Swapping Rubber-Membrane for Microswitches? Answered
Is it possible to convert a button from using a rubber contact to using a microswitch? The intent I have in mind is to take the buttons on a GBA and make them more like those on the SP/DSi/3DS, but the idea could be applied to any instance of squishy rubber-contacts.
My best guess of how to go about this would be to trace the positive and negative leads into the switch on the circuitboard, then to somehow break that connection and reroute them into the microswitch by soldering wires to them. I need to go double-check the leads are available on the particular board I'm working with, and I wanted to test the general theory using a cheaper board like a TV remote.
