The Ashcroft® A-Series pressure switches are designed for tough industrial and OEM applications requiring a durable, high-quality miniature switch; especially where corrosion resistance or leakage is a concern.

The Ashcroft A-Series is ideal for pressure alarm, shutdown, or control on heavy vehicles, machine tools, electronic equipment, engines, compressors, food and beverage processing equipment, and wherever size is a consideration or equipment is being downsized. Explosion-proof models are available.

Additional information on the Ashcroft A-series of miniature pressure switches:

  • A rugged 316 SS enclosure gives uncompromising protection.
  • Materials of construction have been selected for long life.
  • Precision snap acting micro switches are featured and fully encased to prevent moisture from corroding switch contacts.
  • The switch, depending on range, is either an all welded 316 stainless steel diaphragm sealed piston design or a direct acting piston design sealed with a Buna-N or Viton O-ring.
  • Sealed Switch Element

    We recommend optional sealed switch element for improved reliability.

    The sealed switch provides uncompromising contact protection in harsh or corrosive environments, such as that found in off shore platforms, off-road equipment, outdoor plants and mills, and equipment that is washed down or is subject to frequent temperature changes.

    Ashcroft® supplies highly reliable switches and controls for industrial and process applications. We begin with rock-solid designs, matching the most appropriate technology with the safety and reliability requirements of the applications.

    The materials of construction are specified to Ashcroft’s exacting standards, and product is built to last in the toughest applications.
