How do you test a water well pressure switch?

To test a water well pressure switch, first ensure the power supply is turned off for safety. Then, use a multimeter to check the continuity of the switch contacts by measuring resistance across the terminals while manually activating the switch. Additionally, observe the pressure gauge to ensure it reflects the pressure settings of the switch, typically around 30-50 psi for a standard system. If the switch fails to activate or shows inconsistent readings, it may need replacement.
