DiversiTech® WS-1 Wet Switch™ Condensate Flood Detector – Technical Product Information

The DiversiTech® WS-1 Wet Switch™ is a solid-state flood detection control designed for professional HVAC installations to protect structures and equipment from condensate overflow and moisture damage. Engineered for precision moisture sensing, it automatically interrupts the control circuit to shut down air conditioning or refrigeration equipment when water is detected in the drain pan or surrounding area. The unit features an integrated test and reset button for field verification, a high-visibility LED status indicator, and a quick-drying absorbent sensor pad. Compact, reliable, and easily installed, the WS-1 provides a dependable safeguard against property damage resulting from condensate or drain leaks.
