Rectorseal96100 AquaGuard 1100+ Switch for Metal Pan, Tan

Well, I tested this by clipping it onto the side of a plastic food storage container and gradually filled the container with water at my sink, while watching the wires with a resistance meter. It waited until the VERY last minute, but it did trip before water spilled over the side. So, when you install this make really sure you push it all the way down so the brim of your pan is seated all the way up into the mounting bracket. If your pan isn't deep enough for that (i.e., if the switch is stopped by the bottom of the pan instead of by the bracket, then be sure you do your own test; I'd worry in that case.I installed this in the drain pan for an Aprilaire whole home dehumidifier - installation was a breeze. On the wiring panel for the Aprilaire there are two terminals for float switch, and initially there is a small jumper between them. So you want to use the "common" and "normally closed" wires of the switch, which are the long one. I just removed the little jumper and wired the switch wires in its place - job done.

Saved me $100 by not requiring HVAC tech to install.

We needed to add one of these for the sale of our house. It came quickly, was easy to install, and took care of the issue. Sale completed!

I like this part

Muy facil de instalar y muy buena calidad👍🏼

This switch gives me peace ofMind that my A/C works properly.

Justo lo que necesitaba

I replaced a failed float switch with one of these and was very easy to install. Just attach to the pan and connect the wires. The switch was easy to test and shut down the unit when the test pin was pulled and also when the water test was done.
