Works great, all of the tolerances fit my gaggia classic and switches from amazon. The switches I purchased worked as a drop in replacement for the existing ones, same pinout minus the pins not connected to anything. (Also the brew thermostat light doesn't work). Here are the ones I purchased for anyone doing this in the future:
