Float Switch for Rainwater Tank mains top up

Low-level Float Switch located inside a rainwater harvesting tank or header tank to activate a solenoid-valve, back-up supply, pump or low-level signal/alarm.


The float switch in the downward position closes the contact between L & L1. In the upward position the contact between L & L1 is opened.

Applications: - filling

  • level-controlled filling (ON/OFF) of tanks; rainwater tank, header tank, intermediary buffer-tank
  • low level signal/alarm of rainwater harvesting tank


The float switch in the downward position activates an external solenoid-valve or pump to supply water to the tank.

The low level alarm or signal can also be used to activate an emergency signal or to display a status on a control panel. It can also be used to trigger a backup supply (e.g. automatic switch-over from rainwater to well-water, if rainwater tank is empty).


Connection is either possible directly to solenoid-valve, pump or indirectly to the rainwater harvesting control panel.


The float switch for mains water top-up is an emergency back-up in order to ensure continuous automatic supply at a rainwater harvesting system or water-supply system, in case the primary water supply source (e.g. low level inside rainwater tank) is not available.


Brown = L; phase/power supply

Blue = L1; to solenoid-valve, low level alarm, back-up supply or rainwater control panel

Green/Yellow = PE (earth conductor)


SAFETY NOTICE: due to submerged operation, a float switch with earth conductor (PE) is recommended at any installation with up to 250V. All float switches supplied by GEMGATE Limited are equipped with an earth conductor!
