The SKF float switch gives sump pumps, submersible pumps, and general water-level control a robust, cut-to-length solution — adjust the trip point simply by sliding the weight along the cable rather than needing a fixed-length pre-set switch. Choose the standard PVC cable for clean water, or the Neoprene SKF-N variant where dirty or contaminated water would degrade a standard cable.
High quality replacement item for use with sump and submersible pumps. Or for general water level control and indication.
- Simple assembly, cable can be cut to length
- Adjust the requested operation interval with weight
- Different cable length options up to 10M
- Changeover contact N.O. + N.C. (3 cables cores)
Standard SKF Float Switches have PVC cable (not suited to dirty water).
Select SKF-N for Neoprene cable (suitable for dirty water).
Wiring Instructions
The attached flexible cable contains the following three cores.
Operation
Black and blue have continuity when the float is level i.e. water is present.
Black and brown have continuity when the float drops i.e. empty no water.

Frequently Asked Questions
How do I adjust the trip level?
Slide the weight along the cable — moving it further from the switch body increases the operating interval (the water level swing before it trips), while moving it closer narrows the range.
Should I choose PVC or Neoprene cable?
Standard PVC suits clean water applications; choose the SKF-N Neoprene cable variant if the water is dirty, contaminated, or contains chemicals that would degrade standard PVC over time.
Can I shorten the cable myself?
Yes — the cable can be cut to length during installation, though this will also affect where the float weight sits relative to your fixing point.
Is this suitable for submersion?
Yes — IP68 rated, designed for continuous submersion in sump pits and pump chambers.
Industry Applications
- Sump & submersible pump control — automatic pump start/stop based on water level
- Water & wastewater level control — high/low level detection in tanks and pits
- Dirty or contaminated water applications — Neoprene cable variant for harsher water conditions
