Float Switch Liquid Level Sensor

Float switch liquid level sensor for detecting high or low fluid levels in tanks, aquariums, or hydroponic systems. It automatically triggers pumps, alarms, or indicators based on the liquid level.

The switch can be easily configured as Normally Open (NO) or Normally Closed (NC) by inverting the float ball orientation. Important note: The switching current is low (max 0.5 A). To control higher loads (pumps, motors), you must use an intermediate relay or contactor, which is not included.
