You should be able to rewire what you have. If you have three wire brake siwtches, then they are double-poled. Each switch has a normally open contact, and a normally closed contact - with a common return for both.
So, you need to find the contacts that are open when the brake handle is at rest, but close when you pull it in.
FInd a wiring diagram. It might be as simple as unplugging and re-plugging some wires. Possibly might have to change the connector gender on one or two, etc.
