Does the joystick come with a pigtail of some sort?
I'm pretty sure the switches are just switches - unless they are wheel type where you can scroll or set a level. On-Off are usually just a switch even if there are electronics present to convert the signal to something digital like a serial interface.
You wouldn't happen to have a pic?
This is my area of expertise and I know for a fact that finding switches and connectors is the biggest PITA there is when it comes to electronic components.
