Torch Switch Interface Prototype

Have a strange interfacing I have to do between two different manufacturers of two very different machines. Designed a small breakout board for an opto-isolator to provide signaling while maintaining isolation between the two systems. Boards were made to spec. I do like how more an more manufacturers are putting a visual representation of what was uploaded so you can see what the final product will look like. For super dense multi-layer boards its not useful, but for us makers who only make two sided boards its very easy to see our screwups/poorly formatted labeling. Prototypes worked well, so will be ordering a bigger chunk of them to deploy.
