Its four-port manifold and built-in unloader valve vent the pump head when the cutout pressure is reached, enabling a smoother restart and reducing motor wear during cycling. The unit is specified for a 150\/120 psi cut-in\/cut-out operating range, aligning with Campbell Hausfeld service specifications for this model and matching the needs of standard open-frame and compact compressors that rely on a CW211300AV switch. Designed for easy installation in a 90-degree configuration, it supports common plumbing layouts and wiring arrangements found in Campbell Hausfeld equipment. As a direct replacement part, it helps maintain consistent tank pressure, predictable cycling, and reliable compressor operation across repeated on\/off cycles in residential, shop, and light-industrial applications that use Campbell Hausfeld control components.\u003c\/p\u003e\u003c\/div\u003e","brand":"CAMPBELL","offers":[{"title":"New","offer_id":51677638689070,"sku":null,"price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_333208e0-9bc2-4ff3-92a8-9def33a684f2.jpg?v=1769565789","url":"https:\/\/plgautomation.com\/products\/campbell-hausfeld-cw211300av-pressure-switch-four-port","provider":"PLG Automation ","version":"1.0","type":"link"}
