Description

Switching device

The present invention relates to a switch device used as a terminal monitor in a remote monitoring system including a transfer unit having a load controlled by a switch of a terminal monitor and a terminal controller, corresponding to respective addresses The control table is transmitted, and the transmission signal from the terminal monitor is transmitted to the terminal controller corresponding to the control table, whereby the remote control of the load can be performed.

At present, in order to perform remote control of a load, a known technique is to transmit a transmission signal including an on/off information of a switch via a signal line, and to open and close a relay for turning on/off the power of the load by using a transmission signal.

As such a remote control system, a terminal controller having a terminal monitor having a switch and a relay having a power source for turning on/off a load is provided as a terminal device, and a central control system having a transmission unit as a center device is provided. It is also possible to set the terminal monitor and the terminal controller every several times. The transmitting unit, the terminal monitor and the terminal controller are connected to the two-wire signal line, and the transmitting unit separately identifies the terminal monitor and the terminal controller by using terminal addresses separately set in the terminal monitor and the terminal controller.

The transfer unit includes a memory that stores a data table corresponding to the terminal monitor and the terminal controller according to the terminal address, that is, a control table for the on/off information of the switch in any of the terminal monitors. When the multiplex signal is transmitted to the transmitting unit, by controlling The watcher transmits and receives an instruction to open and close the relay to the terminal controller corresponding to the terminal monitor by using the transmission signal, and the relay is turned on and off in the terminal controller that receives the instruction. Since the indication of the opening and closing relay reflects the opening/closing information of the switch, although the transmitting unit is interposed between the terminal monitor and the terminal controller, the transmission signal containing the switch on/off information is transmitted by the signal line, thereby The on/off information of the switch is reflected in the opening and closing of the relay.

However, in general, each of the terminal monitors has a plurality of switches of circuits, and a load of a plurality of circuits is connected to each of the control terminals. In the control table provided in the transfer unit, the switch and the load circuit can be respectively associated. That is, when the terminal monitor has a plurality of switches, only the terminal address unique to the terminal monitor corresponds to all the switches provided to the terminal monitor, so that the only switch that is operated can not be specified in practice. Therefore, in each terminal monitor, each switch is assigned an operation sequence number, and the address of the operation sequence number is added as the address of the switch after the terminal address of the terminal monitor, thereby enabling the specific switch of the specific operation. . Similarly, the load sequence number is assigned to each load in the terminal controller, and the address of the load sequence number is appended to the terminal address of the terminal controller as the load address. Alternatively, a load circuit may be formed by a plurality of loads connected to a terminal controller, in which case the terminal address of each terminal controller is used as the address of the load.

Further, in the control table, in addition to combining the switch and the load one-to-one, it is also possible to combine one-to-many. For example, as long as the power of the lighting fixture as the load is turned on and off by the relay, in the transmission unit It is possible to set individual control of lighting and extinction of a lighting fixture of one circuit by one switch, and overall control of lighting and extinction of a lighting fixture of a plurality of circuits by one switch as a whole. As a whole control, there are group control and pattern control. The group control is to correspond to the range of the load to be controlled, and the operation of one switch is used to open or close the load of the range as a whole, and the pattern control is made into control. The address range of the load of the object and the control state (on or off) of the load corresponding to each address correspond to the closing, and the operation of one switch is used to turn the load of the range on or off respectively.

In the above remote monitoring system, the transmitting unit periodically transmits a transmission signal to the signal line. As the transmission signal, for example, a ±24V bipolar pulse width modulation signal is used. In the terminal monitor and the terminal controller, internal power is ensured by full-wave rectification of the transmission signal. Moreover, power is supplied to the transmission unit using a commercial power source.

Next, the operation of the above-described remote monitoring system will be briefly described.

In the transmission unit, a frequent polling that periodically transmits a transmission signal that cyclically changes the terminal address to the signal line is performed. The bipolar signal is used in the transmission signal, and the bipolar signal includes: a start pulse indicating the start of the signal transmission, a mode data indicating the signal mode, and an address data for respectively identifying the terminal address of the terminal monitor and the terminal controller. The control data (including the operation serial number and the load serial number) for controlling the load, the check and data for detecting the transmission error, and the time gap for receiving the return signal from the terminal monitor and the terminal controller, that is, the signal return period.

