Part of the design philosophy of the Perfect Switch Harness was to keep all of the important stuff in a friendly environment. That is, no grime and dirt and no vibration. The most vulnerable part of the assembly, besides the switch, is the wiring to the switch. With the Perfect switch Harness a wire to the switch could break off or the switch could fall apart and you'd keep flying. I velcro the regulator to my receiver so it sees the same vibration free environment as the receiver. Of course this isn't as big a concern with electrics.
