{"product_id":"021-879","title":"021-879","description":"This High Pressure Control Switch is an essential safety component designed for HVAC and refrigeration systems. Engineered to protect your cooling equipment from excessive internal pressure, this fan-disc style high-limit switch ensures reliable system performance and prevents compressor damage. The switch is calibrated to automatically open the electrical circuit when the system pressure reaches a high-limit threshold of 405 PSI, halting operation to maintain safety. Once the pressure levels return to a safer range of 300 PSI, the switch closes, allowing the system to resume normal operation. This durable pressure limit control is a common replacement part for maintaining the efficiency and longevity of residential and commercial air conditioning and heating units.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nApplication: Commonly used in air conditioning units, heat pumps, and refrigeration systems as a high-pressure safety cutout and compressor protection device.\u003cbr\u003e\nSpecifications: Opening Pressure: 405 PSI; Closing Pressure: 300 PSI; Type: Automatic Reset High Pressure Switch","brand":"BCFurnace","offers":[{"title":"High Pressure Control Switch, Opens 405, Close 300 \/ 021-879","offer_id":50216342618397,"sku":null,"price":37.18,"currency_code":"CAD","in_stock":true},{"title":"High Pressure Control Switch, Opens 405, Close 300 \/ SWT01719","offer_id":50216342651165,"sku":null,"price":37.18,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/e99d5a679c824e13896d09e208b09eb7.webp?v=1773967895","url":"https:\/\/bcfurnace.myshopify.com\/products\/021-879","provider":"BCFurnace","version":"1.0","type":"link"}
