Recently I’ve completed several improvements to dust collection in my small shop. One of the goals was simple, to use the DC at all times. However, I had a floor switch for the DC that I had to walk to and press to turn on DC.
Purchased this unit at Rockler for ~$ 30. Installation was less than 5 minutes. I have it connected to a HF 2hp DC.
Have no problems with it and now I carry the remote with me using a clip. Not only do I use the DC more often, it is a timesaver too.
