Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to the structure of a wireless switch for controlling loads such as lighting equipment.

[Conventional technology]

In order to be able to wirelessly remotely control a load such as a lighting fixture that is controlled by a built-in switch mounted on a wall, it is necessary to use a wireless switch itself, as shown in Japanese Patent Application Laid-open No. 57-72639. The built-in switch is placed at the connection point with the power line of the lighting equipment, and the embedded switch is always on and the transmitter opens and closes the wireless switch body to control the lighting and extinguishment of the lighting equipment.

[Problem to be solved by the invention]

In this case, the embedded switch and the wireless switch body are located in separate locations, which increases the effort required to install both. Therefore, the two are inevitably connected in series, and for this reason, if the embedded switch side is turned off, the lighting equipment cannot be controlled by the wireless switch itself. Of course, both switches are 3
This situation can be prevented by configuring it with a road switch, but it cannot be used where existing two-wire wiring is installed. The present invention has been made in view of these points, and its purpose is to provide a structure of a wireless switch that can be operated both remotely and manually by incorporating an operation switch for manual operation. be.
