TjernlundAS2SW3 3-Speed Switch for AS2 Transfer Fan, White

The good is that the switch works well. Could do better......no instructions or diagram (on internet), switch plate has no markings for off/on or speed, the switch plate screws don't fit this switch (double stick tape to mount), and the wires should be longer to reach the short distance to the fan and most of the supplied wire nuts didn't hold well so they were thrown away.

I purchased the switch to have low medium and high speed. The low speed is what I would want the high to be. I have asked the company for some resolution. If you want low fan speed not the fan.

Switch works as advertised, but it was difficult for novice to figure out the wiring. I don't know why they did not design a simple plug and play wiring harness

It worked well for the specific application. It price is way high than I expected but I didn’t have choice but to buy this one.

Controls fan speed very well
