These float switches are designed for civil and industrial applications that involve controlling dirty water levels, such as sewage or industrial wastewater.

Each unit features a one-piece, blow-moulded polypropylene casing with a fixed internal counterweight positioned at the cable exit point. The regulator contact is centrally located within its own watertight chamber, which is insulated from the outer casing by injected closed-cell foam.

This construction provides enhanced protection against moisture ingress while also thermally insulating the watertight chamber. By eliminating condensation, this design ensures long-term reliability and stable operation in demanding environments.
