What is the role of a pressure switch in an air compressor?

• A. To lubricate internal components
• B. To regulate the compressor’s operation by managing power supply
• C. To detect ambient temperature
• D. To filter incoming air

Answer: (B)

The role of a pressure switch in an air compressor is to regulate the compressor’s operation by managing the power supply based on the pressure level within the system. When the pressure reaches a pre-set limit, the pressure switch signals the compressor to turn off, preventing over-pressurization. Conversely, when the pressure drops below a certain threshold, the switch activates the power supply to restart the compressor, ensuring consistent pressure and optimal performance. This regulatory function is crucial for maintaining safety and efficiency in compressor operations. By automating the start and stop cycles based on real-time pressure readings, the pressure switch also helps conserve energy and prolongs the lifespan of the compressor by avoiding unnecessary running times or excessive wear on the internal components.
