Little Giant 599118 RFSN-6 Piggyback Mechanical Wide Angle Remote Float Switch

The Little Giant 599118 RFSN-6 is a piggyback mechanical wide angle remote float switch designed as a direct-acting, in-line control system for automatically controlling wastewater, effluent, and sewage pumps. Compatible with pumps up to 1/2 HP at 115V or 1 HP at 230V, this switch can convert any manual pump into a fully automatic system — no control panel required.

The float body features a non-corrosive PVC plastic construction, rated for use in liquids up to 140°F, making it well-suited for demanding sump, sewage, and effluent applications. Heavy-duty epoxy-sealed contacts and cord conductors ensure long-lasting, reliable performance. The wide angle float design is not sensitive to rotation (no defined "up" side) and resists interference from turbulence, allowing it to function effectively even in tight or turbulent installations.
