The Hatco 02.01.029.00 Float Switch with Top Flange provides reliable liquid level monitoring for commercial kitchen equipment. Designed with a black common wire and yellow normally open (N.O.) connection, this float switch helps regulate water levels in compatible units to support safe and efficient operation. It works by using a buoyant float that rises and falls with the liquid level, automatically opening or closing the electrical circuit as needed. The top flange design allows secure installation and stable positioning within the tank. Suitable for replacement or maintenance applications, this component helps prevent overflows, protect internal systems, and maintain consistent equipment performance in demanding foodservice environments.
