SPI 20A706-LY Mercury Float Switch with 15-Foot Cord

The SPI 20A706-LY is a professionally rated mercury float switch designed to deliver accurate, dependable liquid level control in demanding pump and drainage applications. Built to exacting standards, this unit combines rugged materials with a proven mercury-actuated switching mechanism to ensure consistent, bounce-free operation over thousands of cycles.

Engineered as a heavy-duty mercury float switch for septic and wastewater environments, the SPI float switch features a 15-foot float switch pump cord that provides ample reach for deep tank installations without the need for extensions. The 15ft cord on this liquid level float switch is constructed from durable, moisture-resistant jacketing rated to withstand continuous submersion. As a sewage pump float with a 15ft cord, it accommodates a wide range of mounting depths while maintaining a secure, reliable connection to the control panel or pump motor.

This switch is well-suited for residential and light commercial septic systems, sump pits, lift stations, and effluent pump basins where dependable automatic level control is essential. It is compatible with most standard submersible sewage and effluent pumps and can be used in pump-up or pump-down configurations depending on installation orientation. The mercury switching element provides a clean electrical contact rated for motor loads, making it a dependable choice for automatic pump cycling where float bounce or false triggering from mechanical switches could cause premature pump failure. Ideal for contractors, maintenance professionals, and DIY installers looking for a long-lasting, low-maintenance float solution.
