Automatic Dust Collector Switch #5: The Evolution of My Automatic Dust Collector Switch System

Interesting but why not post something instead of just read this link and it requires one to download a file.

Typically, I do not even look or respond to blogs which say read this or watch this video.

Thank you for your input. I apologize. It should not require a download. It just points to a pdf file of the article I wrote with pictures and should be readable from a standard browser on any device. I wrote the article on my iPad while offline on a trip. It took several days to complete and to get the formatting correct. I didn’t see a way to post the pdf directly to this blog but wanted to share it with the community. When I have time to sit at my computer, I will try to copy and paste the article and upload the pictures.
Thanks again.

While I also prefer things posted directly to the forum, I understand why you did it this way.

I read the PDF and downloaded it for further study.

Seems like a good progression. I’d like to see cheaper current sensing switches, and I’m sure they are possible, but your final-for-now version looks very nice.

Thank you, Paul. I just found THIS ONE for a great price.

I’m thinking I could put one together for less than $5, but I may be mistaken. I would use a relay of the type used in electric stoves along with a little bit of other circuitry – a little low-current solid state relay just to drive the coil of the main relay and a little sensing circuit.
