About this item No Overload Any More - If the tool motor connected to the 'Ⅰ' port exceeds 27.5W, the vacuum connected to the 'Ⅱ' 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 "I"+"II" 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.
