    Hi, Im looking for any sort of solution. I have about 30 tactile switches on a circuit. I'd take them off and would like to wire each one to some sort of driver/controller that can be connected to a pc and controlled from it (integrate into visual basic would be a huge bonus but i wont be too fussy).

    If they are normally open you can do both, and have the PC controller across the switch. In the old days we'd use printer interfaces, but those are only good for about 12 switches or so.

    Try googling USB interface to switches.

    Of course, some programing knowledge is going to be required to interface into the USB device. The printer port method was direct memory access, and you could add more printer ports as needed for more switches.
