David,

take a moment to write down what you want to do with the reverse circuit. I
understand that you want to combine 4 reverse switches into 1 and wondered
what would happen . But the question is: Where did those 4 switches come
from? Are you using a standard circuit repeated 4 times? What circuit?

regards
