Unique Current Sensing Technology. If the tool motor connected to the 'A' port exceeds 30W, the vacuum connected to the 'B' port will automatically delay 1s to turn on, which helps prevent circuit overloaded by large current if tool and vacuum power-on at the same time. Make the Work More Effective. Automatic delays 1s to turn on the vacuum when you start your tool, and delays 7s to turn off the vacuum to clean the inlet tube when you complete your work. Saving time and electricity, reducing airborne toxin and work area noise that can lead many health problems. Suitable for Most Medium Duty Workloads. Etoolcity automatic vacuum switch has a starting threshold of approximately 0.25 amps30watts at 120V and 60watts at 220V, perfectly suited for medium-sized work loads such as most Miter Saws, Table Saws, Power Sanders and Routers, and extend the life of your vacuum. More Safety. Adopting high-cost, UL-certified American Standard 14AWG power cord which allowable passage with a large current that more than 30A, the Etoolcity Automatic Vacuum Switch can work stably within 3600W. The switch's shell has PCABS V0 grade flame retardant material, it is more reliable and safe to protect work. Two Installation Methods. You can use screws to fix the power module part, or use strong nano-markless hook sticker to attach directly to the wall. Both ways are very strong.

No Overload Any More - If the tool motor connected to the '' port exceeds 27.5W, the vacuum connected to the '' port will automatically delay 0.5s to turn on, which helps prevent circuit overloaded by large current if tool and vacuum power-on at the same time. NOTE The current sum of the tools used on III should not exceed 15 amps. Pls check if it fits before buying.. 0.5s Auto Delay Control for the Vacuum On - The shorter the delay, the faster your vacuum will work, the cleaner your home will be. Automatic delays 0.5s to turn on the vacuum when you start your tool, which is more fast than other switches in the market. Why not make your home a little cleaner. 5s Auto Delay Control for Vacuum OFF - When you turn off your power tools, delays 5s to turn off the vacuum. After careful calculation and investigation, we find that 5S is enough to completely clean up your Inlet tube when you complete your work. So just saving your time,energy and electricity..
