Part of a hackaday.com to make a game controller for people with physical disabilities http://wp.me/pk3lN-pNO You can also contribute at www.thecontrollerproject.com This case uses a simple lever design to reduce the force necessary to push a 6mm momentary switch from 60 grams down to about 15grams of pressure. there are two versions here. One that snaps together and one that is more rugged that will need to be drilled. I use a piece of paperclip as a hinge on the more rugged one.
