Designed to automate dust collection, the iVac Switch senses when a connected power tool is turned on and automatically activates the associated dust collector or vacuum system. When the tool is switched off, the iVac keeps the vacuum running for approximately six additional seconds to help clear remaining airborne dust and debris. The switch features three operating modes—Auto, Off and On—and includes a short turn-on delay to help prevent the startup surge of the power tool and vacuum from occurring at the same time. This can help reduce the chance of tripping a circuit breaker during startup. For higher combined loads, the iVac Switch includes two input power cords so the tool and vacuum can operate from two separately protected 15 Amp AC circuits. Each power cord is individually protected by a 15 Amp circuit breaker. Its compact, lightweight design can also be wall mounted for convenient installation. Features Automatically turns a dust collector or vacuum on when the connected power tool starts Automatically turns the dust collection system off after the tool stops Approximately 6-second turn-off delay helps clear remaining airborne debris Adjustable turn-on delay from 0.5 to 2.0 seconds Helps prevent simultaneous startup surges from the tool and vacuum Three operating modes: Auto, Off and On Designed for continuous operation Compatible with a wide range of dust-producing power tools Compact and lightweight design Can be wall mounted Two input power cords allow operation from two separately protected AC circuits Each power cord is protected by a 15 Amp circuit breaker ETL safety approval Specifications Product: iVac Switch Operating Modes: Auto / Off / On AC Circuit Requirement: One or two 15 Amp AC circuits Maximum Tool Current: 12 Amps Tool Detection Range in Auto Mode: 0.3-12 Amps Turn-On Delay: 0.5-2.0 Seconds Turn-Off Delay: Approximately 6 Seconds Input Power Cords: 2 Circuit Protection: 15 Amp circuit breaker on each power cord Mounting: Wall mountable Safety Approval: ETL FAQ What does the iVac Switch do?It automatically turns a connected dust collector or vacuum on when your power tool starts and turns it off after the tool stops. How long does the vacuum keep running after the tool is turned off?The iVac Switch provides an approximately 6-second turn-off delay to help clear remaining dust and debris. Why is there a turn-on delay?The short delay helps prevent the power tool and vacuum from creating startup surges at the same time, which can reduce the chance of tripping the AC circuit breaker. What are the three operating modes?The iVac Switch includes Auto, Off and On modes. What is the maximum power tool current?The connected power tool should not exceed 12 Amps. Can it use two separate electrical circuits?Yes. The two input power cords allow the tool and vacuum to operate from two separately protected 15 Amp AC circuits when required. Does each power cord have circuit protection?Yes. Each power cord is individually protected by a 15 Amp circuit breaker. Can the iVac Switch be wall mounted?Yes. Its compact design allows for wall mounting. Is the iVac Switch safety approved?Yes. The supplied product information states that it has ETL safety approval.