In any of the terminal monitors, when a monitor input formed by the operation of the switch is generated, the terminal monitor transmits an interrupt signal synchronized with the start pulse of the transmission signal to the signal line. The terminal monitor that generated the interrupt signal becomes the locked state in which the interrupt flag is set. On the other hand, if the transmitting unit detects the interrupt signal, it transmits a transmission signal using the mode data as the retrieval mode. When the terminal monitor in the locked state receives the transmission signal of the retrieval mode, the terminal address is returned during the signal return period, and the transmission unit receiving the terminal address transmits the transmission requesting the return to the locked state to the terminal monitor of the terminal address. The signal confirms whether it is a terminal monitor that generates an interrupt signal by confirming whether it is in a locked state. When it is confirmed that the terminal monitor has generated the interrupt signal, the transmission signal of the unlocked state is transmitted, and the locked state of the terminal monitor is released.

When the transmitting unit receives the request from the terminal monitor by the above operation, it controls the load of the terminal controller corresponding to the terminal monitor in accordance with the control table. Next, a transmission signal for confirming the operation state of the relay provided in the terminal controller to be controlled is issued, and the operation state of the relay is returned from the terminal controller. After the operation state of the relay received from the terminal controller is confirmed by the transmission unit, if the current operation state of the relay is off, a transmission signal containing the operation state reversed to ON is transmitted to the terminal monitor having the switching operation, and also Send the same content transmission signal to the terminal controller. Further, the reason why the transmission signal of the content of the control terminal controller is transmitted to the terminal monitor is to reflect the indication state of the indicator light for turning on/off the indication provided on the terminal monitor. Receiving the confirmation message that the terminal controller receiving the transmission signal indicating the action state returns .

In the remote control system described above, when a switch of the terminal monitor is operated, in the transmission unit, the address (terminal address + operation signal) of the switch is controlled by the control table, and the connection is set from the transmission unit to the connection. The terminal controller of the load corresponding to the switch transmits a transmission signal indicating the load control. With such an action, the on/off information of the switch can be reflected in the control of the load.

However, the switching device used as the terminal monitor in the above-described remote control system has at least one of the above-mentioned switches and an address memory for storing the address (terminal address + operation number) set by the switch in the casing. The setting of the address stored in the address memory is performed, for example, using a dedicated address setter different from the switching device. In this example, when the address is set for the switching device, the address set by the address setter is transmitted to the switching device by wired or infrared communication or the like, and the address is stored in the address memory.

However, when a specific address setter is used to set an address, since there is no mechanism for confirming the set address in the switching device unit, when the layout of the switching device or the terminal controller changes, it is necessary to utilize The address setter confirms the address set by the switch device, and the address confirmation operation is troublesome. In addition, the address setter is not used except for the address setting. Therefore, it is stored by the administrator of the remote monitoring system. If it is lost during storage, the address setter must be purchased again when the address needs to be changed. This is a burden for managers.

Therefore, the address can be set in order to not use a dedicated address setter. It has been proposed to add a design of an address setting mechanism in the casing of the switching device, which sets the address stored in the address memory (for example, refer to Patent Document 1). As the address setting mechanism, for example, an address setting mechanism having a plurality of dual in-line switches and performing address setting by binary digits by combining on/off states of the respective in-line switches; An address setting mechanism having a rotary switch and utilizing a rotational position of the rotary switch for address setting with a decimal digit.

Patent Document 1: JP-A-2006-94452, JP-A-2007-124159, JP-A-2007-124159, JP-A-2006-032201

However, in the address setting mechanism of the above configuration, when the number of addresses used in the remote monitoring system increases, the number of addresses that can be selected is increased, and the components of the address setting mechanism are doubled. Plug switch, rotary switch) increased. Especially when there are a plurality of switches in one housing, it is difficult to provide a separate address setting mechanism in each switch due to the limitation of the size of the housing. Therefore, an address setting mechanism capable of setting only an interrupt address is often provided in the casing, and is allocated in advance at the time of manufacture so that the relevant operation sequence is not changed. In addition, in the mode in which the DIP switch is used, the address is set by the binary digit. Therefore, compared with the case where the address is set by the decimal digit, there is also a bit for the administrator of the remote control system or the like. The address is difficult to understand, and the resolution of the address is difficult.

On the contrary, consider a seven-segment display in which the two-digit number of the decimal digit is digitally displayed, and a selection switch composed of the up key and the down key to select the address displayed by the display as an address setting mechanism attached to each One On the above switch, the address in the display display selected by the operation of the selection switch is used as the address of each switch. However, in this configuration, since the display and the selection switch are added to each of the switches, the components of the switching device are greatly increased, which is a hindrance to downsizing and cost reduction of the switching device.

