Typical well water system pressures are (On/Off): 20/40, 30/50, 40/60. These are the most common presets for pressure switches. A lot depends on the recovery rate of your well and the condition and capacity of your pump.
Try the 40/60 settings but, make sure that the pressure in the air side of your tank is 2 pounds less than the low setting. Measure it with a tire gauge with the pump shut off completely and all pressure bled off the water side of the system. After starting the pump again, if the system cannot reach 60 psi in a reasonable amount of time, say two minutes, then your pump isn't up to the task of a 60psi system. Usually 1/2 hp shallow well pumps are 30/50 systems.
If after doing all this your water pressure is still bad, you might check any filters on the system and change those, clean all strainers and aerators, especially the tiny pin hole jets in the white nylon part of the aerator, not just the screens. I had a customer complain about a pump I sold him. I went to the house and of course he swore all was clear in the aerators as I was taking it apart. I took a pin and cleaned the pinholes of polyethylene shards from his installation work. Great pressure and flow after that!
