibition mode at time t2, as shown in FIG. 5(b), the display lamp 25 is slowly blinked at a predetermined cycle (for example, 0.25 Hz), and the user can confirm by The display of the display lamp 25 is known to switch to the disable mode. Here, in the present embodiment, the display unit 25 constitutes a display unit.

Further, according to the present embodiment, by prohibiting the load control of the wireless signal, it is possible to prevent the load state from being switched by the operation of the transmitting unit, for example, when the lamp is replaced or during the cleaning, and as a result, the operator can perform the work with peace of mind. Further, since the operation switch can be switched to the prohibition mode by long pressing 27, it is not necessary to separately provide a unit for switching to the prohibition mode, and cost up can be suppressed, and the operation becomes easy. Further, since the operation can be switched to the prohibition mode by one operation and the illumination load L can be extinguished (or lit) regardless of the load state, the operation can be saved in time and effort, and as a result, the operability can be improved.

Further, when the operation mode of the control unit 30 is switched to the prohibition mode, the state of the illumination load L can be maintained from the time when the operation portion of the operation switch 27 is pressed until the prohibition mode is set, so that, for example, the operation will be pressed. When the signal at the operation portion of the switch 27 is an operation signal, there is no unnecessary lighting/extinguishing operation until the standby mode is set, and as a result, unnecessary flashing/extinguishing operation can be avoided. Discomfort. Further, it is possible to easily confirm whether or not the display mode is set to the prohibition mode by the display lamp 25 (display unit). Therefore, the switch device 11 which is easy to use can be realized, and the display lamp 25 can be separately turned on and blinked to perform the following two steps. In other words, the display when the illumination load L is in the off state and the display when the operation mode of the control unit 30 is switched to the prohibition mode are displayed. Therefore, since it is not necessary to separately provide the display unit, the cost increase can be further suppressed.

Further, in the present embodiment, the display unit 25 for position display functions as a display unit for switching the operation mode of the control unit 30 to the prohibition mode, but a display lamp different from the display lamp 25 may be provided as the above. Display unit. Further, the first to third display states can be realized by changing the color, the light-emitting intensity, or the pattern of the display lamp.

The display unit may be a display lamp using an illumination device other than the light-emitting diode, and may be a buzzer that reports by sound or a liquid crystal that displays a notification content by text information or a mark. A panel or the like can also be a notification unit.

Further, in the present embodiment, the operation handle 16 for pressing the operation switch 27 is provided. However, it is not necessary to provide the operation handle, and the pressing portion 23b can be directly pressed, for example.

Further, in the present embodiment, the case where the radio wave is a radio signal of the medium has been described as an example. However, the present embodiment is not limited to a radio signal, and for example, the light may be a medium. In addition, the time during which the operation switch 27 is long pressed when switching to the prohibition mode may be appropriately set according to specifications or the like.

(Second embodiment)

Hereinafter, the switch device 11 according to the second embodiment of the present invention will be described. This embodiment is the same as the basic configuration of the first embodiment, and differs in the operation of the illumination load L and the display lamp 25 by the operation of the operation switch 27. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and their description is omitted.

In the switch device 11 of the present embodiment, when the operation handle 16 is long-pressed by the predetermined time Ts or more in the normal mode, the control unit 30 performs the switching element from the operation signal or the wireless signal accompanying the short-press operation. The normal mode of the opening and closing control of the SW is converted into a prohibition mode as the second mode in which the opening and closing control of the switching element SW is not performed based on the wireless signal, and the opening and closing state of the switching element SW is reversed from the state before the long pressing operation. Therefore, when the operation handle 16 is long-pressed when the illumination load L is turned off, the illumination load L is turned on, and when the operation handle 16 is long-pressed when the illumination load L is turned on, the illumination load L is turned off.

Here, in a normal mode in which load control of the illumination load L can be performed not only by an operation signal accompanying a short press operation but also by a wireless signal, although it is desirable to maintain the power supply circuit in a closed state for, for example, replacing the lamp, Sometimes a wireless signal is transmitted in the detection area to detect the presence of another person, causing the power supply circuit to be turned off.

