Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a collective operation switch device that can perform individual operations corresponding to each load and collective operations.

[Background technology]

BACKGROUND ART Conventionally, there are wiring devices such as a three-way switch, which are placed at a location where a load is located and at a location where centralized control is possible, so that the load can be turned on and off at either location. However, in this type of device, in order to turn on or off multiple loads at the same time, all corresponding switches had to be turned on or off. Therefore, even when performing relatively regular on/off operations, such as before going to bed or when guests come over, it is necessary to operate all the switches in the same way, which increases the number of operations and is cumbersome.

[Purpose of the invention]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a collective operation switch device that does not have the above-mentioned inconveniences.

It is designed to let you know what has happened. That is, 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 indicates on, and if it is "L", it indicates off.
Retains the output until the next operation is detected. and,
The power supply voltage is switched in response to this output. The on/off state discrimination circuit 8 detects whether the load 1 is on or off by discriminating the voltage between the signal lines L, and lights up the on display element LED ₁ or the off display element LED ₂ to indicate the state of the load 1.
