I am putting a relay before the outlet to my 240v dust collector so I can
put a switch in a more convenient place.
The coil on the relay is 240v.
Do I run one hot to the coil, and run the other hot through a single pole
switch back to the other side of the coil?
It is only 60ma, so 14 gauge is fine, isn't it?
Seems to me that this ought to work, with the switch open there is no
circuit; but I don't have much experience with 240v and I just want to make
sure I am not misunderstanding something.
Thanks.

Just in case you aren't too far along with that: you can get X10
remote relays that handle 220V. I have my 1.5HP dust collector
on one. Plug the X10 relay into the 220V socket and the dust
collector into it, then plug one or more X10 controllers into
one or more 120V sockets, and "bling-bling", you're done.
It works well.

Yes, you can wire it that way; it will work just fine.
However, since the control ckt conductors (wire to the switch)
leave the relay box, the wire size will need to match the
branch ckt size (fuse/circuit breaker) feeding the dust collector.
If it's 15 Amp, you can use #14.
Otherwise, you'd have to put *2* fuses in the relay box to protect
the remote control conductors to the switch (or use larger wire).
If the whole thing looks like a big hassle, I'd order a different
relay with a 24V coil and use low-voltage (Class 2) wiring.

I haven't even wired up the outlets yet.
The X10 stuff I have seen was pretty expensive.
Can you suggest an online supply?
Thanks.
Sound like a call to Electro rooter to me

Just remember that you can't put a switch before a mag starter
which are used on most larger DCs and power tools nowadays.

Why not simply pick up a Long Ranger DC Remote?

They work great.
