woodartist said:The tow vehicle doesn't supply the power for the brakes and break away switch???? Requires a battery? Don't understand that.
woodartist said:Thanks..kind of makes sense. Seems like an odd design that requires power to engage a safety device. I'm not disputing what you say...just that the concept is something I don't understand. I would think the brakes would require power to release and if the power went away, or the switch was pulled, then the brakes would engage. Better minds have apparently thought this out.......
Think of it this way: Assume your car or tow vehicle requires that you step on the brake pedal to keep the brakes OFF. That requires constant energy while driving. You could never relax your 'brake' leg. Same with a towed vehicle, plus now you have to rely on the total electrical system to be intact to keep the brakes from coming on. That means fuses never blow, connectors always maintain good contact, switches never fail, wires never get damaged by stones or mice, etc. or else your trailer brakes could come on at any time. There's also the engineering aspect of how to modulate the brakes by introducing the proportionally correct resistance into the circuit.Hate to have a safety device that needs power

Otherwise, I guess the driver would need to activate it using some type of remote-control button, etc.
