The Barksdale D3H-Aa2Ss Actuated Switch is designed for pressure or vacuum sensing in industrial control systems, triggering a circuit when a specified pressure or vacuum threshold is reached. It carries a 250 VAC electrical rating and can switch up to 4 A, making it suitable for interfacing with standard control relays and safety interlocks in machinery and process equipment. As part of Barksdale's D-series family of pressure switches, the D3H-Aa2Ss supports both pressure and vacuum actuation in rugged, field-deployed environments where precise threshold switching is required.
