7.16 Lens shift safety switch

Introduction
For some projector lens types and using the maximum lens shift range, it could be possible that the lens edge hits the engine. To
make sure that the engine will not be damaged, a lens shift safety switch prevents the lens from shifting any further in the actual
direction when it is touched by the lens edge. Only shifting the lens in the other direction is possible at that point.
