It regulates pump pressure by opening and closing the electrical circuit to the pump, while the built-in unloader valve diverts flow when the spray gun is released to prevent overpressure and enable a smooth shutdown. A manual lever provides direct control for priming, testing, or temporary bypassing of the trigger during service. This part carries the 034-0137 model number and is intended for Coleman Black Max units that require this switch, helping maintain unloading performance and reliable operation in compatible machines.\u003c\/p\u003e\u003c\/div\u003e","brand":"COLEMAN","offers":[{"title":"New","offer_id":51678315643182,"sku":null,"price":117.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_36426531-829f-4e84-b849-b33c36062b87.jpg?v=1769574515","url":"https:\/\/plgautomation.com\/products\/coleman-034-0137-pressure-switch-with-unloader-valve-and-lever","provider":"PLG Automation ","version":"1.0","type":"link"}
