What is the function of a pressure switch in a pneumatic system?

The function of a pressure switch in a pneumatic system is to monitor and control pressure levels. This device is designed to detect the pressure of the air in the system and activate or deactivate components based on predetermined pressure settings. When the pressure reaches a certain level, the switch can trigger actions such as activating a compressor or shutting it down to prevent overpressure situations, ensuring that the system operates safely and efficiently.

By continuously monitoring pressure, the pressure switch helps maintain the desired operating conditions, contributing to the reliability and effectiveness of the pneumatic system. It plays a crucial role in automating processes and enhancing system performance by providing feedback to the control circuit about the current pressure status, allowing for appropriate adjustments as needed.
