Could the mount be just slightly bent and loose enough that it pulls 
away from the body in degrees which varies with the weight of the lens 
attached?
It is assumed there is no screw hole on the adaptall sitting over the 
spot switch and that the switch is indeed in good working order and not 
clipped by said mount.  Unusual.

There's also a problem not related to impact.  The plastic frame that 
the top cover spot switch is mounted to is held tight against the top 
cover be 3 screws going into plastic posts.  It is quite common for the 
plastic posts to crack, plastic frame rises and spot button will no 
longer be able to make contact when it is depressed.  If this were the 
case it would most likely malfunction with all lenses.
