Topic tags/keywords: dust collection 220v remote switch inexpensive cheap

Hey all,
New here for posting but have gained a ton of info from you guys before finally signing up. Thank you for your shared knowledge.
I have scoured the ol interweb for a decently priced 220v remote switch for my dust collector project. The best I found was a 220v contactor switch with a 120v coil then using an inexpensive 120v remote switch to kick the contactor. This may still be the route I go.
BUT…... I ran into this!
https://www.amazon.com/gp/aw/d/B07CTL3TG6
A question was asked if it would work for a 14 amp 220v motor to which the seller replied yes. I purchased it because the price is stupid cheap! I will keep you all posted as to how well it works. All the specs check out that it will.
Just thought I might be able to bring a little back to the community.

It says that will work on a pump motor and it is supposedly rated to 40 amps which means that it should work on a DC motor so that could be a cheap way to make your own remote switch.

Looking at the “upgrade’ picture, I see the relay is rated at 1/2HP @240V. I assume your DC has a larger motor?

It all comes down to what the relay contacts can handle. Motor (inductive) loads are among the worst for contact life.

I use a “long ranger” remote switch for my 220v 2hp collector and it has lasted through thousands of cycles without a glitch, but it also has a fairly substantial relay.

Switches like what you have found are amazingly plentiful and quite useful. Worse comes to worse you could aways use it in your original plan with an external contactor.

Relays need to be HP rated. The amp rating at 40A doesn’t mean it will hold up to a motor start up load. The startup load of a 2HP motor for example can be 70+ amps. Time will tell how well that remote switch holds up.

I didn’t notice the specs in the picture. It may not last long on a bigger motor. BTW, you can get what looks like the same remote switch for $2 less here.

I’ll be interested to hear how well it works for you, thanks!

Thanks for the replies guys! Valid points have been brought up. I have a feeling the contact may not be up to snuff but it’ll be worth a shot. And worst case I can absolutely use it with a large contactor switch. Win lose or draw we’ll all find out! Haha

Interesting!

A few years back I installed a 110V Delta shop vacuum and found a similar “deal” on a remote on-off switch at Amazon for around the same amount of money. I thought it was worth a try as a remote switch meant for the purpose was going for nearly $50 at Rockler. When it arrived, I was impressed how robustly it was made. It has been working perfectly now for four years!

Planeman40 that’s great! I’m keeping my fingers crossed. Only potential issue is that this motor is just too much. Btw, I’ll be using the Penn State 2 hp motor on a super dust deputy. Got a smoking deal on a 55 gallon drum, lever lock ring top with rubber gasket AND a fiberboard barrel that fits inside perfectly for $35!!! Those in AZ contact me and I can get you the exact same.

Ok, so I received the remote unit the other day. Upon inspection I was a little concerned about running 220v through it. I decided to go with a $9 220v contactor with 120v coil. Works like a dream! $13 box, $9 contactor, $18 remote switch. $30 total for a legit remote on/off. I’d call that a win!

Nice install! How is the range with the receiver inside the box?

I used a similar remote switch to trigger a carport light and had it in a box which killed the range. Fortunately it had a small antenna wire that worked great when I fed it out through a small hole.

Range is great and super responsive. Anywhere in the shop is no prob. Even tried at the end of my driveway and it works. (In case I want to collect dust in the street! Haha)

Have your say...
