My mouse left button is getting real flakey. I took the whole thing

Have any of you ever found a way to repair these switches?

Yea, I know computer mice are cheap, but I need a PS/2 connector and
want a ball mouse. I dont like the infared mice, and can not use a USB
mouse on my Windows 98 computer.

So, I have to order this on ebay since all the ones in the stores are
USB and infared these days.

So, until I can get one from ebay, is there any temporary fix? (The
other mouse functions work fine).

Are you sure it doesn't have a broken solder joint on the switch? Years of clicking could cause cracking.
