Operating principle

Two permanent magnets which react on each other are separately fixed at the end of the float arm and inside terminal box. 
The float and the arm move up and down with liquid level. 
The float movement by liquid level is transmitted through two magnets to the micro switch Which is linked with a magnet inside the terminal box. And the micro switch sends ON-OFF alarm signals.
