Description

[Detailed Description of the Invention] [Technical Field] The present invention provides individual operations corresponding to each load,
This invention relates to a batch operation switch device that can perform batch operations.

[Background Art] Some conventional wiring devices, such as 3-way switches, are arranged so that the load is located at the location where the load is located and the location where the load is centrally controlled, so that the load can be turned on and off at either location. . In order to turn on or off multiple loads, it was necessary to turn on or off all the corresponding switches. Therefore, even relatively regular on/off operations, such as before going to bed or when guests arrive, require a large number of operations and are cumbersome.

[Object of the Invention] The present invention is a collective operation switch device made in view of the above-mentioned problems. To provide a collective operation switch device equipped with a decorative cover that is hidden from view from the outside and can be easily operated by simply removing it when setting.

[Disclosure of the Invention] FIG. 4 shows a block diagram of a circuit used in the collective operation switch device of the present invention. In the figure, load 1 ₁ ... is the parent device 2 ₁ provided correspondingly.
It is connected with the AC power source AC to ..., and the master unit 2 ₁ ...
... is connected to the collective operation switch section A. The master device 2 ₁ ... has a configuration as shown in FIG.
Load 1 is controlled by turning off. The load control section 3 is driven by an on or off signal from an on/off signal processing circuit 4, and this on/off signal processing circuit 4 is driven by an on/off signal discrimination processing circuit 5.
Creates an on or off signal based on the output of the output. The on/off signal discrimination processing circuit 5 discriminates the operation signal from the slave device 9 (described later) of the collective operation switch A connected to the connection terminal, and generates an on/off discrimination output to the on/off signal processing circuit 4. At the same time, the slave power supply switching circuit 6 is controlled to switch the power supply voltage applied between the connection terminals according to on and off states. The power supply voltage is obtained from the power output from the power supply section 7, and is supplied to the child device 9 side. The slave unit 9 has a basic circuit configuration as shown in Fig. 6, in which an individual operation switch SW is connected in parallel between the power input terminals ₀ and ₁ , and the voltage between the power input terminals ₀ and ₁ is controlled by a valve. Separately, the state of load 1 on the main unit 2 side is determined.
The off-state discrimination circuit 8 is connected, and the individual operation switch SW is turned on to short-circuit the signal line L connected to the main unit 2, and the signal is individually transmitted to the on/off signal discrimination processing circuit 5 on the main unit 2 side. It is designed to notify that the operation switch SW has been operated. In other words, on
The off-signal discrimination processing circuit 5 detects the current flowing due to the short circuit, detects the operation, and inverts the discrimination output from the previous state. Here, for example, if the discrimination output is "H", it indicates on, and if it is "L", it indicates off, and the output is held until the next operation is detected. The power supply voltage is then switched in response to this output. The on/off state discrimination circuit 8 discriminates the voltage between the signal lines L, detects whether the load 1 is on or off, and displays the on display element LED ₁ or the off display element
Light up LED ₂ to display the status of load 1.

By the way, the collective operation switch part A used in the present invention
Then, corresponding to the 6 master units 2 ₁ ..., the 6 slave units 9 ₁
Each sub-device 9 ₁ ... has a full-wave rectifier 10 ₁ ... connected in parallel to the individual operation switch SW ₁ ..., and _the above-mentioned Along with the function of the on/off state discrimination circuit 8,
It is constructed by connecting an on/off control section 11 ₁ . . . having a switching function to turn on and off the output end of the full-wave rectifier 10 ₁ . . . in response to an external control signal. The above-mentioned external control signal is generated by the logic control circuit 12, and this logic control circuit 12 is an on/off control section of the corresponding slave device ₉₁ ... according to the operation of the collective operation switches SWa, SWb, SWc. 11 ₁
. . . It is designed to send an external control signal to turn on or off. Here, the individual loads 1 ₁ ..., that is, slave devices 9 ₁ ... and the collective operation switch SWa,
The combination relationship between SWb and SWb can be arbitrarily set by the load control selection section 13. That is, the load control selection unit 13 selects the individual loads 1 ₁ .
SWb and the relationship between SWb and the operating mode can be set. The constant voltage power supply unit 14 receives the outputs from the full wave rectifiers 10 ₁ . . . through the diodes d, respectively, and obtains a constant voltage power supply.

Therefore, when performing individual operations, all you have to do is operate the individual operation switch SW ₁ ... provided on the slave device 9 ₁ ... corresponding to the load 1 ₁ ... that you want to operate. is a batch operation switch
Just operate SWa, SWb, and SWc. In the case of this batch operation, the logic control circuit 12 controls each load ₁ ...
The state of... is detected by the input from the on/off control section 11 ₁ ..., and based on that state and the selected state of the load control selection section 13, the child device _{9 1} ... corresponding to the predetermined load 1 1 ... An external control signal is applied to the on/off control section 11 ₁ ... of the full-wave rectifier 10 ₁ ... to short-circuit the output distance of the full-wave rectifier 10 1 ... by switching the individual operation switch.
Similarly to SW _{1 .} . ., a short circuit current is caused to flow through the parent device 2 _{1 .} . . to turn on or off the corresponding load 1 ₁ .

In the above circuit example, the power supply unit 7 of the parent device 2 is a three-wire system in which the AC power supply AC is directly connected.
As shown in the figure, a two-wire system in which an alternating current power source AC is connected via a load 1 may be used.