Further, in such a switching device, when the operation switch is pressed and the switching switch is pressed due to an erroneous operation, the operation mode is completely switched. In particular, in a switching device in which a size and shape according to a predetermined specification has been formed, there are many control switches and display devices provided, and the above-mentioned erroneous operation is liable to occur when the distance between the control switch and the changeover switch is very close due to size limitation. .

A first object of the present invention is a switching device capable of setting an address without using a dedicated address setter, and in addition, the structure of the address setting mechanism is not made even if the number of selectable addresses is increased. The elements are added so that any address can be set and the structural elements can be made smaller than the existing structure.

A second object of the present invention is to provide a switching device that suppresses an erroneous operation of a changeover switch when a control switch is pressed.

The switch device of the present invention is used as a terminal monitor in a remote monitoring system, the remote monitoring system includes: a terminal monitor having a switch; and a terminal controller transmitting the on/off information including the switch by a signal line Signal, thus, controlled by the on/off of the switch a load unit having a control table for matching a switch of the terminal monitor and a load controlled by the terminal controller according to respective addresses, by transmitting a transmission signal from the terminal monitor to the corresponding table by the control table The terminal controller can perform remote control of the load. The switch device is characterized in that: at least one of the switches is provided in the housing; the address memory is stored by the switch; the address setting mechanism is configured by the address The address stored in the memory, the address setting mechanism includes: a display disposed in front of the casing and displaying the address; a momentary type selection switch operated when the address is selected; and a determination switch operated when determining the address The mode switching switch switches between the normal mode of transmitting the signal and the address setting mode of the setting address by the terminal controller according to the operation of the switch, and sequentially switches between the operation buttons when the selection switch is operated. The displayed address, when the operation determining switch is operated, stores the address that the display is displaying in the address memory, and the above switch is Address setting mode selection switch serves. According to this configuration, the address setting mechanism sequentially switches the address displayed by the display when the selection switch is operated, and stores the address in the display display in the address memory when the determination switch is operated, therefore, the dedicated address is not used. The address setter can set the address. In addition, since the required address is selected from the addresses sequentially displayed by the display, even if the number of selectable addresses is increased, the structural elements of the address setting mechanism are not increased, and arbitrary address setting can be performed. . Thus, even if there are multiple switches in the housing, an arbitrary address can be set for each switch. Further, since the switch also serves as the selection switch, there is an advantage that the components of the switching device can be reduced as compared with the selection switch having a different setting and a different switch.

A switch device according to a second aspect of the present invention, which is a switch device used in a remote control system, comprising: a switch device having one or more control switches respectively set with an inherent address; and a control device connected to one or more loads And connecting to the switch device via the signal line, and controlling the load corresponding to the operated control switch according to the monitoring data received from the switch device via the signal line when the control switch is operated, wherein the switch device is characterized by: a plurality of control switches each formed by a push button switch and held in the housing such that a button receiving pressure from the front is exposed to the front of the housing; and the changeover switch is constituted by a push button switch And holding the button that receives the pressure from the front exposed to the front of the casing; the communication portion is held in the casing and connected to the signal line, and transmits the monitoring data to the control device; the control portion The housing is housed in the housing, and when the operation switch is pressed, the operation mode is switched between the control mode and the setting mode. The control mode generates monitoring data including address information set in the control switch of the pressed operation when pressing any of the control switches, and controls the communication unit to transmit the monitoring data to the control device, wherein the setting mode is in the pressing operation control At the time of switching, the address of the pressed control switch is changed, and a flat-shaped exposed portion is provided on the front surface of the casing, and the exposed portion is located rearward of the front end of the button of any of the control switches, and is surrounded by the front view. Each of the control switch and the changeover switch has a front end of the push switch located at a position rearward of the exposed portion. According to the invention, since the front end of the button of the changeover switch is located further rearward than the front end of the button of the control switch, the front end of the button of the changeover switch and the front end of the button of the control switch are disposed at the same front and rear positions of each other. phase The erroneous operation of the changeover switch when the operation control switch is pressed can be suppressed.

