Hello,
I'm looking for a schematic for an automatic switch which you place in series with your router, sander,... As you switch on the equipment it automatically swith on the dust collector or shopvac. I suppose it is based on current transformer,but I want to use few parts to trigger the relay around it (the less the complexity, the more the fiability. If someone can help sending the schematic or giving the link to a web description
