How Pressure Switches Work?
Pressure switches are devices used to monitor and control pressure levels within a system. They work by sensing the pressure of a fluid (liquid or gas) and activating or deactivating an electrical circuit based on preset pressure thresholds. Here's a basic overview of how they function:

1. Sensing Element: The core component is usually a diaphragm, piston, or bellows that responds to pressure changes. As pressure increases or decreases, the sensing element moves accordingly.

2. Mechanical or Electronic Action:
In mechanical pressure switches, movement of the sensing element triggers a mechanical contact, opening or closing an electrical circuit.
In electronic pressure switches, sensors convert pressure into an electronic signal, which then activates a relay or circuit.

3. Setpoint Adjustment: Pressure switches are adjustable so that they activate at specific pressure levels—either on rising pressure (high-pressure switch) or falling pressure (low-pressure switch).

4. Activation/Deactivation: When the pressure reaches the setpoint, the switch's contacts change state; either closing to turn on a device (like a pump or compressor) or opening to turn it off.

5. Applications: They are widely used in HVAC systems, water pumps, industrial machinery, and safety systems to ensure pressure stays within safe limits.