According to the present invention, there is an effect that the address displayed by the display is sequentially switched when the selection switch is operated, and when the switch is determined to be operated, the address in the display display is stored in the address memory, and therefore, The address can be set using a dedicated address setter. In addition, even if the number of selectable address addresses is increased, the structural elements of the address setting mechanism are not increased, and arbitrary address setting can be performed. Thus, even if there are multiple switches in the housing, an arbitrary address can be set for each switch. In addition, since the switch doubles as the selection switch, the structural elements can be made smaller than the existing structure.

According to the present invention, a flat-shaped exposed portion is provided on the front surface of the casing, and the exposed portion is located further rearward than the front end of the button of any one of the control switches, and each control switch and the changeover switch are respectively surrounded and viewed from the front. The front end of the button of the switch is located further rearward than the exposed portion. Therefore, since the front end of the button of the switch is located further rearward than the front end of the button of the control switch, the front end of the button of the switch and the control switch The erroneous operation of the changeover switch when the operation control switch is pressed can be suppressed as compared with the case where the front end of the button is disposed at the same front and rear position.

[First Embodiment]

The switch device 1 described in the present embodiment is a switch device used in a peripheral terminal display in the remote monitoring system shown in Fig. 2 . The basic structure of the remote monitoring system and the remote monitoring system described in the column of the prior art The same is true, but in Fig. 2, among the components of the remote monitoring system described in the column of the prior art, the main function 21 as a function of the transmitting unit and the function as the terminal controller are integrated.

The master device 21 includes a main unit 22 that detachably connects the relay Ry that turns on and off the relay Ry of the power sources of the loads L1 to L8. Further, since the master device 21 has a function of a transfer unit, it is connected to the switch device 1 as a terminal monitor by using a two-wire type signal line (not shown), and is provided in the switch 2 of the switch device 1 (refer to The operation of Fig. 1) can be reflected by the on and off of the relay Ry. In addition, the number of circuits of the relay Ry that can be mounted on the main unit 22 of the main device 21 is limited (up to eight circuits here), and in the case where more load circuits are used as the control target, the signal line is used as the terminal. A sub-device (not shown) of the controller is connected to the main device 21, as long as the operation of the switch 2 provided in the switching device 1 is reflected by the ON/OFF of the relay Ry of the sub-device. In addition, the master device 21 can control the relay Ry by internal processing, and therefore, the transmission signal from the transmitting unit to the terminal controller is transmitted without passing through the signal line. However, even in the case of not passing through the signal line, in order to be equivalently processed with the sub-device, information corresponding to the address of the terminal controller is required, and therefore, each relay Ry provided in the sub-device 21 corresponds to the switch 2 by using the control table. .

Here, the master device 21 can connect up to 10 sub-devices, and each of the sub-devices is provided with a relay Ry of up to four circuits. In short, a relay Ry of up to 48 circuits is connected to the remote monitoring system using the switching device 1 of the following embodiment. So, the assumption is that A switch of 1 to 48 serial addresses is assigned to the electric appliance Ry, and 1 to 48 serial addresses are also assigned to the switch 2 of the switching device 1, whereby the relays Ry and 2 of the same serial number correspond in the control table. Further, in the switch 2, in addition to the numbers 1 to 48, a one-off disconnection pattern control for turning off all the relays Ry in the remote monitoring system together, and one of them to be turned on at the same time may be assigned. And turn on the address of the pattern control. That is, if the pressing operation is assigned the switch 2 for the address that is turned off, all the relays Ry in the remote monitoring system are turned off.

As shown in FIG. 1, the switch device 1 of the present embodiment includes a plurality of (here, three) switches 2 in one housing 3. The casing 3 is formed in a rectangular parallelepiped shape, and a pair of attachment pieces 4 are protruded from the upper and lower end faces of the first drawing. The two attachment pieces 4 are connected between the left and right end portions of the first drawing to form a frame 5 having a rectangular frame shape. Hereinafter, the up, down, left, and right of Fig. 1 will be described as up, down, left, and right.

The frame 5 has the same function as the mounting frame used when the wiring device having the embedded shape is attached to a construction surface (not shown) such as a wall surface, and the switch device 1 is constructed by embedding the rear portion of the casing 3 on the construction surface. In the form of a hole (not shown), the back surface of the mounting piece 4 is abutted and fixed to the construction surface around the construction hole. A long hole 6 is inserted through the mounting piece 4, and the long hole 6 is inserted through a bolt (not shown) for attaching the switch device 1 to a buried case that is embedded in the construction surface. A jig hole 7 for sandwiching a structural material (not shown) such as a wall plate constituting the construction surface between the mounting piece 4 and the mounting piece 4 is provided through the both sides of the long hole 6 . A part of the jig (not shown) is locked. At this time, the casing 3 is formed to be juxtaposed with three in the width direction. The size of the wiring device per unit size (three module sizes) is approximately the same size, and the wiring device of the unit size can be mounted on a series of mounting frames that are standardized for the embedded wiring device, and The front side is exposed on the construction surface.

