FloatSwitch

In marine, RV, and mobile water systems, reliable automatic pump control is essential for safe and efficient water management. The Newmao NMFS11-20 Float Switch is designed to provide automatic pump operation by responding to changes in water level, helping reduce the need for manual monitoring and operation.   The NMFS11-20 is a compact and practical solution for applications where a pump needs to start or stop automatically according to the water level. When the water level rises, the float mechanism activates the switch, allowing the connected pump to operate. As the water level falls, the switch returns to its original position and stops the pump. This simple operating principle makes it suitable for a variety of water-management applications.   Designed for 12V, 24V and 32V Systems   The NMFS11-20 Float Switch is designed for low-voltage DC electrical systems commonly found in RVs, boats, yachts, and other mobile applications. According to the product specifications, the switch supports up to 20A at 12V DC, 12A at 24V DC, and 8A at 32V DC.   This voltage compatibility allows the same float switch platform to be used across different electrical system configurations, giving distributors, OEM customers, and system integrators greater flexibility when selecting components.   Automatic Pump Operation   One of the key advantages of a float switch is its ability to automate pump operation. Instead of requiring an operator to continuously monitor the water level, the switch can activate the pump when a predetermined water level is reached.   This makes the NMFS11-20 particularly useful for applications such as bilge water management, drainage systems, sump applications, and other automatic water-removal systems. For equipment manufacturers, integrating an automatic float switch can also help simplify system operation and improve overall user convenience.   Ignition-Protected Design   For marine and RV applications, electrical safety is an important consideration. The NMFS11-20 features an ignition-protected design, making it suitable for applications where electrical components may be installed in environments requiring additional protection against ignition sources.   The switch is supplied with approximately 1 meter of wire using 18 AWG cable, providing convenient installation for many common system configurations. Its compact construction also allows it to be integrated into limited installation spaces.   A Practical Solution for OEM and Distribution Customers   For B2B customers, product consistency, application flexibility, and straightforward installation are important when selecting a float switch. The NMFS11-20 provides a simple solution for automatic pump control without adding unnecessary complexity to the system.   Whether used in RV water systems, marine bilge systems, drainage equipment, or other DC-powered pumping applications, the Newmao NMFS11-20 Float Switch can serve as a practical component for automatic water-level control.   Newmao continues to develop water-management components for marine, RV, and mobile applications, supporting OEMs, distributors, and system integrators with reliable products and application-focused solutions.   Product Highlights Model: NMFS11-20 12V / 24V / 32V DC compatible Maximum current: 20A @ 12V, 12A @ 24V, 8A @ 32V Approx. 1 m wire length 18 AWG wire Ignition-protected design Suitable for automatic pump operation Ideal for marine, RV and water-management applications
