Noticed leak and found out existing SS2 failed (luckily we were home). Got it to work after playing with the float, but decided best to replace - did not see the float switch part sold separately but the price was reasonable even though I dedn't need the PVC unit. For better protection, also bought the SS3 and installed in series with an auxiliary pan.SS2 had been in service at least 14 years.

Works fine. A/C repair quoted me $600. I can definitely splice 2 wires!

WARNING... This switch came as a normally closed unit that opens on water rise. This is reverse logic from typical home A/C units. My A/C unit requires a switch that closes when the water is too high. If you install the switch and your A/C runs, you are good to go. If not, easy fix! Remove the C clip below the float (easy-careful), remove the float and turn it upside down. Reinstall the float and clip, and you converted the switch from normally closed to normally open. The switch will close when the pan water rises and cut off the compressor. It may not cut off the air handler (blower), so be sure to test the float positions before you finish the job.Nice looking switch. Now I need to go install mine. Aaarrrggggg!!!IMPORTANT CORRECTION:I was backwards on the switch operation. When down, it completes the red or yellow thermostat wire and allows the compressor to run. When the pan water rises, the switch opens and disables the compressor. The switch float is correct as shipped.

Since the air handler unit for my AC/heat pump is in the attic, a spill would cause water damage to my ceiling.This safety switch provides a little extra piece of mind, knowing that in the event my condensate drain pan were to fill up, the A/C would be automatically switched off until the water level fell down.I installed it on the red line and had just enough line to reach where the thermostat wires reached the air handler unit.One little wrinkle was that I had 2 brown 18/5 thermostat wires. Took a little bit to figure out which one was for the thermostat and which one was for the compressor. I ended up putting the switch in between the red power source in the air handler and the two red wires in the 18/5 thermostat wires. One 18/5 wire was going to the thermostat, the other was going to the outdoor compressor.I noticed that when I activated the switch, the thermostat would lose power. Perhaps switching to the yellow wire would avoid this, but since I have a heat pump, I'm was not sure if it would still operate in heat mode.

My initial thought was to use this switch as the first line of defense. It won't work, thus it can only supplement the draining holes.Fundamentally US HVAC design is flawed on secondary drain pan. The pan is flat, meaning any meaningful water sensing, draining will require "enough" depth. To make things a bit worse, this float works to shut off the circuit with half an inch movement, meaning the best way to install the switch would require touching the bottom of the pan.The enclosed clip sets the switch too high thus I need to flatten the metal clip and drill holes to install it. Since it is hard to drill stainless steel, I ended using the two clipper points as my drilling point, which set this switch a bit up from the bottom.The good news is, the bottom of the pan is filled with debris from Attic, thus getting away from the bottom might help to reduce false alarm. It all depends on how do you want it to work.So, this switch sets a bit too high thus it works only after secondary drain hose is blocked instead of sensing if there is any water inside the pan.
