Remote Switches for Dust Collectors
As many know, turning a dust collector(s) off and on can be a nuisance. The fact it’s across the room is bad enough. Then there is that, no mater how you position it, either the ports are in the wrong position, or you have to reach over or around hoses or the collector to get to the switch. Even if the switch is on the right side, you have to reach down to the motor to get to it.
To solve the problem, I removed the switch from the motor housing and installed it in a box at the end of twelve gauge power cords.
The box for my large collector is on the end of ten foot cords, so it can be relocated to tools near it. The smaller collector has enough cord to allow me to position anywhere on the metal can.
To secure the switch box to my saw, or in a convenient place on the collector, I use rare earth magnets that come center-drilled and counter sunk, allowing use of flat head screws to secure them.
On my big collector, I used three small magnets (K&J Magnetics part number B884DCS). They work, but I do need the three and the box can still move, if I get a bit too aggressive pressing buttons.
When I ordered the smaller magnets, I also ordered two larger magnets that have nearly one hundred pounds pull (K&J Magnets, items number MMS-A-X8). I used that one on the smaller collector and it stays put – very put.
The reason for two cords is, 240 volt equipment must have both legs broken/connected, when turning the equipment off and on. My big collector is running 220, so had to be done that way. The little one is running 120, but I plan on adding another 220 line for it and I’d have to add the other cord, so I did it now, rather than have to redo everything later.
It’s nice to be able to, for example, just reach to the left of my band saw to turn the collector off and on.
