What is a Pressure Switch?

A pressure switch is a type of switch that is activated by the pressure of the process fluid upon reaching a certain threshold or set point.

Different types of pressure switch symbols are used, with the most commonly used symbols being the ones defined by the IEC and the NFPA (JIC).

What is the Function of a Pressure Switch?

A pressure switch regulates the system's pressure, ensuring that the reservoir level remains stable and safeguarding equipment from damage or running at low efficiency.

What is the Symbol for a Pressure Switch?

A pressure switch electrical symbol is a graphical representation of the component, providing electricians and engineers with an easy means of determining its position within the circuit without the need for a physical inspection.

The electrical contact of a pressure switch is typically NC (Normally Closed), NO (Normally Open), or changeover:

• In an NC contact, the switch arm is in contact with the terminals, meaning that the default position is closed.
• In an NO contact, the switch arm is not connected to one of the terminals, meaning that the default position is opened.
• In a changeover contact, the switch operates between two terminals and can thus be used in either the NC or NO position.
