The HD2T designation signals two switching points within a single unit, enabling automatic on\/off control of equipment in response to rising or falling pressure or vacuum. The GH variant denotes a hermetically sealed construction with gold contacts, a combination commonly rated around 1 A at 125 VAC for the contact set (note: GH configurations are not available on some vacuum models), and the 3SS suffix indicates the diaphragm\/ wetted‑parts configuration used in this family. These characteristics position the HD2T-GH3SS for applications such as HVAC control loops, pneumatic process instrumentation, safety interlocks, and other systems requiring repeatable, low‑current switching tied to precise pressure or vacuum changes. The model is part of Barksdale's longstanding mechanical pressure\/switch lineup, which emphasizes diaphragm‑based sensing, robust stainless‑steel wetted parts in suitable variants, and factory or field adjustments to suit specific service ranges. \u003c\/p\u003e\u003c\/div\u003e","brand":"Barksdale","offers":[{"title":"New","offer_id":46267097874666,"sku":null,"price":432.0,"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-hd2t-gh3ss-pressure-or-vacuum-actuated-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
