Description

  The present invention relates to an operation switch wiring device used in, for example, a remote monitoring control system that performs remote monitoring control of a load.

  Conventionally, as disclosed in Patent Document 1, this type of remote monitoring and control system includes a two-wire signal line, a transmission unit, an operation terminal that monitors the state of an operation switch, and a relay contact. A control terminal for turning on / off the power of the load and an address setting unit for setting an address of the control terminal controlled by collective control such as group control or pattern control are provided. In the conventional remote monitoring control system, the transmission unit recognizes the operation terminal and the control terminal individually using the individual addresses set in the operation terminal and the control terminal.

  However, in the conventional remote monitoring and control system described above, the number of system components other than the operation terminal and the control terminal increases, and the address setting unit is used only when setting an address, so that unnecessary system components increase during normal control. There was a problem that.

In order to solve the above problem, a remote monitoring and control system including an operation switch wiring device is provided in place of the operation terminal and the address setting device. Fig.8 (a) is a front view of the cover 90 in the conventional operation switch wiring instrument. FIG. 8B is a side view of the cover 90 and the circuit board 7 in the conventional operation switch wiring device. As shown in FIG. 8A, the conventional operation switch wiring device includes eight operation buttons 91... On the cover 90. As shown in FIG. 8B, each operation button 91 includes a drive unit 92 that pushes and drives the push button 700 of the push button switch 70, and a push operation unit 93 that is positioned directly above the drive unit 92. When the push operation unit 93 is pushed, the pushed force is applied to the push button 700 of the push button switch 70 via the drive unit 92.

The added transmission signal is returned to the base unit 1. If the address included in the received transmission signal matches the address of the relay block 11 of the parent device 1, the master unit 1 controls the opening / closing of the relay block 11 with the matching address. A control signal is transmitted to each slave unit 2, and each slave unit 2 controls the opening and closing of the relay block 21 of the corresponding address. Thereafter, the control state of the corresponding relay blocks 11 and 21 is returned from the master unit 1 to the operation switch wiring device 4, and the light emitting diode 72 (see FIG. 1) corresponding to the pushed pushbutton switch 70 is turned on or off. Thus, the open / close state of the relay blocks 11 and 21 (that is, the on / off state of the load 3) is displayed.

  As described above, according to the present embodiment, as shown in FIG. 3B, the push operation portion 832 of the operation button 83 can be provided in a deviated position with respect to the drive portion 831. Therefore, the push button switch 70 (FIG. 1), the position of the push operation portion 832 of the operation button 83 can be freely designed according to the application and design. Further, since sink marks, blurring, and deformation of the operation button 83 can be reduced, stable manufacture can be achieved. Furthermore, since the terminal parts 65 and 65 of the body 6 and the circuit board 7 are connected by the metal fitting 66, it can be assembled easily and disconnection can be reduced.