At this time, by performing a long press operation on the operation handle 16 of the switch device 11, the control unit 30 is switched to the prohibition mode, so that the wireless signal becomes invalid, and the lamp is maintained in the state before the long press operation, that is, the extinguished state. Thereby, until the operation of the operation handle 16 is performed next time, the open/close state of the power supply circuit is not changed by the wireless signal, and the operator can safely perform the lamp replacement operation. Further, when the control unit 30 is in the disable mode, since the display lamp 25 blinks, it is easy to visually recognize that the wireless signal is invalid.

Further, for example, in the normal mode, although the operator outside the detection area of the human body sensor wants to keep the lighted state of the lamp, the power supply circuit may be closed due to the fact that others in the detection area are outside the detection area. status. At this time, after the operator who wants to keep the lighting state lights up the lighting load L, the control unit 30 is switched to the prohibition mode by performing a long press operation on the operation handle 16, so that the wireless signal becomes invalid, and the light is turned on. Keep it lit before the long press operation. Thereby, the wireless control is not performed until the operation of the operation handle 16 is performed next time, and the operator can perform the work in the original state of the desired lighting state.

Next, an operation sequence of the switching device 11 according to the second embodiment of the present invention will be described with reference to Fig. 6 .

First, a case where the operation handle 16 is short-pressed when the illumination load L is in the OFF state and the display lamp 25 is in the ON state in the normal mode will be described.

As shown in FIG. 6(a), when the operation of the operation switch 27 is started via the operation handle 16 and the operation piece 23 at time t1, the operation switch 27 starts outputting an operation signal. Thereby, the control unit 30 detects the switching edge when the operation signal is started to be output, and counts (counts) the output time of the operation signal, that is, the pressing operation time Tp. Then, the control unit 30 compares the counted pressing operation time Tp with the predetermined time Ts at a predetermined interval to determine whether or not the pressing operation time Tp exceeds the predetermined time Ts.

Then, when the pressing operation of the operation switch 27 is released at the time tr (t1 < tr < t2), the operation switch 27 ends the output of the operation signal. Further, the control unit 30 detects the switching edge at the end of the output of the operation signal, and ends the counting of the pressing operation time Tp. Thus, since the pressing operation time Tp at the end of counting is smaller than the predetermined time Ts (Tp<Ts), the control unit 30 determines that the pressing operation of the operating handle 16 is a short pressing operation, and outputs the control signal to cause the switching element SW. The open/close state is reversed, and the display lamp 25 is switched from the ON state to the OFF state. As a result, the illumination load L in the extinguished state is turned on, and the display lamp 25 in the turned-on state is turned off.

On the other hand, when the illumination load L is in the ON state and the display lamp 25 is in the OFF state, the operation handle 16 is short-pressed in the same manner, the illumination load L is turned off, and the display lamp 25 is turned on.

Next, a case will be described in which the operation handle 16 is long-pressed when the illumination load L is in the OFF state and the display lamp 25 is in the ON state in the normal mode.

As shown in FIG. 6(b), when the pressing operation of the operation switch 27 is started via the operation handle 16 and the operation piece 23 at time t1, the operation switch 27 starts outputting an operation signal. Thereby, the control unit 30 detects the switching edge when the operation signal is started to be output, and counts the pressing operation time Tp.

When the pressing operation time Tp exceeds the predetermined time Ts (Tp ≧ Ts), the control unit 30 determines that the pressing operation of the operating handle 16 is a long-pressing operation, thereby shifting to the prohibition mode, and maintaining the opening and closing state of the switching element SW as Long press the off state before the operation, and the display lamp 25 is blinked. Thereby, the illumination load L in the extinguished state continues to remain in the extinguished state, and the display lamp 25 in the lit state becomes the blinking state.

Next, a case will be described in which the operation handle 16 is long-pressed when the illumination load L is in the ON state and the display lamp 25 is in the OFF state in the normal mode.

As shown in FIG. 6(c), when the pressing operation of the operation switch 27 is started via the operation handle 16 and the operation piece 23 at time t1, the operation switch 27 starts the output of an operation signal. Thereby, the control unit 30 detects the switching edge when the operation signal is started to be output, and counts the pressing operation time Tp.

