Description

The present invention relates to a switch box, and more particularly to a switch box structure having an excellent drainage function.

The opening and closing operation of the electric shutter for opening and closing the building opening is usually performed using a push button switch in a switch box embedded in the wall surface. The pushbutton switch in the switch box is connected to the open / close switch in the shutter case by wiring drawn out into the switch box through the pipe, but when the slat is wound, the water adhering to the slat accumulates in the shutter case. , May enter the switch box through the piping. In addition, moisture generated in the switch box may become water droplets, or rain water may blow in from the front of the switch box when the lid of the switch box is opened.

If water enters the switch box, the water will accumulate inside and corrode inside. If water accumulates in the switch box, it may cause a short circuit of the connection portion of the wiring, and if corroded water flows out to the wall surface, the wall may be soiled.

Patent Document 1 discloses a waterproof structure of a switch in which the switch is covered with a waterproof cover. However, it is necessary to prepare a waterproof cover separately and to cover the switch with this. In addition, if the switch itself has a waterproof function, the problem caused by the corrosion of water accumulated in the switch box cannot be solved.
