SENCTRL Automatic Vacuum Switch Allow Power Tool/Table Saw to Turn Vac Cleaner/Accessory On and Off Automatically, Load Sensing, On Delay Prevent Circuit Overload, Shop Dust Collector Off Delay

This is a compact, well designed, and sturdy unit which works exactly as described. The vacuum outlet starts almost immediately after the saw starts and runs a bit after the saw stops - a useful feature.

Works great

Turns ona nd off when it should. No complaints.

A must have if you work with chop saws or table saws. Never forget to turn on the vacuum again. With this set up just cut and go. The vacuum works automatically. A must for any shop or job site.

Works as it should. Nice small plastic box. Robust power cord. Two minor issues: The mounting screws that are provided are worthless to use in wood, they strip even with pre drilled holes, so you need to use your own screws. Also, the on-off switch is too close to the outlet, and with my shop-vac plug, it is difficult to turn the vacuum on manually. I see no reason for it to be this close. They need to move the outlet about 1/4 inch further away and then it would be fine.

After 60 years - yup, 60 - I decided to set up turning table saw on and off easier - why it was difficult is a long story! This switch works very well. Looks good too. Strongly recommend.

UPDATE 2: After only a couple months, my replacement crapped out (again). Not only does the switched tool outlet not power on when the main tool is activated, no outlet works. It's a pile of junk. I'm happy that Senctrl proactively leaned forward and replaced my original unit, but the fact that two units in a row failed means I simply cannot recommend this for any serious use. I guess if I were more electrically savvy I might be able to crack this open and replace some defective parts (might be that the defects are replaceable by cheap but robust parts), but this hardly makes this a recommendation to buy. If I were you, dear prospective customer...please go shopping elsewhere (I have). UPDATE: Senctrl responded to my negative-ish review by offering me either a refund or a replacement product. I chose the replacement b/c a) I just wanted an auto vac switch that worked, and b) I do understand that some products simply fail earlier than expected, and was more than willing to give 'em a second chance. I am happy to report that the replacement arrived w/in a few days (Amazon normal), and works perfectly upon installation. I'll update this review if the product appears to fail in an unreasonably short timeframe, but for now, kudos to customer support for standing behind their product--I'm pretty sure that I got the replacement outside the official warranty, and for no questions asked. Happy days. //original review follows// I added this to my table saw setup, so I could simply turn on my saw and the attached shop vac w/ cyclone separator would start automatically, without me having to step around to switch it on. Worked like a charm, and I especially liked the feature that kept the vac powered for seven seconds after the saw stopped, to gobble up all those particles still swirling around. All was good for about five months, until one day it simply stopped working. Cold. More specifically, rocking the switch to "off" indeed means that the vacuum won't start. And the "(always) on" position works. It's just that the justification for this $30 switch, the "auto" position fails to power on the vacuum at all. Now, I can work around this by simply switching the rocker to "on" before I power up my saw, but again, this totally defeats the purpose of a little pricey switch box to begin with. And, yes, I verified the issue was not my vac by plugging in another device into the vac port. Clearly something in the unit fried, and this highly disappoints me. It's a solid state product and should last for years and years. Five months? Look elsewhere IMHO.

This vacuum switch works great. Delay is great to prevent tripping breakers.

Definitely a product every contractor should have!

This worked exactly as specified. It’ll will be a great addition to any shop dust collection. Well made works perfect. I highly recommend it.

Me gustó el diseño de este interruptor. No sabía que existía algo que pudiera encargarse de encender la aspiradora automáticamente y que, además de eso, pudiera proteger en algo mi instalación eléctrica. Hubo dos detallitos que me agradaron aún cuando pueden parecer insignificantes; el primero fueron los taquetes y las pijas para su instalación, el otro; que el interruptor estuviera sellado dentro de esa burbuja de hule. El cable es cortito. Debe haber unos 30 cm entre el inicio de la clavija y el aparato. En mi caso es más que suficiente. Hay un LED en la parte de abajo para poder estar seguros de que todo está en orden y funcionando. Espero que este funcionamiento sea prolongado y que dure mucho tiempo. Me agrada bastante la marca DeWalt, esta combinación de colores no podía haber sido más adecuada para mi pequeño taller. Estoy contento con este aparatito. :D

excelente producto

Good
