💡 What is an air compressor pressure switch and why replace it with a compatible unit?

The pressure switch acts as the brain of the compressor, telling it when to start and stop to hold the right air pressure.

• The switch helps prevent overpressure and short cycling, keeping airflow steady
• Using a compatible upgrade ensures correct wiring and PSI range for your model
• Replacing worn switches reduces motor strain and extends compressor life
