ACE Replacement PC Boards allow you to give your existing touchpads a new lease on life. If the plastic parts in your machine are still good, simply disassemble, give all parts a good scrub with detergent and re-assemble with new boards. It's simple and you'll be amazed at the difference of how new tactile switches feel compared to the old worn switches.
