    Yeah, google wasn't very helpful. It kind of looks like a triac, which would fit with the machine control aspect, but the symbol looks a little messed up. Can you show us more of the schematic?

    My best guess would be an SCR. We could probably tell you for sure if we seen how it is placed in the schematic.

    Yeah, a badly drawn SCR or triac. Schnitzer, do you have a real example of the physical device? If so, how many connections does it have? How big is it? Can you do a little testing on it to see if it acts like an SCR? If so, then somebody just botched the schematic symbol, and the top output line should be coaxial with the bottom anode input line. Check out what a real SCR symbol looks like, and test the device if you can.
