Sje-rhombus 1001983 Float Switch Sewage Pump Control

Product Description

The SJE-RHOMBUS 1001983 is a mercury-activated, wide-angle float switch designed to control submersible pumps in non-potable water and sewage applications. Also identified by the model designation 20SSD1WP, this switch is rated for pumps up to 1 HP at 120 VAC and up to 2 HP at 230 VAC. The wide-angle design allows for a broad activation range, reducing nuisance cycling and improving pump reliability in sump, sewage, and effluent systems. Licensed plumbers and pump service technicians are the primary installers for this type of control switch.

This float switch is suited for residential and light commercial wet-well and sump applications where automatic pump activation is required. It is commonly used in sewage ejector systems, effluent pump stations, and non-potable water sump installations. The switch activates the pump as liquid rises to the trigger point and deactivates it as the level drops, providing hands-free level control without a separate controller or panel.

Key Features

• Mercury-activated switching mechanism for reliable, bounce-free contact closure
• Wide-angle float design provides a broad activation range to reduce pump short-cycling
• Rated up to 1 HP at 120 VAC for single-phase residential pump applications
• Rated up to 2 HP at 230 VAC for higher-capacity pump installations
• Suitable for non-potable water and sewage service environments

Compatibility

Designed as an OEM-style replacement float switch for submersible sewage ejector and sump pump systems requiring mercury-activated, wide-angle level control in non-potable water service.

Installation Notes

Installation should be performed by a licensed plumber or pump technician familiar with wet-well and sewage ejector systems. De-energize the pump circuit at the breaker before handling any wiring or float switch connections. Secure the float switch tether at the correct depth to achieve the desired pump-on and pump-off levels, following the pump manufacturer and local plumbing code requirements. Never use this switch in potable water or hazardous-location applications.
