A plurality of switch control units for controlling a water level adjusting device connected to the drain pump

摘要

In the present invention, one switch control unit selectively turns on and off a switch unit of the water level adjusting device, and a drain pump connected to the water level control device is selectively operated to control the water level adjusting device provided in the water tank, If one of the water level control devices installed in the water level control unit fails to operate the drain water pump so that the water can be easily discharged to the water level control unit by operating one drainage pump, The drainage pump is operated to discharge the water from the water tank. One water level control device and one drainage pump are installed in the existing water tank, and damage caused by failing to discharge water from the water tank due to failure of the water level control device or drain pump A plurality of water pumps are installed in a water tank to be prevented from the original, It relates to a switch control unit for controlling the associated level control apparatus.
