Quantity: one pieceContact capacity: 50wNumber of switches: 10 to the power of 7Switching voltage: 0-220VAC or O-200VDWorking temperature: -10-100Switching current: 0.5 A (resistive load)Working pressure: 10 ohmsSpecific gravity of medium: > 0.75Protection class: IP40Switch material: SUS304 stainless steelDual float switches can be used to control the level of water tanks, swimming pools, tanks, aquariums , etc. (drainage or water), or make the liquid level high and low, easy to operate.The internal contacts are reed switches with extremely high sensitivity, high resistance and high performance.The float switch cannot directly control solenoid valves or high-power relays, AC contactors, etc. The conversion requires a small relay (eg HH54P).The action range of the two floats of the double float switch is 10 mm. If the demand control range is large, the combination of two float switches can be used to increase the stroke, ensure that the pump is not started frequently, save time and improve efficiency.The normal water intake process is started by the lower float switch, and the upper float switch stops working. Draining is started by the upper float switch and the lower float switch stops working. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
