The switches themselves do that when they start to wear out. I've had it happen to a number of mice/track balls. Indeed I'll soon be replacing those switches on several track balls and I'll use better switches that have the same dimensions. It may be worth trying to de-dust and de-dust bunny them but it probably isn't the problem.
I bought a mouse with optical switches, which are advertised to never develop this exact problem. I guess I'll have to wait for a couple years to see if the claims check out :P
