The KMC Controls CCE-1001 Pneumatic Electric Switch is a control device that converts pneumatic signals into electrical switching action for HVAC systems. It operates by sensing air pressure changes and activating electrical contacts to control connected equipment. Commonly used in building automation systems, air handlers, and ventilation units, it enables coordinated control between pneumatic and electric components. This switch improves system integration, enhances operational reliability, and supports precise control of heating and cooling functions while contributing to energy efficiency and reduced maintenance requirements.