A portion surrounded by the frame 5 in the front surface of the switch device 1 constitutes a functional surface 9, and an operation member 8 that is pressed when the switch 2 is operated is disposed on the functional surface 9. The operating members 8 of the switch 2 are arranged in the up and down direction. In addition to the operation member 8 of the switch 2, the function surface 9 is provided with an indicator lamp 11 for instructing the state of the relay Ry corresponding to each switch 2, a display 12 for use in address setting described later, and a mode changeover switch. 13. The indicator lamp 11 is lit red, for example, in a state where the relay Ry is turned on (that is, a state in which the load is energized), and is turned on in a state where the relay Ry is off (that is, a state in which the load is not energized). .

Further, the switch device 1 includes a switch handle 14 that is attached to the casing 3 so as to cover the functional surface 9. Fig. 1 shows a state in which the switch handle 14 is detached from the casing 3. The switch handle 14 has an operation panel 15 that is equally divided in the vertical direction (here, three equal parts) corresponding to the operation member 8 of each switch 2, and a connection in which the left end portions of the operation panels 15 are connected in the vertical direction. The sheet 16 is attached to the casing 3 by engaging an engaging claw (not shown) provided on the back surface with the casing. Each of the operation panels 15 is supported by the connecting piece 16 so as to be press-fitted rearward (the side of the casing 3), and is protruded from the back side when the switch handle 14 is press-fitted in the state in which the switch handle 14 is attached to the casing 3. The operation member 8 of the corresponding switch 2 is pressed and pressed on the abutment table (not shown). The switch handle 14 is used to control the passage of the load L1~L8 At all times, the switch device 1 is mounted on the casing 3 to increase the operation surface of the switch 2, achieving excellent operability. A display window 17 is provided at a position corresponding to each of the indicator lamps 11 on the connecting piece 16, and the indicator light 11 can be recognized from the front through the display window 17 even in a state where the switch handle 14 is attached. Further, a decorative panel 18 is attached to the front surface of the casing 3 around the switch handle 14 (see Fig. 2).

However, the casing 3 of the switch device 1 of the present embodiment includes an address memory (not shown) that stores the address used by the switch 2 when used as a terminal monitor in the remote monitoring system; An address setting mechanism 19 that sets an address stored in the address memory.

On the functional surface 9 of the casing 3 of the address setting mechanism 19, there is a display 12 for displaying an address, a mode switching switch 13 for switching an operation mode of the switching device 1, a selection switch for selecting an address, and a determination bit. The determination switch for the operation at the address. At this time, the switch 2 also serves as a selection switch, and the mode switching switch 13 also serves as a determination switch. The display 12 corresponds to each switch 2, respectively, but only one determination switch (mode switching switch 13) is provided in the casing 3.

The selection switch (switch 2) and the determination switch (mode changeover switch 13) are each composed of a momentary type push button switch that is turned on when the pressing operation is performed. The mode changeover switch 13 switches between the normal mode in which the transmission signal is transmitted to the terminal controller in accordance with the operation of the switch 2 and the address setting mode in which the address is set in accordance with the operation of the switch 2. The mode changeover switch 13 is provided at a position covered by the switch handle 14 in a state where the switch handle 14 is attached to the casing 3. Thus, the switching device 1 is used for the load L1 In the normal case of the control of ~L8, the mode changeover switch 13 is incapable of being operated by being covered by the switch handle 14, and the case where the mode changeover switch 13 is operated to shift to the address setting mode is prevented. In other words, the operation mode can be shifted to the address setting mode only in a state where the switch handle 14 is detached from the casing 3, and the switching device 1 is in the normal mode in a state where the switch handle 14 is mounted to the casing 3. Under the action.

As an example of the display 12, a two-row, seven-segment liquid crystal display is employed. Further, on the functional surface 9 of the casing 3, a correspondence display portion 20 indicating the correspondence relationship between the display 12 and the switch 2 is provided around each display 12. The correspondence display portion 20 is depicted as surrounding each display 12 by a broken line, and partially indicates the corresponding switch 2. In addition, in the address setting mode, the indicator light 11 is set to a lighting state different from the normal mode (here, red flashing and blinking), whereby the operation mode can be displayed by the indicator light 11.

