I was not able to set the two end switches and movable rod to work right on my Engel periscope retract mechanism, until I made this small improvement with washer and two shortened springs.
The problem was that first switch stopped motor movement before was the second switch activated so the reversed movement of the motor was not possible. Now, the spring push the rod to the desired position to hit the second switch even after the first switch stop the motor (and the rod) movement. So the reverse movement of the motor (and periscopes) is now possible.
