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] Conventional wiring devices, such as 3-way switches, are located at the load point and at the central control point, so that the load can be turned on and off at either point. be.
However, in order to turn on or off multiple loads, it is 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 has been made in view of the above-mentioned problems, and its purpose is not only to operate each load individually but also to turn on one or more predetermined loads at once. To provide a collective operation switch device which can be turned off or turned off and eliminates the complexity of operation.

[Disclosure of invention] The present invention will be explained below with reference to Examples.

FIG. 1 shows an overall circuit diagram of the present invention. In the figure, the loads 1 ₁ ... are connected together with an AC power source AC to the corresponding master devices 2 ₁ ..., and the master devices 2 ₁ ... are connected to the collective operation switch section A. The master unit 2 ₁ ... has a configuration as shown in Fig. 2. In Fig. 2, the load 1 is connected to the AC power source AC via the load control unit 3, and the load is controlled by turning on and off the load control unit 3. Control 1. 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 turned on or off by a discrimination output from an on/off signal discrimination processing circuit 5. Create a signal. The on/off signal discrimination processing circuit 5 discriminates the operation signal from the slave device 9 (described later) of the collective operation switch section A connected to the connection terminal, and outputs 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 depending on whether it is on or off. The power supply voltage is obtained from the power output from the power supply section 7,
It is supplied to the child device 9 side. The slave unit 9 has a basic circuit configuration as shown in Fig. 3, and has an individual operation switch between the power input terminals _I0 and _I1 .

Short-circuit between
It is designed to notify you that the SW has been operated. In other words, the on/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 is turned on, and "L"
If so, each 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 lights up the on display element LED ₁ or the off display element LED ₂ to display the state of the load 1. let
