How do you setup switches on a PCB that work from outside a case?
I am using the switches that mount to the PCB. I would like to activate them from outside the case. Indoor use, small is good.
Is there a right/easy way to do this or will it work to drill a hole and stuff a matching plastic rod into it, maybe a rod in a tube epoxied to the case. Mushroom the underside of the rod to keep it from falling out. The space between the case and the top of the switch will be 2 or 3 mm. I have some adjustment here. Maybe someone make an button insert that pops into a hole to push the button?
The case is a Hamond with a wall thickness of 2mm.
The switches are E-Series Tactial Switch 6.4X5.0MM 130G switches.

How often will you need to press the buttons? If it's rarely or infrequently, just drill holes and poke something through. Glue a small piece of tubing (guts out of an empty ballpoint pen) to the button.
How about the little plastic pieces that explode out of a remote or calculator when you pry them open? Don't know how you would drill a rectangular hole, maybe a dremel and a small router type bit.
Since your PCB is so close to the surface of the enclosure, you could drill a hole directly over each switch and drop in a plastic ball (Wal-Mart and craft stores such as Hobby Lobby have all sorts of beads and balls in their crafts/scrapbooking sections). Cover with a nice, thick polyethelyne strip using double-sided tape. The accessory bags that came with Hewlett-Packard test equipment was wonderful stuff for such applications.
