How does a Well Water Pressure Switch Work?

A well water pressure switch works by telling your pump when to start and stop. Your pump is what brings water up your well into your water tank (holding tank). When the water tank is full the pressure switch tells the pump to shut off. When the water tank is not full (i.e. you are using water in the home) the pressure switch tells the pump when to start to bring more water to the tank.
