I just "rebuilt" my slap-stick shifter, so I know how it works. There's a series of very significant rachet "teeth" on a plate attached to the shifter and a spring-loaded bar that crosses the teeth. As you "slap" it from 1-2 the spring-loaded bar engages the next "tooth" and prevents you from going all the way into 3 or D. As you let off the pressure on the shifter the cross-bar drops into a different "detent" and then it's ready for the next shift. Reasonably simple, actually, and works pretty well if you keep the moving parts clean and lubed properly.
