This is a remote I built for my dust collection system. I only wired in one 240v circuit to my garage a few years ago, never expecting to need another. Vice installing a second circuit, I decided to maximize the existing circuit while designing my remote controller for my dust collection system.

This site is where my inspiration came from. I already had the 120v remote, which was being used for my original HF 1hp blower.

Now, my DC remote controller is using a DPDT 240v relay that requires 120v to activate the coil. It’s designed to keep 240v at outlet 1 whenever I’m not using the dust collector, which my air compressor is plugged into. This eliminates the need to plug and unplug every time I need my air compressor and vice versa. Activate the remote, which then sends 120v to the relay coil, and the relay switches 240v to outlet 2, which my DC system is connected to. I’ll never overload the 240v circuit because it’s only connected to one outlet at a time. I’m extremely happy with it and works just as designed.

One 240v plug and one 120v plug on top, two 240v outlets on the bottom. Everything is mounted to a piece of 3/4 in plywood and mounted high up in the corner.

If you need to share a 240v outlet, this could possibly be useful for you.

Cost, roughly $90. The relay, at $24, was the most expensive part and I had some of the other components already.
