HIGH-SENSITIVITY REED SWITCH: The contacts inside of this water level switch are made of a reed switch with very high sensitivity. A floating ball switch is a kind of liquid-level control device with a simple structure and convenient use. It has the advantages of small volume and long working life compared with general mechanical switch
WORKING PRINCIPLE: Normal water intake process is activated by the switch below, and the stainless steel double ball water level sensor stops working. The drain is activated by the switch and the lower switch stops working
USAGE METHOD: The action range of the two floats of the automatic water level control switch is 10 mm. If the demand control range is large, two switch combinations can be used, so that there is a large stroke to ensure that the pump does not start frequently
WIDELY APPLICATIONS: The tank float switch is suitable for tank/pump water level control; For fish tank and aquarium systems; Used for water level control of household appliances; Used for water level control of swimming pool, fountain, pond, etc
PLEASE NOTE: The water tank level sensor can not directly control the solenoid valve or high power relay, AC contactor, etc. Small relays are required to transition. A small relay(like HH54P) is needed for the transition
Features: The float switch cannot directly control solenoid valves or high-power relays, AC contactors, etc.A small relay(like HH54P) is needed for transition. The double float switch can be used to control the liquid level of the water tank, pool, sink, fish tank, etc. (drain or water), or to make the upper and lower alarm switch of the liquid level. The contacts inside are made of a reed switch with very high sensitivity. The action range of the two floats of the double float switch is 10 mm. If the demand control range is large, two float switch combinations can be used, so that there is a large stroke to ensure that the pump does not start frequently. Normal water intake process activated by the float switch below, and the float switch above stops working. The drain is activated by the float switch above and the lower float switch stops working.
