2 dust collectors with two remotes

[stevem [OP]]

in addition to the camvac, i also use my ridgid shopvac as a dc for some tools, it has a small dust deputy and works great for router table, bandsaw, stuff that's hard to reach with a 4 inch hose.
i want remote control switches for both, the camvac is a 240 v, the shopvac is 120 and i want seperate remotes for both that wont turn both on at the same time! they are at opposite ends of the shop, 20 ft apart
how can this be done?

Did you already try basic remote wall switches and outlets? I use these for my shopvac: https://www.amazon.ca/DEWENWILS-Wire...dp/B07RGN9DY9/ They actually allow me to start the shopvac from two places in my workshop, which is handy.
I don't know if these would interfere with another remote for a different device...

You'll have to find 2 remote switches that have a pairing mechanism like a garage door opener so it only responds to that remote or selectable codes/frequencies. Alsoy, if the unit is made by 2 different companies they usually will not respond to the other's remote.
A slightly different approach is what I have. My 2HP DC is controlled by a home-made current sensing box that responds when the tablesaw, sander, jointer or planer is turned on. For the mitre-saw, router, spindle sander in my shop addition I have a iVAC switch that starts a fairly large CTC shop vac. To get them all to trigger the iVAC they need to be on a power bar plugged into the load outlet of the iVAC. Mine is like or similar to:
iVAC Automatic Vacuum Switch - Lee Valley Tools
It isn't easy to determine the HP rating of many of the cheaper devices and you also need to switch 240V but since you aren't an electrical novice maybe you can hook up a big relay if necessary controlled by the output of a 120V gizmo.
Busy Bee has a 120 and a 240V remote but they aren't cheap - buying both would push you close to $400.

i was considering the lee valley ivac device for the camvac, i'll leave the shopvac(big ridgid) alone for now

I have one of the ivac devices for my shopvac and bandsaw. Works great.

Have you considered a hard wired "remote" switch? Rather than a wireless remote, I wired up 20 ft of extension cord with the switch on the end in a surface mount electrical box c/w a magnet and a loop . I take the switch to the machine I am using so I can turn it off and on at the machine. I also sometimes hang it in the middle of the shop from hooks on the ceiling so it's just a few steps away. I use this for both my shopvac and dust collector, both 120V.

i could probably do that for the shop vac, but my camvac is 240 v, 2+ hp (real hp vs the 6 fake hp of my shopvac)

I built this for my collector. Works fantastic.

Not an electrician but don't know why it wouldn't work for 240V provided you use the correct components. Biggest advantage is no remote to lose or remote batteries to replace.

If I had that, it would be still hanging on the hooks when I'm doing quick cuts, surprising how many cuts are quick cuts.
A permanent safe hard-wired solution is to get a relay with 240V/correct HP rating contacts and say a low voltage AC coil, such as 24V. This is a common voltage for controls on things like furnaces and air-conditioners, etc. Run a low-voltage line to the tools (they can all be on the same 2-wire line) and put a switch across the line at each tool (switches are in parallel) so any one switch turns the tool on/off by activating/deactivating the relay. This can be pretty simple, no-rules, cheap wiring since it is low-voltage.

Sounds like a good solution although in my case all the tools (bandsaw, table saw, planer, jointer, oscillating sander, RAS, and belt/disc sander are all on casters and none are hard piped for dust collection. What prevents me from using dust collection for quick cuts is not turning the DC or shop vac on, it's hooking up the hose. If my tools were stationary I would hard pipe them and maybe use your idea for switching them on/off.

my jointer and planer are pretty stationary(too heavy to move anyway!), tablesaw moves around a bit, those are the three that use the camvac. the shopvac handles the rest because it has a very long hose that is easy to move around

i will be getting the ivac unit with a handheld remote. this will go on the camvac.

For the shop vac, you could go with the Fosman units from Amazon. I purchased the 2 pack and paired both remotes to one of my dust extractors. Interestingly, the manufacturer asks that you not send a unit back for warranty, the will just send you a new one if necessary.
