These are the ones I used;

Albeit on a router, they work well and are very repeatable. Because they are 3 wire NPN you can power them from a 24v supply but still connect the output to your 5v bob input where they either leave it open (high) or short it to ground (low).
The drawing here shows how they are connected; (bottom left corner of drawing)

I only have a 5 volt supply will this work?
