See which points on the circuit board the switch belongs to and see if there's continuity when you click the switch, I guess.

As far as I can tell, 2SA937-R is a PNP transistor while the 2SC2021 is NPN... that's not going to work.


Ha, I actually expressed concern that the part number wasn't one I'd seen listed. His response: "It's definitely an interchange." Either his eyes are failing or he was desperate to sell $5 worth of transistors. Probably the former, as he's pretty advanced in years.

On the bright side, I'm getting good at soldering/desoldering components that go through the board.
