Pressure Switches

Pressure switches are devices that open or close an electrical contact at a specific pressure set point. These switches are used for controlling the operation of pumps, compressors, and other equipment, providing a simple and effective way to maintain or monitor pressure within a system. Pressure switches are vital for safety and process control in various applications, including HVAC, hydraulic systems, and water supply management.

Designed for durability and reliability, pressure switches come in various configurations to suit different pressure ranges, media, and application requirements. They can be mechanical or electronic, with adjustable set points to meet specific operational needs. The use of pressure switches helps prevent equipment damage and ensures efficient operation, contributing to overall system safety and performance.
