"Following that same thread, Roger Moment, in a series of articles a
few years ago recommended that if you are starting a newly rebuilt
engine or are otherwise going to run the starter motor under load
extensively, that you take the switch out of the circuit by connecting
both of the cables that run to the switch onto the same post or
otherwise complete the connection. Then after the car starts with no
more than normal effort you can put the switch back into the circuit."
---------------------------------------------------------------------
I cannot think of a better commentary than this upon the switch's
reliability.
