I hope this is in the right forum.... here goes.
My makerspace is looking at a Grizzly 3hp dust collector that runs on single phase 220 volt controlled with a magnetic switch along with a remote control system.
The system we're replacing we had a home-brew 12 volt system that you could turn on the 120 volt dust collector from various locations via a solid state relay. Of course, this won't work on a 220 volt appliance.
The system comes with a remote control, but that's useless to us as it's a) single point of use, and b) can get easily lost. We prefer to have multiple locations to turn on, maybe even integrate it into our blast gates (opening gate activates 12 volt line to turn on.
I'm familiar with contactors and such, but not sure how to integrate it into the mag switch of a grizzly DC. Any suggestions?
