Automatic Vacuum Switch for Power Tools, Etoolcity Unique Current Sensing Technology to Delay Vacuum On to Prevent Circuit Overload, Eliminating Circuit Breaker Tripping

Product Information

About this item

• 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