When the pressing operation time Tp exceeds the predetermined time Ts (Tp ≧ Ts), the control unit 30 determines that the pressing operation of the operating handle 16 is a long pressing operation, thereby shifting to the prohibition mode, and maintaining the opening and closing state of the switching element SW as Long press the on state before the operation, and the display lamp 25 is blinked. Thereby, the lighting load L in the lighting state continues to be in the lighting state, and the display lamp 25 in the extinguishing state is in the blinking state.

As described above, in the normal mode, when the pressing operation time Tp is smaller than the predetermined time Ts, the control unit 30 outputs a control signal for inverting the opening and closing state of the switching element SW, and the pressing operation time Tp is equal to or greater than When the time Ts is specified, the control unit 30 does not output a control signal for inverting the open/close state of the switching element SW, but converts it to the prohibition mode.

When, for example, when the control unit 30 detects the switching edge when the operation signal is started to be output, that is, when the pressing operation of the operation unit is started, the control unit 30 outputs a control signal to reverse the opening and closing state of the switching element SW, and the operation is performed during the long press operation. Since the open/close state of the switching element SW is maintained in the state before the long press operation, the switching element SW is driven to open and close at time t1 and time t2. In other words, since the unnecessary lighting and the extinguishing are performed until the transition to the prohibition mode, the user feels uncomfortable.

In response to this, the switching device 11 of the present embodiment controls the opening and closing of the switching element SW after determining whether the pressing operation is a short pressing operation or a long pressing operation. Therefore, it is possible to prevent the lighting load L from being excessively turned on and off. Improved operability.

According to the embodiment described above, the following effects can be obtained.

(1) Since the opening and closing control of the switching element SW and the conversion of the control unit 30 to the prohibition mode can be performed via the shared operation unit, it is not necessary to provide a dedicated operation switch for the control unit 30 to be switched to the prohibition mode, so that it can be easily configured. The switching device 11 is implemented. Further, by the long press operation of the operation handle 16, the operation mode of the control unit 30 is switched from the normal mode to the prohibition mode in which the opening and closing control of the switching element SW is not performed based on the wireless signal, and the opening and closing state of the switching element SW is maintained as The state before the operation is long pressed, so that the load control based on the wireless signal can be made invalid, and the desired load state is maintained. Moreover, it is possible to switch to the prohibition mode without changing the load state, so that load control that is easy for the user to understand can be realized.

(2) When the pressing operation time Tp is less than the predetermined time Ts, the control unit 30 inverts the opening and closing state of the switching element SW. In other words, when the opening and closing state of the switching element SW is reversed immediately after the pressing operation of the operation unit is started, the opening and closing state is reversed again after the predetermined time Ts elapses during the long-press operation, and the unnecessary opening and closing control is performed. In this regard, in the present configuration, the control unit 30 controls the opening and closing of the switching element SW after confirming that the pressing operation time Tp is less than the predetermined time Ts. Therefore, it is possible to prevent the power supply circuit from being excessively opened and closed.

Furthermore, the above embodiment can be implemented by being modified as described below.

‧ The control unit 30 may also switch to the prohibition mode after the pressing operation of the operation unit is released. At this time, the transition to the prohibition mode can be made coincident with the timing at which the display lamp 25 blinks, and the display lamp 25 can be started to blink when the push operation time Tp reaches the predetermined time Ts, and after the pressing operation of the operation portion is released , converted to disabled mode. Even with the above configuration, it is possible to determine whether or not the operation unit is subjected to the long press operation, and then output a control signal corresponding to the operation state.

‧ It is also possible to use an operation switch that outputs an analog operation signal, and determines whether an operation signal accompanying the pressing operation is output by whether or not the output value of the operation switch is greater than or equal to a predetermined value. Alternatively, an operation switch for outputting a digital operation signal may be employed, and by detecting a switching edge of the OFF signal and the ON signal, it is determined whether or not an operation signal accompanying the pressing operation is output.

(Embodiment 3)

Hereinafter, a switch device 11 according to a third embodiment of the present invention will be described. This embodiment is the same as the basic configuration of the first embodiment, and differs in the operation of the illumination load L and the display lamp 25 by the operation of the operation switch 27. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and their description is omitted.

