{"product_id":"021-888","title":"021-888","description":"This high-pressure switch is a vital safety component designed for HVAC systems, including central air conditioning units and heat pumps. Functioning as a high-pressure cutout, this Single Pole Single Throw (SPST) switch monitors the refrigerant pressure within the system to prevent compressor damage. When the internal pressure reaches the safety threshold of 650 PSI, the switch opens the electrical circuit, immediately shutting down the equipment to prevent catastrophic failure or leaks. Engineered for durability and precision, this air pressure switch is an essential replacement part for maintaining the longevity and operational safety of high-performance heating and cooling equipment.\u003cbr\u003e\nType: High Pressure Switch \/ Air Proving Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Used in residential and commercial HVAC systems, specifically packaged heat pumps and central air conditioning units to monitor refrigerant line pressure.\u003cbr\u003e\nSpecifications: Configuration: Single Pole Single Throw (SPST); Action: Opens on pressure rise; Cut-out pressure: 650 PSI; Function: High-pressure safety limit.","brand":"BCFurnace","offers":[{"title":"SWITCH; HIGH PRESSURE, SPST, OPEN @ 650 \/ 021-888","offer_id":50216344125725,"sku":null,"price":55.35,"currency_code":"CAD","in_stock":true},{"title":"SWITCH; HIGH PRESSURE, SPST, OPEN @ 650 \/ SWT03542","offer_id":50216344158493,"sku":null,"price":55.35,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/bcfurnace.myshopify.com\/products\/021-888","provider":"BCFurnace","version":"1.0","type":"link"}
