A float switch is a device used to detect the level of liquid. A very common application is in sump pumps and condensate pumps where the switch detects the rising level of liquid in the sump or tank and energizes an electrical pump which then pumps liquid out until the level of the liquid has been substantially reduced, at which point the pump is switched off again
1. Electric switch used in water systems, start and stop the pump automatically
2. Examine the water automatically, stop the pump in the case of water shortage, protect the pump from damage caused by dry-running.
3. Completely replaced traditional pump control system composed of pressure switch, pressure tank and check valve, etc.