The address setting mechanism 19 configured as described above, in the address setting mode, when the selection switch (switch 2) is pressed, sequentially switches the address displayed by the display 12, and determines that the switch (mode switching switch 13) is operated, The address displayed by display 12 is stored in the address memory. Here, as the address in each switch 2 of the switching device 1 is assigned addresses 1 to 48, when the switch 2 is operated in the address setting mode, the display 12 sequentially displays the digits 1, 2, 3, ..., 48. Further, in the present embodiment, in addition to No. 1 to No. 48, it is also possible to assign a collective disconnection pattern control for turning off all the relays Ry in the remote monitoring system together, and to collectively turn them on. The address of the pattern control is also turned on, and therefore, by pressing the switch 2 of the operation address setting mode, the address that is also disconnected can also be selected. That is, "off (OF)", the address that is turned on at the same time is "ON".

Specifically, when the display 12 displays "48" in the address setting mode, if the switch 2 is operated once, the address 12 that is turned on is displayed as "on" in the display 12. Further, if the operation switch 2 is pressed, the address "OFF" which is always disconnected is displayed on the display 12. In addition, when "OF" is displayed on the display 12 in the address setting mode, if the switch 2 is operated once, the display 12 displays "--" which cannot be set (ie, not set), if When the switch 2 is operated, the display of the display 12 is restored to "1".

Here, the address setting switch 19 has a fast forward function, in the address setting mode, when the selection switch (switch 2) is continuously pressed for a predetermined period of time (ie, long press), The addresses displayed on the display 12 are sequentially switched in a fast forward manner. When the switch 2 is pressed for more than the long press time, if the pressing operation of the switch 2 continues, the fast forward of the address continues. Therefore, according to the present embodiment, when the address of the second half is set in the case where the number of selectable addresses is large, the time required until the display address of the display 12 is displayed can be shortened by the fast forward function, and the result is The efficiency of the site setting is improved. Further, by the long press of the switch 2 in the address setting mode, the operation for utilizing the fast forward function can be performed, and therefore, the switching device can be reduced as compared with the case where the special switch is additionally provided in order to obtain the fast forward function. The structural elements of 1. Further, in the present embodiment, as an example, the long press time is set to 3 seconds.

Moreover, if the display 12 displays the required address (or displays an unset "--"), if the mode switch 13 is pressed In the press operation, the address in the display of the display 12 is stored as the address of the switch 2 in the address memory corresponding to the display 12, and the operation mode is switched to the normal mode. In the normal mode, since the switch 2 does not function as a selection switch, even if the address of the switch 2 is operated, it will not be changed. In the present embodiment, in the normal mode, the display 12 corresponding to each switch 2 displays the address of each switch 2, but the display 12 can also display the address only in the address setting mode. In addition, Fig. 1 shows a state in which the address is not set for any of the switches 2 (the display of the display 12 is "--").

Further, the address setting unit 19 has a mode reset function which is in the address setting mode, and when the switch 2 continues to be unoperated for a predetermined period of no operation, even if the mode change switch 13 is not operated, The action mode is also automatically switched to the normal mode. Thereby, for example, in the address setting operation, even if the operator leaves the scene due to an emergency and the switch device 1 is placed in the address setting mode as it is, the normal mode is automatically restored in the no-operation time, and therefore, the normal mode can be reduced. A person other than the small operator does not know that it is operating the switching device 1 in the address setting mode, thereby causing the possibility that the address is erroneously changed. Here, in the case where the mode reset function is restored to the normal mode, since it is determined that the switch mode changeover switch 13 is not operated, the address in the middle of the setting displayed by the display 12 is not stored in the address memory, and thus The address of switch 2 is not incorrectly updated to the address set midway. Therefore, even when the switching device 1 is in the address setting mode, even if the address of the display 12 is switched by operating the switch 2 for the purpose of controlling the loads L1 to L8, Avoid this address being incorrectly set in the address memory. In addition, when the mode reset function is restored to the normal mode, the address in the address memory is not updated. Therefore, the address before the operation mode is switched to the address setting mode is continuously applied, and the display 12 also displays the address.

Next, a method of setting the address of each switch 2 in the switching device 1 of the present embodiment will be described with reference to FIG.
