Ashcroft B420SXCHFSNH07 Industrial Pressure Switch

The Ashcroft B420SXCHFSNH07 industrial pressure switch switches electrical contacts at 15 psi, enabling automatic control of hydraulic or pneumatic equipment whenever process pressure reaches the setpoint. The device is rated for 250 VAC and can handle up to 15 A, making it suitable for switching standard loads in control circuits across a broad range of industrial environments. The NSMP designation is included in this model's string, identifying its specific configuration within the B420 family. The 15 psi switching point denotes the threshold at which the internal contacts change state, providing a precise and repeatable trigger for automation logic, panel controls, and process sequences. This switch is intended for industrial applications where a fixed pressure threshold must initiate or halt operation of downstream equipment such as pumps or compressors. As a member of the B420 series, it supports straightforward integration into control systems requiring reliable, pressure-based actuation. Users should verify compatibility with their control circuitry and ensure the configuration meets system safety and electrical standards.
