i-Socket is the ONLY intelligent switch that can automatically control the in-rush of current on startup to eliminate circuit overload with a 7 second delay off. Preferred by Framing, Flooring and Cabinet Contractors, it’s actuation threshold of about 0.7 amps (85 watts at 120V) makes it perfectly suited for most Mitre Saws, Table Saws, Power Sanders and Routers and extends the life of your vacuum system.
