iVAC Automated Vacuum Switch - Push Button Actuator, Auto-Off-Auto Mode, Yellow

I've had the unit for several months now and used it on my chop saw for a full 'deck build' project. It has performed well with no vacuum plugging probably due to the 5 second extended run time feature after making a cut, There's considerably less sawdust cleanup so when I move indoors for winter projects it will make them neater and healthier.

Product works great. Super convenient now I no longer need to turn on my dust collector before using one of my saws. Haven't had any issues with the unit not functioning when using my bosch miter saw or table saw. Currently using this with a 1hp Laguna bflux.

Shipping late, but okay.

There are more expensive options that can be somewhat customized for run time logic, but this one is a better value in my opinion. While the switch logic can't be customized, it doesn't need to be. Works as intended, switching on vacuum with the saw and then leaving vacuum on for ~10 seconds after saw is stopped to catch remaining sawdust. Perfect and simple implementation. The big advantage to this model (and the reason I chose this one) vs others is that it has 2 separate power inputs instead of just one. This gives you the option of using different circuits - one for saw and one for vacuum so you don't trip breakers if both high draw tools fire up at the same time. Very useful. Plus the auxiliary 'always on' plug lets you plug in another tool all in one place. Worked perfect for me while doing some decking where I had miter saw, vacuum and sander all readily available in one place.Highly recommended accessory.

UPDATE: FAILED for no reason. Just stopped working. No odor of burnt electronics, no tripping of house circuit breaker, no tripping of onboard reset breaker. So, I contacted the company "ivacswitch.com" and my email was returned in less than 24 hours. They told me that they have manufactured and sold over 80,000 of these switches with a very low failure rate. They also said that "We have just recently, in the last couple of weeks, discovered a component that fails after some indefinite period of time but usually between 30 and 120 days of use. It never shows up in testing at the manufacturer and it doesn't happen in every component. We are taking steps to eliminate the problem." They then said that they would be happy to replace the switch. So, my original review below stands as written. And the customer service of iVAC is exemplary.Old Review: Plugged this thing into two different circuits, one 30 amp and one 20 amp, then connected my table saw and shop vac/cylone filter into it. It works great. So nice to be able to activate the vac when I turn the saw on - and the delay for the vac is nice as it runs the vac a few seconds after the saw is turned off for a bit of extra dust collection. The company stands behind their product and will honor the warranty without the slightest hassle or question. HIGHLY RECOMMENDED. BUY THREE.
