My first post here so treat me well 
I trying to create a logic circuit that will turn a normally closed circuit to an open circuit.
The current switching state is below left and how I require to have it is on the right:
Switch control position A/B/C
A OFF - 1 - 0 - 0 - 0 A - 1 - 0 - 0 - 0
B ON - 1 - 1 - 0 - 1 B - 1 - 1 - 0 - 1
C (momentary) - 1 - 0 - 1 - 1 C - 1 - 0 - 1 - 1
D (momentary) - 1 - 1 - 1 - 1 C - 1 - 1 - 0 - 1
R G Y B R G Y B
