Its primary function is to monitor system pressure and automatically switch the compressor motor on or off to maintain pressure within a preset band. This specific model offers a switching range of 0.5 to 0.8 Megapascals (equivalent to 5-8 BAR or 90-120 PSI), providing a adjustable cut-in and cut-out point. It is offered in two distinct electrical configurations: one rated for 220V systems and another for 380V systems, allowing you to select the correct variant for your workshop or industrial setup. The switch is presented in a European-style assembly, comes with a normally closed contact method, and is designed for integration into a system using standard fittings.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Air compressor pressure switch with gauge, 12MM connector, and adjustment dial for 0.5-0.8 MPA range.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/310\/2025-09-30\/original-image\/543b774b-1a21-46d8-9a49-575ca7f447f8.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis pressure switch is built around its core function of reliable pressure sensing and electrical switching. The construction centres on the pressure sensing mechanism and the electrical contacts rated for the high current draw of a compressor motor.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe switch housing contains the pressure-sensing diaphragm and the electrical switching mechanism. It features a normally closed (NC) contact configuration, meaning the circuit is complete when the system is at rest and opens when the target pressure is reached to stop the motor. The unit is marked with its maximum ratings: a maximum voltage of 240V, a maximum current of 20 Amps, a maximum pressure of 12 BAR, and a maximum PSI of 175. These ratings define the operational limits of the component. The stated lifespan of the switching mechanism is 80,000 cycles, indicating its design for repeated use.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe pressure switch itself is a compact unit designed for mounting on or near the compressor tank. For connection to your air system, it is equipped with a 12MM connector, which is also specified as a 1\/4 inch thread, a common size for compressor accessories. It also includes a 6MM exhaust port, likely for an unloader valve or bleed function, and a separate pressure relief port with a 9.5MM outer diameter. The product is supplied in a small cardboard box measuring 185mm in length, 100mm in width, and 110mm in height. The net weight of the switch assembly is 635 grams, with the total packaged weight coming to 720 grams.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Air compressor pressure switch with gauge, 12MM connector, and adjustment dial for 0.5-0.8 MPA range.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/310\/2025-09-30\/original-image\/70811add-b72b-424e-b4a4-dee48c79088d.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis component is integral to the automatic and safe operation of piston-type air compressors commonly found in garages, workshops, and light industrial settings.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eIn professional environments like automotive repair shops, carpentry workshops, or manufacturing cells, consistent air pressure is crucial for powering tools like impact wrenches, nail guns, and spray painters. This pressure switch maintains the air receiver tank within the set 5-8 KG\/cm² (0.5-0.8 MPA) range, ensuring tools receive adequate pressure without causing the compressor to run continuously. The 20A maximum current rating and choice of 220V or 380V variants allow it to be matched to the electrical supply of industrial-grade compressors.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor the home DIY enthusiast with a workshop compressor, this switch performs the same vital function. It automates the compressor, filling the tank to the upper set pressure and then shutting off, only restarting when pressure falls to the lower threshold. This protects the compressor motor from overheating due to constant running and manages energy use. The clear pressure range settings allow users to tailor the system for tasks like inflating tyres, operating a brad nailer, or cleaning with a blower gun.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Air compressor pressure switch with gauge, 12MM connector, and adjustment dial for 0.5-0.8 MPA range.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/310\/2025-09-30\/original-image\/9d2a8771-f652-4bc3-8e37-40f109f7fe58.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe value of this pressure switch lies in its role as a replacement or upgrade part that restores or enhances the automatic functionality of an air compressor system.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eAs a replacement part, this switch can extend the usable life of an existing compressor whose original pressure switch has failed. Its straightforward specification—choosing between 220V and 380V—simplifies the selection process. Once installed and correctly set, the switch requires minimal ongoing maintenance beyond occasional checks for air leaks at its connections. The 80,000-cycle lifespan suggests a robust design suited for long-term use in intermittent duty cycles typical of many compressor applications.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis pressure switch offers a clearly defined specification set. The dual voltage option (220V\/380V) covers a wide range of common compressor models. The inclusion of specific connector sizes (12MM\/1\/4\", 6MM exhaust) and the stated pressure relief port dimension (9.5MM OD) provides the necessary details to assess compatibility with your existing pipework. The defined switching range of 0.5-0.8 MPA is a standard band for many workshop compressors, making it a practical choice for a common repair or build scenario where precise pressure control is needed.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Air compressor pressure switch with gauge, 12MM connector, and adjustment dial for 0.5-0.8 MPA range.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/310\/2025-09-30\/original-image\/b1f9afe8-9abe-48dd-a181-f7debe64d8a1.webp\"\u003e\u003c\/div\u003e","brand":"qxgaba-xf","offers":[{"title":"380V switch","offer_id":57422601486719,"sku":"CJJC147480002BY","price":62.98,"currency_code":"GBP","in_stock":true},{"title":"220V switch","offer_id":57422601519487,"sku":"CJJC147480001AZ","price":57.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/3472\/4735\/files\/b1f9afe8-9abe-48dd-a181-f7debe64d8a1.webp?v=1777358692","url":"https:\/\/qxgaba-xf.myshopify.com\/products\/pressure-switch-for-air-compressors-with-a-0-5-0-8-mpa-switching-range-featuring-a-european-style-assembly-normally-closed-contact-method-and-a-12mm-connector-suitable-for-220v-or-380v-systems-with-a-working-pressure-of-5-8-kg","provider":"DailyVantage","version":"1.0","type":"link"}
