43914

The Attwood Automatic Float Switch, model number 43914, is a versatile and reliable solution for managing the water level in various types of holding tanks in RVs, boats, and other mobile applications. This float switch is designed to work efficiently with both 12V and 24V power sources, making it a flexible option for a wide range of users.

The switch operates using a float that rises and falls with the water level inside the tank. When the water level drops below the desired point, the float falls, which in turn activates the switch and sends power to the bilge or sump pump to remove the excess water. Once the water level rises back up to the desired point, the float rises, and the switch deactivates, preventing the pump from running unnecessarily.

The Attwood 43914 Automatic Float Switch is constructed from high-quality, corrosion-resistant materials, ensuring a long lifespan even in the harshest environments. The switch is designed to be easy to install, with clear markings on the float and a threaded connection for simple attachment to the tank. The switch also features a built-in diagnostic LED light, which illuminates when the switch is activated, making it easy to confirm that the switch is functioning correctly.

The float switch is suitable for use in various types of tanks, including freshwater, greywater, and blackwater holding tanks. With its durable design, reliable operation, and ease of installation, the Attwood 43914 Automatic Float Switch is an essential accessory for anyone looking to maintain a clean, functional holding tank system in their RV or boat. Whether you're an avid RV traveler, a weekend boater, or a professional mariner, this float switch is the perfect solution for managing your tank water levels with confidence and convenience.
