Conventionally, a plurality of operation switches used in this type of system are collectively arranged to provide a remote control system switch device. The conventional remote control system switch device has a plurality of remote control operation switches. They are collectively installed in an appropriate space (for example, an embedded wiring box), and a signal line 63 for time division multiplex transmission is connected to each monitoring terminal 61 for monitoring the operation of these operation switches.
In some cases, one switch device controls a plurality of lighting fixtures in a block.

[0006]

However, in the above-described conventional example, since the operation switches are simply arranged in a row, the correspondence between the blocked load and the operation switches is determined. Is difficult to understand, and when the division of the control blocks of the loads (lighting equipment) L ₁ ... Becomes complicated, the problem becomes more difficult to understand.

[0007] Therefore, a section area map or the like representing the section of the control block is pasted near the remote control switch device,
There has been a method of associating the relationship between the segmented area map and the operation switch with a number, a color, or the like. However, this method also has a problem that it is difficult to make a design match with the inner wall surface of the building, and that the aesthetic appearance of the room is impaired.
In addition, when the layout of the load is changed, the method of pasting the sectional area map becomes a problem, and the change of the display corresponding to the operation switches and the method of pasting the sectional area map also become problems.

Therefore, it has been proposed that a plurality of switch insertion holes are formed in the frame unit in a matrix form,
A switch unit or a blank chip formed substantially in the same shape as the front part of the switch unit is inserted into an arbitrary switch insertion hole from the front opening, and a map of a divided area is formed by using the switch unit and the blank chip. This is a switch device for a remote control system that associates a switch unit in a sectional area map with a control block.

However, when a switch unit or a blank chip is inserted into a switch insertion hole formed in a matrix on a frame unit, a gap between adjacent switch units or a blank chip is small, and the switch unit or the blank chip and the switch are inserted. It was difficult to release the locked state with the insertion hole, and the removal operation was troublesome.
The present invention has been made in view of the above points, and an object of the present invention is to provide a switch unit and a switch unit remover which can easily remove a blank chip from a switch insertion hole.

[0010]

In order to achieve the above object, the present invention provides a plurality of switch insertion holes formed in a matrix in a frame unit. Used for a switch device for a remote control system for inserting a blank chip formed in substantially the same shape as the front part of the unit or switch unit, and the portion of the switch unit or blank chip protruding from the rear opening of the switch insertion hole And an elastic locking means which is formed on the side surface of the switch unit or the blank chip so as to be able to protrude and retract so as to protrude outward from the side surface and locks the rear opening edge of the switch insertion hole with the switch unit or the blank chip. Push the switch unit or blank chip forward with the body to be pushed into the side. And a biasing means for issuing.

[0011]
