Drain Pan Switches

This category features commercial and industrial-grade condensate drain pan switches—also known as overflow safety switches—engineered to provide automated, high-reliability flood protection within high-capacity cooling and refrigeration networks. Designed for direct installation onto the lips of primary or secondary drain pans, or inline within condensate drain lines, these technical float and electronic sensor switches continuously monitor latent wastewater levels. Upon detecting a critical fluid buildup or drain blockage, the solid-state or mechanical microswitch immediately interrupts the low-voltage ($24\text{V}$ AC) control circuit to the compressor or thermostat, instantly halting condensate production and preventing catastrophic water damage to building interiors and structural envelopes. Fabricated with corrosion-resistant housings, hermetically sealed reed switches, and flexible mounting hardware, these assets withstand continuous moisture exposure and vibration. This lineup provides mechanical contractors, HVAC/R technicians, and facility plant engineers with the code-compliant safety controls required to meet International Mechanical Code (IMC) guidelines and secure facility uptime.
