I am new here. I have spent a bit of time searching the archives for something like this but haven’t found the answer yet… Many people mentioned being satisfied with the Sears and the Rockler units. Several people also mentioned that they had made their own devices, but I didn’t come across any plans or descriptions that were detailed enough to actually make one for myself…. anyone care to share?

Here is what I want: I am making a mobile vacuum system on a cart – using a shop vac and a pre-collecting drum that I can wheel around my shop and hook up to power tools one at a time. I want to make a switch that turns on the vacuum when I turn on the power tool that I am using and then allows the vacuum to stay on for a few seconds after I turn the power tool off. The problem is that I want the tool to be plugged into THE CART itself, not back at the outlet where the vacuum is plugged in—which is what the sears and rockler switches require. This way, the vacuum cart essentially becomes an extension cord for the tool. I’d also like to be able to run the vacuum by itself as well…. so the switch needs to have “auto/on/off” functions.

I hope that made sense…. thanks a bunch! I will try to post pictures of my vac setup when it is all complete…

Thanks for the link lew! Now I just have to learn how to read wiring diagrams….. haha.

Comments or advice from anyone else who has successfully (or unsuccessfully) built something similar are welcome.

I did this by simply mounting a power strip on the cart my dust collector is mounted on. The iSocket from Rockler plugs into the power strip.
