The Working Theory of Level Switch:
When the float ball rises or falls with the liquid to the level of the switch, The magnetic force of magnet which inside of the float ball will cause the reed switch to turn ON. When the float ball move away from the reed switch, the reed switch will turn OFF. Normally open, normally closed or change over type for choosing.
