Featuring a rust-proof magnetic reed switch and a snap & go stainless steel bracket, it fits pans with a minimum depth of 1-3/8 inches and replaces a wide range of legacy models. With pre-wired 6-foot lead wires and a lightweight design, it offers reliable flood prevention to protect your property from costly water damage. ## 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 systemβ€”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.
