Feekoon SS2 Float Switch L Shape For AC Drain Overflow
The Feekoon SS2 float switch is designed for air conditioning condensate overflow detection. It functions as a normally closed (NC) switch and can be wired to a VCC or thermostat line. When water overflows, the buoyant float rises, triggering an OFF signal to shut down the system, helping protect floors and ceilings from water damage. Key specifications include a PVC body, operating temperature from -20 to 80°C, and a 5.8-foot wire length. It supports up to 200VDC and up to 1 A, with a maximum load of 10W. This makes it suitable for HVAC drain pan safety in residential and small commercial setups.

Buying Guide: Key Purchase Considerations
- Compatibility: Ensure the switch model matches your vehicle or HVAC unit in terms of thread size (e.g., 3/4″ adapter), connector type, and electrical ratings. Many switches list broad compatibility, but double-check with your exact make, model, and year.
- Electrical Ratings: Look for switches with appropriate voltage and current ratings for your system. Exceeding ratings can lead to premature failure or safety concerns.
- Material Durability: PVC and PP housings offer good corrosion resistance; consider environments with moisture, chemicals, or temperature extremes.
- Application Type: Condensate overflow switches protect against leaks, while clutch/cooling switches manage compressor or fan operation. Choose based on the protection or control you need.
- Installation Ease: Adapters, bushings, and included hardware affect ease of installation. A kit with mounting hardware reduces additional parts shopping.
- OEM vs. aftermarket: OEM replacements (Honda, UAC, etc.) provide direct-fit reliability, while aftermarket options can offer broader compatibility or lower cost. Evaluate the system’s criticality and warranty considerations.
- Maintenance and Replacement: Consider switches with simple inspection and replacement access, especially in hard-to-reach condensate pans or compact HVAC cavities.
- Safety and Compliance: Use switches that comply with applicable electrical standards and maintain proper isolation to prevent shorts or electrical hazards.
