As I tried to describe how the solenoid functions within this complex sychronized mechanism of actually three mechanisms but in a different thread:

Dark exposure problems on K-30 or K-50? Discussion Thread - Page 20 -

Also there is a link to the original US patent and I added a photo just quickly taken to show how these 2 toothed wheels next to the solenoid act
with this optical sensor. With AF and A lenses they work together with the solenoid, but with manual lenses in M-mode the solenoid is not at all in action!
