Ashcroft B424P Pressure Switch

Ashcroft B424P Pressure Switch is a pressure-triggered control device that actuates at 30 psi to start or stop connected equipment, making it a compact, dependable choice for hydraulic, pneumatic, and liquid-service applications where precise pressure thresholds govern operation. Part of Ashcroft’s B-Series general-purpose line, the B424P is designed for standard control wiring and is rated for 125/250/480 VAC operation, aligning with common industrial power supplies. In typical installations, the switch is capable of handling general-purpose loads up to 15 A at these voltages, allowing direct control of pumps and compressors without external relays in many settings. The B-Series can be ordered with UL/CSA-listed switch elements and supports multiple voltage configurations, giving integrators flexibility to match control panels and instrumentation cabinets. With its 30 psi setpoint and robust electrical ratings, the B424P provides a reliable threshold for safeguarding equipment and maintaining process consistency in process lines, water-handling systems, and industrial automation where pressure-driven control is essential.
