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 amps(30watts 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 PC+ABS 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

Retaining the proven reliability of our Etoolcity technology, the automatic dust controller switch is the newly Version of the Etoolcity Vacuum Autoswitch-an essential device in workshops and on job sites for more than a decade.

THE NEW ETOOLCITY AUTOSWITCH FEATURES

★New Current Sensing Technology and Actuation Threshold

★Supports a Wide Range of Cutting Tools from Rotary Handheld Devices to Large Shop Saws

★Prevents Circuit Overload with an Auto Turn-On Vacuum Delay

★Runs the Vacuum Only While You’re Using Your Tool So You Save Time and Electricity

★Automatically Delays Vacuum Turn-Off by 7 Seconds to Continue to Clear the Air While the Motor Spins Down

★Helps to Comply with OSHA Requirements for Dust Control

Highlights of the Etoolcity Autoswitch:

▲STARTUP DELAY.Controls in-rush current to help avoid circuit overload

▲AUTO MODE.Turns the vacuum on automatically with the power tool

▲SHUTOFF DELAY.Allows time for the vacuum to clear the hose of debris

Focus On Your Work:

★Save time

★Minimize airborne dust Reduce
