The unit uses a 1\/4-inch NPT pressure connection and is part of Barksdale's D1S\/D2S diaphragm switch family, which provides two independent actuation points for safety and control interlocks. Electrical contacts are rated for up to 3 A at 480 VAC, allowing direct connection to relays or safety interlocks in equipment such as boilers, furnaces, and HVAC air-handling systems. As a dual-setpoint member of the D1S\/D2S lineup, the D2S-A3 delivers reliable, repeatable performance in industrial environments where low-pressure sensing is critical.\u003c\/p\u003e\u003c\/div\u003e","brand":"Barksdale","offers":[{"title":"New","offer_id":46267112227050,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-073.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/barksdale-d2s-a3-pressure-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
