dust collector remote control

[EricU]

did the lamp remote handle 220v, or did you need another relay?

Hank, the reed switch idea is pretty neat.  I can't decide how to run my ducting, so maybe I should work on that next

Eric, the contactors are bought with a 120V coil, that is what is switched by the lamp remote. The coil, in turn, closes the contacts which powers the DC. If shopping for one, look closely...some of them have a 12V coil.

I know about coil voltages, but when someone says "240v contactor" that usually refers to the coil.  The Europeans must have lamp remotes, but getting one might be an issue, I wondered if he found one.

I have a contactor that would work, but it has a 24v coil.  I am putting in a 12v power supply for the dust overflow detection.  I would like to keep the number of components down. That's what is nice about the 240v coil, dont' need any extra parts unless I want to add some kind of remote to it.  Might come up in the future.  I definitely like the reed switch idea. But I could use a 12v low power relay from that to power the coil.

I did not know that, when I think 240V contactor I assume it's line voltage. It seems like they are always listed that way.

I know, it's annoying on sites like amazon, and not always true.  They should list both. But most contactors are good up to well over 240v, so the most interesting things about them are the coil voltage and amperage.

The square D contactor I plan on using doesn't even say what the coil voltage is on the label.  I had to go look on a generic manufacturer's cross listing because it was hard to find on the Schneider site.

Like Fred said, just find one that has the 110v coil to use with the lamp remote.

I just want to have one power cord. I'll stick with just a mechanical switch before I add a second power cord.

Second cord? For?

Wire it into a 220 switch. Mine is mounted on the wall, as my collector is outside.
Upper left gray box is my remote box.
Pay no attention to the lower right box marked collector. That was for a 3-phase collector I no longer use.

If I'm reading it right.. I use a Long Ranger.. have one for 220 and another for 110

I've had the 220 for at least 20 years

This.

Steve, It looks like your 240V feed has a neutral, none of mine have that feature.
