I guess this would be more an electrical project than a woodworking project, but I thought I would post here as some might want to make something similar.

I wanted a remote switch for my Harbor Freight dust collector. I looked at the ones in woodworking catalogs; however, I was concerned about their reliability, as may people have said they die after a year.

Falling asleep one night, I came up with a way to easily make one. In short, I used a $10 wireless remote switch to run a contactor relay, which can handle the power demands of the dust collector. The good thing about this design is that if anything dies, it will be a cheap & easy fix. This design could easily be modified to power a 220V dust collector.

How hard was it to wire? Well if you can barely wire an outlet, this is NOT the project for you. If you can easily wire a 3-way switch and can understand my drawing, it is relatively straightforward.

Here is a link to MUCH more information.

Below are some pictures

Cool setup…. I did the same thing with a 110v contactor and a remote light switch controller. Works great
Your water tite control box looks like what i used to see on the commercial dishwashers and garbage disposals i used to work on

Steve -

Click on the link and it has a lot more information.

My actual relay was an EATON C25DND330A, which is given to me and designed to run a 3 pole motor. However, if you search, you will find some much cheaper and easier relays to find and use.

Another idea would be to go with X10 remote control modules.
Their site is X10 dot com.
All you do is put a module in the wall outlet then plug you appliance into the module.
Another module with an antenna acts as a receiver and you can have the multi channel controller
in your pocket. It can also be used with a timer module to make lights go on and off on schedule.
I’ve been using them for years.
