Mouse Double-Clicking

Solution 1:

The micro contact switch under the mouse button has a limited number of clicks. Basically its a very small convex metal bubble, that as you press down, it deforms enough to "snap" down and make contact. Releasing the pressure allows the metal to spring back. There is a little bit of plastic insulation that shields the sides of this semi-bubble. So after 10 gzillion clicks, the metal deforms a little and the insulation crudes up. The switch is insignificant in cost, but the effort of finding an acceptable tactile response is major. Mouse technology in the past few years has greatly improved, especially toward longer battery life and making the mice smaller and less klunky. Much more practical to replace it, like you would replace an old pen or pencil.
