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