   It sounds like the little pipe/hole feeding the PS assembly is plugged.

   Remove the switch, ream out the 1/8"? pipe with a piece of wire and flush it out by turning on power for a min or two.

   Or replace it for $.50.

   Also, most pressure switches have grossly undersized contacts.  Had exactly the same problem you have experienced years ago*.  Fix was to put in a 24 Vac transformer and sent that to the pressure switch and then to a motor contactor -- so the pressure switch only switched a low voltage/low current, then fed the 24 Vac from the prssure switch to  a big wonkin' 5 HP motor contactor. No further problems, last 18 years. 

   *root cause and why the manual worked for me - when you do the manual switch, there is a higher contact force and it breaks thru arc damaged contact oxidation.

   My mom has a pressure switch on her pump that must be held on manually until the system has achieved a minimum pressure.  This is a safety feature to keep the pump from running endlessly if for some reason it is incapable of pumping water/building pressure. 

   A common occurence is for the power to go out.  The water in the pressure tank is used up.  The power comes back on but the pump does not.  To get the pump to work again you go out, hold the lever manually until it builds up five or ten psi and then you can release it and everything is fine until the next power outage.

   Don't know if this is the case in your situation but it is worth a shot.
