1. Working Principle
Fix magnetic reed switch to a closed and nonmagnetic conduit. When the float switch is empty inside and fastened with permanent ring magnet approaches the switch along with the conduit under the buoyancy of liquid, the contact would be ON under the function of magnetic force, otherwise, when the float aparts away from the magnetic reed switch, the contact would be OFF. Thus signals of ON or OFF would be output and used for alarming or remote control.
