Rather than switching the direction, it is shorting across the terminals. Sorry for the misunderstanding.

Well our system is a little bit different. We have a transmission as described that does not shift. That transmission pulls back the winch to any desired start point and we have a brake system that holds the catapult in position while the winch unwinds to the desired hard stop length. Then the lock that I described in the previous post comes in. We did this to eliminate the need for a two speed transmission.
