Teel 3288956Y-NC 3L613 Piggy Back Float Switch

The Teel 3288956Y-NC 3L613 Piggy Back Float Switch is a mechanical float switch that automatically starts and stops pumps based on liquid level, enabling automatic operation via a piggyback plug connection. With a tethered float and normally closed (NC) contact, it installs as a direct replacement in sump pumps, sewage pumps, effluent pumps, dewatering pumps, and other utility pumping gear to provide automatic liquid level control. Manufactured by TEEL, this unit carries MPN 3288956Y-NC and is also referenced by alternate part number 3L613. It is compatible with water, wastewater, effluent, and non-corrosive liquids and is suited for commercial, industrial, municipal, and utility pumping systems. Maintenance teams, OEMs, pump service technicians, and system integrators use this float switch for repairs, preventive maintenance, system upgrades, and replacement of worn or failed liquid level controls. Common replacements include TEEL 3L614, Little Giant 599118 RFSN-6, and Zoeller 10-0035 piggy back switches.
