We have a catchment system with a 20k tank, and a 3/4hp 3450rpm pump.
The pump's pressure switch fails periodically, every couple of years or longer.
It had a 20 to 40 psi switch.
The 20 to 40 and the 40 to 60 switches looked to be the same except for the settings.
So, I reset the max at 65 psi.
I really like the higher pressure.
Has worked great for years now.
It is a light duty system, only two of us without 50k kids running around.
Because of the higher pressure, the pump does have to work harder, could cause problems.
I have switch replacements sitting on the shelf.
I used to replace it at every failure.
Then, I got lazy.
Now, I simply restart it, haven't even filed the contacts, and still have the same 2 replacements sitting there.
Still get at least a couple of years or more usage between failures.
The worst effect is loosing water pressure when showering after midnight every few years.
Living on a clearing in the jungle at night gives plenty of privacy, don't worry about getting dressed, or worry about rain to restart it.
Edit:
Our switch is mounted on the motor.
The motor has little to no vibration to affect the switch's operation.
Your posts seem to indicate that you're getting vibration that might affect your switch.
If so, give it a long hard look.
It might be an indication of possible failure coming.
The switch melting might indicate a mismatch between the switch and the motor, the switch may not be heavy enough for the motor.

Was a Democrat until gun control became a knee jerk, then a Republican until the crazies took over, back to being a nonpartisan again.
This time, I can no longer participate in the primary.
