WIRING GUIDE
FS-2359 Dual Action Float Switch
The dual action float switch allows the control of a solar water pumping
system to start and stop the pump based on the water level in a tank.
This dual-action float switch can be wired as either Normally Open (NO) or
Normally Closed (NC). The use of either NO or NC is based on the pump
controller used or the system configuration. Review the controller manual to
make that determination.
- NO (Normally Open): Only use black and blue wire. Cut off the brown wire
- NC (Normally Closed): Only use black and brown wire. Cut off the blue wire.

Float Switch Wiring
The dual action float switch can be wired for either Normally Open or Normally
Closed. This function is determined by the wires used. Only 2 of the 3 wires
will be used.
The included counterweight is used to hold down the float switch cable.
Install counterweight onto a 15-meter cable prior to connecting to the pump
controller. Position it on the cable and adjust so the float switch is in the
up position for the desired water level. The float switch cable can be
shortened as needed or extended with proper waterproof splicing.
