  • Ashcroft DDS Industrial Pressure Switch

    Ashcroft® series DDS differential pressure switches are designed to sense low differential pressures between high pressure sources. The design is symmetric such that both the high or low pressure sides of the element can withstand the maximum pressure with the opposite side at atmospheric pressure. The rugged cast aluminum housing incorporates a “frictionless” switching mechanism, and can be specified as watertight or explosion proof. The housing is large enough to accommodate up to one full size SPDT or one DPDT electric switch.
