I have never had a remote switch for my dust collector (2 hp 110v Harbor Freight w/ Thein baffle and Wynn filter) but after using an inexpensive remote multichannel switch I purchased from Amazon about a year ago to control lightening in our living room, I decided to try and make a dust collector remote switch .

The remote switch I purchased from Amazon comes in a variety of configurations depending the number of remote switches and controllers needed, and they are sold under several multiple brand names (Beastron, Etekcity, etc) but similar to this one in the photo below. The main limitation is that they are limited to about 10A or less.

To get around this I wired one of these remote switches to a suitably large 110V relay (30A) and put the whole assembly in a double gang outlet box. The remote switch is used to trip the relay, which in turn switches on one of the outlets connected to the dust collector. It works very well in my shop.

The Etekcity remote and switch go for about $20 or so on Amazon, and a you can find 110V 30A relays on Ebay for less than $10 each. A few more dollars for an outlet box, outlets, and some cabling is needed to complete the assembly. The Etkcity controllers can accommodate up to five remote switches, so if you need that many, the cost per switch is even less.

If you are like me you will find your setup very handy indeed. Don’t really follow why the extra relay and wiring was needed. My shop vac based dust collection system has been hooked up to one of those auto switches that senses a load and turns the vac on when the tools are started. The only drawback is that if you’re using a tool on the other side of the shop you have to walk over and manually switch the vac on or turn the tool on to start the vac for that quick tidy up after using the tool. Then as a Xmas present member Scott gave me a similar set up as yours with 3 modules and a 3 button remote from HF. Much handier especially when I just want to run the vac to clean up dust and debris without turning a tool on or walking to the other side of the shop to turn the vac on. I wear the remote around my neck on a short rope. It is rated at 15 amps. One switch controls the main vac, another the small 5 gal vac hooked to the miter saw and the third to my overhead fluorescents.

I recently installed some additional lighting in my garage shop and wanted to use the garage opener outlet on the ceiling to power them. Problem was the outlet is 12’ up and I didn’t want to use a bunch of extension chords or wire a switch. So I bought a wifi controlled switch on Amazon and can control my lighting now with my phone. I was going to do the same thing on the dust collector but ended up picking up a 220v DC that came with a remote switch. The switch I bought is rated for 15 amps so it would probably work for a 110v DC on a dedicated circuit.

You only need the relay is you are going to be drawing more current than what the remote switch is rated for, typically 10-15 A.

Thanks to both of you for this information. It is very timely as my old craftsman auto switch bit the bucket and I have looking at options to run a new dust collector, my regular shop-vac and a small shop-vac for my miter saw. This solution would be significantly cheaper than new auto switches. The only challenge I am going to have is remembering to turn on and off the dust collection before running the various tools (yes I am spoiled!).

Have your say...