In the present embodiment, by performing a long press operation on the operation handle 16 of the switch device 11, the control unit 30 can be switched to the disable mode to disable the wireless signal, and the light can be turned on before the long press operation. The light state is reversed. In other words, the lamp that is inadvertently lit by the wireless control can be turned off, and the wireless control can be prohibited until the operation of the operation handle 16 is performed next time. Therefore, the lamp replacement operation can be performed with peace of mind. Further, when the control unit 30 is in the prohibition mode, the display lamp 25 blinks, so that it is easy to visually recognize that the wireless signal is invalid.

Moreover, for example, in the normal mode, although the operator outside the detection area of the human body sensor wants to keep the lighting state of the lamp, the power supply circuit is closed because other people in the detection area are outside the detection area. . At this time, the operator can cause the control unit 30 to switch to the prohibition mode by performing a long press operation on the operation handle 16, thereby making the wireless signal invalid, and inverting the lamp from the lighting state before the long press operation. In other words, the lamp that is inadvertently turned off by the wireless control can be turned on, and the wireless control can be prohibited until the operation of the operation handle 16 is performed next time, so that the operator can perform the work in the original state of the desired lighting state.

Next, an operation sequence of the switching device 11 according to the third embodiment of the present invention will be described with reference to Fig. 7 .

First, a case where the operation load 16 is short-pressed when the illumination load L is in the OFF state and the display lamp 25 is in the ON state in the normal mode will be described.

As shown in FIG. 7(a), when the operation switch 27 is pressed by the operation handle 16 and the operation piece 23 at time t1, the operation switch 27 starts outputting an operation signal. Thereby, the control unit 30 detects the switching edge when the operation signal is started to be output, reverses the opening and closing state of the switching element SW, and switches the display lamp 25 from the ON state to the OFF state. Further, the control unit 30 counts (times) the output time of the operation signal, that is, the pressing operation time Tp, and compares it with the predetermined time Ts at a predetermined interval, thereby determining whether or not the pressing operation time Tp exceeds the predetermined time. Ts.

Then, when the pressing operation of the operation switch 27 is released at the time tr (t1 < tr < t2), the operation switch 27 ends the output of the operation signal. Further, the control unit 30 detects the switching edge at the end of the output of the operation signal, thereby ending the counting of the pressing operation time Tp. Thus, since the pressing operation time Tp at the end of counting is smaller than the predetermined time Ts (Tp<Ts), the control unit 30 determines that the pressing operation of the operating handle 16 is a short pressing operation, and ends the processing. Thereby, the illumination load L in the extinguished state is reversed to the lighting state, and the display lamp 25 in the lighting state is turned off.

On the other hand, when the illumination load L is in the ON state and the display lamp 25 is in the OFF state, the operation handle 16 is short-pressed in the same manner, the illumination load L is turned off, and the display lamp 25 is turned on.

Next, a case will be described in which the operation handle 16 is long-pressed when the illumination load L is in the OFF state and the display lamp 25 is in the ON state in the normal mode.

As shown in FIG. 7(b), when the pressing operation of the operation switch 27 is started via the operation handle 16 and the operation piece 23 at time t1, the operation switch 27 starts outputting an operation signal. Thereby, the control unit 30 detects the switching edge at the start of the output of the operation signal, reverses the opening and closing state of the switching element SW, and switches the display lamp 25 from the ON state to the OFF state. Then, the control unit 30 counts the pressing operation time Tp and compares it with the predetermined time Ts at a predetermined interval, thereby determining whether or not the pressing operation time Tp exceeds the predetermined time Ts.

When the pressing operation time Tp exceeds the predetermined time Ts (Tp ≧ Ts), the control unit 30 determines that the pressing operation of the operating handle 16 is a long-pressing operation, thereby shifting to the prohibition mode, and causing the display lamp 25 to blink. Thereby, the illumination load L in the extinguished state is reversed to the lighting state, and the display lamp 25 is in the blinking state.

Next, a case will be described in which the operation handle 16 is long-pressed when the illumination load L is in the ON state and the display lamp 25 is in the OFF state in the normal mode.

