My hobbycnc EZ driver kit came with two power switches, one for the AC and one for the DC. I've always wondered about that since I hear it can cause problems with other driver boards. I've never had a problem with it, but I certainly would not flip the switch with the motors running to find out. Same goes with attaching it to the e-stop.
