I have a sectional couch with electrical recline. Each section reclines with a separate button. I would like to add a toggle switch that would allow the recline buttons to make all sections recline at the same time. Each section has a 29V DC power supply going to a motor and then push buttons to recline forward/backwards.

I've simplified the problem for now to 2 sections and one recline direction as I think I can generalize it from there.

I have a software background so I started by using boolean logic to understand the solution, which gave me:

Q_A = A + BT

Q_B = B + AT

A = switch on section A

B = switch on section B

T = toggle between individual recline and combined recline

Q_A = output to motor A

Q_B = output to motor B

So my first instinct was to just build that with relays:

So I have two questions:

1. Is there a better way to solve this problem?
2. If relays are a good approach, is there a better way than the circuit above?
