Abstract

A switch control system for controlling an electrically conductive fluid supply to a tank, includes a detection circuit, a gate circuit, a control circuit and a switch circuit. The detection circuit detects a fluid level in the tank and outputs a voltage level signal. The gate circuit receives the voltage level signal and outputs control signals accordingly. The control circuit receives the control signals and outputs a first voltage and a second voltage accordingly. The switch circuit receives the first voltage and the second voltage and turns on and turns off the electrically conductive fluid supply to the tank in accordance with the first voltage and the second voltage.
