I have a (high velocity air) dual AC brush motor pet hair dryer (details). (There is no heating element.) It's rated at 120 Volts 18.5 Amps. It has a rotary knob (listed on the parts page as a "Variable Speed Switch and Circuit Board") that clicks on & off and then rotates to set the motors' speed. It's a bit of a pain to click it on and then find the desired speed setting each time. Plus it's wall mounted and a bit hard to reach. I'd like to plug it into a switched wall outlet and use that to turn it on and off, and leave the speed setting at the typical use level (about 90%). It that safe to do? Or can doing that cause damage to the motors or electronics?
[edit/update] It's currently on a 20 amp circuit and I would have an electrician install a properly rated wall switch for this.
