Adjustable height micro switch

The micro switch lever has a roller on it that rolls up onto the plastic bushing (“B-1 bushing”). Power stops going to the motor when the lever is lifted. The micro switch is mounted to a bracket that can be moved to stop the platform at the desired height.

To adjust the location of the bracket use a 3/32″ hex wrench to loose the two set screws on the bracket that slides on the rod.
