1. Working Principle
When the float goes up and down along the fixed support or shaft under the liquid buoyancy and swings up and down, the permanent magnet at the end of float fixed shaft swings accordingly under lever function, which consequently drives the micro swich in the junction box to move and output the ON or OFF signal for alarming or remote control.
