The DIVERSITECH TP-CS3 is a condensate drain pan overflow switch designed to protect residential and light commercial spaces from water damage caused by clogged air conditioning condensate drains. When the water level in a drain pan or auxiliary drain pipe rises to the activation point, the switch cuts power to the system before overflow occurs. At its core is a magnetic reed float mechanism built from rust-resistant, non-stick materials for consistent, long-term operation. A pull-to-test lever allows technicians to verify correct installation without waiting for an actual flood condition. An integrated LED indicator notifies both homeowners and service technicians when the switch has been activated.
The TP-CS3 clips directly to the drain pan wall, making it well-suited for residential split systems and packaged units where pan-mount installation is preferred. The activation level is field-adjustable by repositioning nuts along a threaded shaft, giving installers flexibility across varying pan depths and drain configurations. Six feet of lead wire is included to accommodate a range of wiring routes without the need for extensions in most installations. An internal surge protector is built in to reduce the risk of nuisance shutdowns from voltage spikes on the low-voltage control circuit.
Designed as an OEM-style replacement or new-installation condensate overflow switch for residential and light commercial air conditioning systems with standard drain pans.
Installation is typically performed by a licensed HVAC technician as part of a condensate management system on a split or packaged AC unit. Always shut off power to the air handler or furnace at the disconnect before wiring the switch into the low-voltage control circuit. Clip the switch securely to the drain pan wall and adjust the float activation height before restoring power. Use the pull-to-test lever to confirm the switch interrupts the control circuit correctly before closing up the unit.
