Automatic Vacuum Switch, Ortis Dust Control Autoswitch for More Power Tools, Delay Vacuum On/Off to Prevent Circuit Overload and Tripping, Adjustable Actuation Threshold

I love this Otis automatic vacuum switch. It’s easy to use and works perfectly every time. I use it for my shop vac so can’t comment on connecting it to a dust collection system. I looked at a few of the other switches before purchasing this one and none were suited for my needs. Others were two plugs for vacuums and only one for tool. The Otis switch is designed so that two tools can be plugged in at once with the ability of either one to trigger the vacuum. I’ve used it on a variety of tools including my job site table saw and a small router table without any problems. I’ve dragged it around, dropped and stepped on it multiple times and still no issues. Lately I seem to be using my miter saw most often so the switch is now mounted next to the saw but still accessible so that I can reach it and plug in whatever other tool I may need. I like having the option to turn the switch to auto, off, or on. The shut off delay times also come in handy depending on the circumstance. I plan on buying a few more of these switches so that I can mount permanently next to stationary tools and have at least one that will be mobile so I can drag it around as needed.

I am using this to start my shop vac from the mitre saw. It works as expected and I really like the ability to adjust the lag time before the vac shuts off after sawing.

This automatic switch works awesome. You just have to remember to not start cutting before the vacuum turns on. Easy to use, good price and I would go for this model since you are able to modify it to your liking. Definitely recommend!

Works great with a vacuum and saw. I use this to automatically turn on a shop vac connected to the dust port of my saws when the saw is activated. It turns on the vacuum instantly and helps me keep sawdust, and cleanup, at a minimum.

Great price and does exactly as should

I built a workbench that has my table saw on one end and my miter saw on the other. Having both of them plugged into this device along with my Dewalt shop vac has been a great timesaver. I no longer have to plug/unplug a saw and hook it back up. I like that there is a time delay which clears out all the sawdust once the saw has stopped.Definitely one of the best purchases for my small workshop in the garage.

I've bought two of these now and they make things SO much easier. Great way to manage a vacuum for dust collection.

I’m amazed with this product,it works perfect
