## Overview

The Universal Secondary Drain Pan Condensate Float Switch (CS-3) is a precision-engineered magnetic reed switch designed to prevent water overflow in HVAC systems. Featuring a rust-proof stainless steel bracket and pre-wired 6-foot lead wires, it fits drain pans with a minimum depth of 1-3/8 inches. Compatible with a wide range of models, this compact, IP54-rated switch offers reliable, easy installation and long-term flood protection for both commercial and residential applications.

## Description

Flood Prevention Switches are simple to install, easy to service and extremely reliable. As water level in the auxiliary or main drain pipe rises due to a clogged air conditioning condensate drain, the switch shuts off the systemâ thus preventing water from overflowing and causing damage to doors, walls and ceilings. At the heart of the switch is a durable yet precise magnetic reed switch. Constructed of materials that will not rust or stick, the switch operates smoothly every time.
