Float Switch Working Theory:
(1) 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.
(2) Capable of switching up to 250Vac/200Vdc . With a range of cable length and connector options.
(3) Ideally suited to liquid and air conditioning condensate and industrial process control applications.
