As my new vac setup puts the vac way under the bench, I was thinking which is more convenient, a nice big paddle switch under the bench top, or a foot switch? Don’t need remotes and don’t really care for “automatic”.

If the vac is dedicated to a single machine, a foot switch where you normally stand to turn the saw on and feed is probably the way to go. Harbor Freight sells a locking foot switch that would be perfect for that (don’t get the momentary one by mistake). My vac is used on multiple machines and clean up so a simple remote works better for me. The remote is on a large Masonite fob that I stick in my pocket with the remote hanging out, making it easy to reach. It usually stays there for the entire time I am in the shop but I painted the fob red to make it easier to find after laying it down on a bench somewhere, though I try to always leave it in the same place to cut down on the swearing when I cannot find it.

Yes Mark, the question is which does one find more convenient, the foot switch or a fixed switch. ( with proper rated cord and strain relief)

Nathan. I have a remote on the dust collector. Big hunky remote, so I have velcro pads stuck to my various machines so I just move it around. Most everything I would use the shop vac for is either cleanup, or hand power tools all at one location on my bench. I guess a remote is a little easier. I like your big fob idea.

The only time when the remote with fob is a little bit of a problem is when cutting something on the saw that takes 2 hands to hold. While you still have to free one (usually left on mine) hand to start the saw, a foot switch to start the vac might be easier, depending upon how convenient the spot where the paddle switch would be mounted.

Mount it over the bench, do you can hit it with your forehead.

Eeyore almost nailed it. I think I am going to get the HF foot switch and mount it where I can bump it with my hip.
Need clear space above the bench for working on big stuff.

Just solved my cyclone to bucket hold down problem. Bungee cord. 2 gallon bucket so it fits under the outfeed/workbench. Now if I every get my 6 inch duct. Ordered it though HD. Said I would get it last Monday. Notifications continued until about 7 PM when they said it was delayed until Friday. Then HD said ity would be delivered by Friday end of day. Never came but got a FEDX number. FEDX said labels were generated Friday in Texas, but have not received the ducts yet. Things get delayed, sure. Seems their communications has some issue. I have no idea when they are coming.

If you would want a wireless off / on switch, just about any low current wireless light switch (think Christmas tree light switch) can be used to pull in and drop out a 120V contactor relay.

Buy two pole contactor (~ $10 on amazon), low current switch (~$8), an old extension cord and one is in business. If one wants really small, you can take the wireless switch apart to get to the business side (if you feel comfortable)

The Main Safety point is to use the wireless switch as the pull in / drop out mechanism on the contactor. DO NOT attempt to use it to switch high current loads. Too many bad things can, and will, happen.

The process is:
Cut the extension cord allowing for enough input and out put lengths.
Connect the whites to the a common side of the contactor, Black to the other side. Want to ensure that they are on the same long side of the contactor. The “Plug” end of extension cord goes to the LINE side of the contactor (always hot), the “Receptacle” side of extension cord goes to the LOAD side (switched).
Connect the LINE (think wall) side of the low current switch to the LINE side of the contactor (equivalent to plugging into the wall outlet) and connect the output to the pull in connections on the contactor.

The wireless remote will close the internal low current switch (powered from the line/wall side fo the contactor), which allows the solenoid to activate (very low current), closing the high current connections on the 120V line. When the wireless switch is turned off, the internal low current switch opens, releasing the solenoid, and the high current 120 line is opened due to the spring in the contactor.

To ensure safety, then place your switch assembly inside a non-conducting box. Think Tupperware or the like. Most of the low voltage switches have an indicator light that you can see to know it is closed and the 120V is energized!

Hope this is considered helpful.
