This board is a complete redesign of the opto PCB used on the dozer blade assembly of the Road Show pinball machine.

This board has two optical switches that help determine the position of the dozer blade in front of Ted's head on the playfield. The motor shaft on the assembly has a plastic disc with one blade which passes through the two optical switches. The game knows when the blade is up or down depending on which switch is interrupted.

Wide-slot optical switches eliminates any possibility of rubbing of the plastic interrupter. Larger traces and pads for better reliability and longevity.
