I want to hook up a relay to control my spindle. Just on/off.
I am assuming a 5V relay, what kind of amperage rating do I need for the contacts? I use a dremel tool for the spindle, but I dont know how much current it draws. The biggest I can find is 3A, all the rest are 500mA or less.
Has anyone done this? Any suggestions on how to hook it up?
