>>>No.   Your starter is working fine.   The most obvious suggestion is to 
check all your connections--at the battery, starter solenoid, and the 
starter itself.

Assuming they are all good, the problem is almost assuredly within your 
disconnect switch.   You don't mention which kind you have? Broadly, there are 
two types.   One has a post that the battery cable clamps to, a clamp to 
attach it to the battery, and a knob (usually green) that you unscrew to 
electrically separate the two halves.   These things are pretty effective, but 
also extremely cheap.   I would imagine (guess) that overtightening can break 
things.

The other kind is a proper switch, with two posts (one for the cable in, 
another for a cable out) and a keyed switch in between.   These seem to be 
more robust.

As an experiment, remove the switch from your system and evaluate 
performance.   It's likely that things will function just perfectly.   At that point 
you get to decide whether you want to service the switch (could there be a 
buildup of corrosion), replace it, or just do away with it entirely.

FWIW I have key-type switches on two cars, and a knob-type switch on a 
third one--all of them have worked great for years, although the knob-style 
switch is rarely disconnected so it hasn't had a chance to wear out yet.

Let us know what you find out!