As shown in FIG. 7(c), when the pressing operation of the operation switch 27 is started via the operation handle 16 and the operation piece 23 at time t1, the operation switch 27 starts outputting an operation signal. Thereby, the control unit 30 detects the switching edge at the start of the output of the operation signal, reverses the opening and closing state of the switching element SW, and switches the display lamp 25 from the OFF state to the ON state. Then, the control unit 30 counts the pressing operation time Tp and compares it with the predetermined time Ts at a predetermined interval, thereby determining whether or not the pressing operation time Tp exceeds the predetermined time Ts.

When the pressing operation time Tp exceeds the predetermined time Ts (Tp ≧ Ts), the control unit 30 determines that the pressing operation of the operating handle 16 is a long-pressing operation, thereby shifting to the prohibition mode, and causing the display lamp 25 to blink. Thereby, the illumination load L in the lighting state is reversed to the extinguished state, and the display lamp 25 is in the blinking state.

As described above, in the normal mode, when the control unit 30 detects the switching edge at the start of the operation signal output, that is, when the pressing operation of the operation unit is started, the opening and closing state of the switch is reversed, whereby the short pressing operation is performed. The load control of the lighting load L can be quickly performed in the case of a long-press operation or a long-press operation. Further, since the normal operation mode is switched to the prohibition mode when the pressing operation time Tp exceeds the predetermined time Ts, and in the prohibition mode, the self-prohibition mode is switched to the normal mode at the start of the pressing operation of the operation portion, and thus The operation handle 16 for performing load control of the lighting load L is operated to quickly control the operation mode of the control unit 30.

Here, when the mode switching is prohibited, if the opening and closing state of the switching element SW is to be maintained in the state before the long pressing operation, in order to avoid unnecessary opening and closing control, it is necessary to distinguish whether or not the long pressing operation is performed, and then load control is performed. . Therefore, when the load control with the short press operation is performed, in order to confirm the short press operation, it is necessary to wait until the short press operation is released, and then perform load control. In this regard, in the present embodiment, since the opening and closing state of the switching element SW is reversed during the prohibition mode transition, the load control can be quickly performed without waiting for the release of the short pressing operation.

According to the embodiment described above, the following effects can be obtained.

(1) Since the opening and closing control of the switching element SW and the conversion of the control unit 30 to the prohibition mode can be performed via the shared operation unit, it is not necessary to provide a dedicated operation switch for the conversion of the control unit 30 to the prohibition mode, which is simple. The switch device 11 is constructed. Further, by the long-press operation of the operation handle 16, the operation mode of the control unit 30 is switched from the normal mode to the prohibition mode in which the opening and closing control of the switching element SW is not performed based on the wireless signal, and the opening and closing state of the switching element SW is self-contained. The state before the long press operation is reversed, so that the load control based on the wireless signal can be made invalid, and the desired load state can be set.

(2) In the first mode, the control unit 30 reverses the opening and closing state of the switching element SW at the start of the pressing operation of the operation unit, so that the switching element can be quickly opened and closed. Further, when the pressing operation time Tp exceeds the predetermined time Ts, the normal mode is switched to the prohibition mode, so that it is possible to determine whether or not the operation unit is subjected to the long press operation, and then to the prohibition mode.

Furthermore, the above embodiment can be implemented by being modified as described below.

In the normal mode, the control unit 30 may invert the open/close state of the switching element SW when the switching operation of the operation unit is stopped, that is, when the switching edge at the end of the operation signal output is detected. Thereby, it is possible to invert the open/close state of the switching element SW after determining whether or not the operation unit is subjected to the long press operation.

When the opening and closing state of the switching element SW is reversed at the start of the pressing operation, if the long pressing operation is performed when, for example, the lighting load L is in the ON state, the lighting load L is changed during the long pressing operation. The OFF state causes problems that are difficult for the user to operate. With this configuration, as described above, when the opening and closing state is reversed when the pressing operation is released, the user can arbitrarily adjust the timing at which the opening and closing state is reversed, so that the above problem can be avoided.

‧ The control unit 30 may also switch to the prohibition mode after the long-press operation of the operation unit is released, that is, when the switching edge at the end of the operation signal output is detected. Thereby, it is possible to switch to the prohibition mode after determining whether or not the operation unit is subjected to the long press operation.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
