What makes it a problem to orders switches yourself? Mechanical switches are not a rocket science, and any electromechanical OEM would've been happy to work on them with such premiums. I myself been thinking of ordering double action switches, so you don't need debouncing them. I even contemplated adding some ultra low power latches to be overmolded inside, so you get a single output out of the box.
