Brake light switch

My 1931 Tudor has hydraulic brakes. They were on it when I bought it. I have rewired tail lights and turn signals. My master cylinder has 2 brake light switches, one in front and one in back of master cylinder. Does it make a difference to which one I use?
 
Use them both. Wire them in parallel.

That way the first one to close will turn on the brake lights. If one fails, the other will handle it.
