DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a switch unit used in a remote control switch device or the like.

[Prior Art] As a system for remotely controlling loads such as lighting fixtures placed in various parts of a building, a central control device 1 is used as shown in FIG.
, the unique address is set, and the operation switch S1...
There is a time division multiplex transmission system in which a monitoring terminal device 2 for monitoring the load L1 and a control terminal device 3 for controlling the load L1 are connected to a signal line 4.

As shown in FIG. 8, this system controls a start pulse signal ST, a mode data signal MD indicating the signal mode, an address data signal AD for calling the terminal 2.3, a load L1, etc. from the central control unit M1. Control data signal C
D. A time division multiplex transmission signal consisting of a checksum data signal C8 and a return signal period WT that sets the signal return period from the terminal device 2.3 is transmitted, and each terminal device 2.3 has a signal line When the data of the address data signal AD of the transmission signal received via 4 matches the own unique address, the control data of the control data signal CD is taken in, and the monitoring data signal ( The operation state monitoring data of the operation switch s1..., the operation state monitoring data of negative*L,...) are returned. Under normal conditions, the central control device 1 sends out a dummy transmission signal in which the mode data signal MD is in a dummy mode, and in response to the operation of the operation switches S, . . . When the interrupt signal is returned in synchronization with the transmission period of the signal SP, the interrupt generating terminal 2 is detected, the terminal 2 is accessed, and the operating state monitoring data of the operating switch s1... is returned, Control data to be transmitted to the control terminal device 3 that controls the load L1... corresponding to this operating state monitoring data is created, and the control data signal CD is transmitted as the transmission signal shown in FIG. 8 via the signal line 4. The load L1... is controlled by time-division multiplex transmission to the control terminal device 3, and the monitoring terminal device 2 is controlled based on the operating state monitoring information of the load L1... sent back from the control terminal device 3. Control data for controlling blinking of an operation display element (not shown) is transmitted.

By the way, conventionally, a remote control switch device is a device in which a plurality of operation switches S, to S4 used in this type of system are collectively arranged, and the conventional remote control switch device X is a remote control switch device as shown in FIG. Operation switch 81 for control
~S, and install them in a suitable space (for example, an embedded wiring box), and connect these operation switches S.
A signal line 4 for time-division multiplex transmission is wired to a monitoring terminal 2 that monitors the operations of , ~S, and a plurality of lighting fixtures can be block-controlled with one operation switch 81-S4. There was something I did.

In the illustrated example, the operation switches S to S4 are integrated into the monitoring terminal 2 to form a switch monitoring terminal. However, in the conventional example described above, the operation switches 81 to S
, are simply arranged in a row, it is difficult to understand the correspondence between the blocked loads and the operation switches S, ~S, and the load (lighting equipment) Ll When the classification of control blocks becomes 5III, there is a problem that it becomes increasingly difficult to understand.

Therefore, there was a method of pasting a divided area map M etc. representing the division of the control block near the remote control switch device X and associating the relationship between the divided area map M and the operation switches 81 to S by numbers, colors, etc. .

However, with the conventional method of pasting the divided area map M that associates the operation switches S, ~s4 and the load with the load near the remote control switch device X, it is difficult to match the design with the inner wall surface of the building. There was a problem that the aesthetic appearance of the room was spoiled. In response to changes in the layout of the load, the method of pasting the divided area map M is a problem, and the method of changing the correspondence display with the operation switches S, ~S and pasting the divided area map M is also a problem. became.

Therefore, as shown in FIGS. 10 to 12, the present inventor developed an operation display element LA consisting of an operation switch S for controlling the load and a two-color light emitting diode that is driven to emit light of different colors in response to on/off of the load. is provided on the front side, and a plurality of switch units 6 from which signal line connection lead wires 5 are led out on the rear side, are made of sheet metal and are bent into a substantially U-shape,

A panel frame 11 made of synthetic resin is attached to the surface, and a panel frame 11 is fitted onto the front side of the panel frame 11 so as to cover the center opening 11a of the panel frame 11, and is covered with the front side of the mounting frame 8 through the center opening 11. A locking protrusion 13 provided on the rear surface of the panel frame 11 is inserted into a locking hole 14 which is used to hold down the layout sheet 12 and the surrounding area of the layout sheet 12. A panel 15 that can be freely locked and attached, a blank chip 16 whose head shape is approximately the same as that of the switch unit 6, and an inner surface of one side piece of the mounting frame 8. The switch unit 6 is removably inserted into the switch insertion hole 7 at a predetermined position according to the layout of the load controlled by the control terminal 3. We are proposing a remote control switch device.

As shown in FIG. 11, the mounting frame 8 includes a mounting hole 17 for mounting on a switch box, and a locking hole 1 for a clip used when installing the mounting frame in the hole drilled in the wall panel.
Corresponding to these holes 17 and 18, convex holes 19 are bored in the fragment 11b of the panel frame 11 so that it can be attached from the panel frame 11 side, as shown in FIG. It is set up.

The layout sheet 12 is made of an elastic synthetic resin sheet with a divided area map drawn inside the frame part 12a, and the position and operation of the operation switch S of the switch unit 6 is displayed by the transparent part 20 in each division. The light from the element LA can be visually recognized, and the operation switch S can be operated via the layout sheet 12. The switch unit 6 has a switch body 6a formed with an external dimension that allows it to be inserted into the switch insertion hole 7 of the mounting frame 8. A circuit as a control terminal is disposed inside the switch body 6a, and an operation switch S and an operation display element are disposed inside the switch body 6a. L
A is disposed near the opening, and a switch cover 6b is attached to this opening.

The front plate of the switch cover 6b has a window hole corresponding to the push button 23 of the operation switch S and an exposure window for the operation display element LA, and when inserted into the switch insertion hole 7, the switch unit 6 is opened. The locking protrusion (not shown) formed on the side surface and the rear peripheral part of the front plate 25 sandwich the mounting frame 8 around the opening of the switch insertion hole 7, so that the switch unit 6 can be inserted and removed freely. It can be inserted into the hole 7.

The blank chip 16 has a front external shape that is a switch unit 6.
It is formed to have approximately the same shape as the switch cover 6b that constitutes the head of the switch cover 6b, and has a locking protrusion (not shown) formed on the side surface of the rear cylinder part.
By holding the mounting frame 8 around the opening of the switch insertion hole 7 between the two, the switch can be detachably inserted into the switch insertion hole 7.

As described above, in the devices shown in FIGS. 10 to 12, the operation switch S can be arranged by simply inserting it into the switch insertion hole 7 of the mounting frame 8 in accordance with the layout of the load. The correspondence relationship between the two routes can be easily recognized on the divided area map of the layout sheet, and control operations can be performed easily. In addition, unlike the conventional example, there is no need to paste the divided area map on the wall, etc., so the aesthetics of the room will not be spoiled. This can be easily handled by inserting and replacing the layout sheet 12.
