Pressure switch for water filtration system
By sensing a change in system pressure, a pressure switch is commonly used to turn a water pump on and off. When a specified pressure point is achieved, a pressure switch detects it and opens or closes an electrical switching element. In most cases, a pressure switch may be adjusted to the desired set point of operation. They are used to respond to fluid pressure and are also known as pressure sensors.
How pressure switches/pressure sensors work
All of the work is done by water pressure in pressure switches. The water from the well provides the pressure shift that triggers the switch. The pressure rises via the diaphragm and is applied to a piston and spring, which opens or shuts the contacts.
