{"product_id":"040-133","title":"040-133","description":"This High Pressure Switch (Air Proving Switch) is a critical safety component designed for high-performance HVAC systems, including residential and commercial air conditioning and heat pump units. Functioning as a high-limit cutout, this switch monitors the internal pressure of the system to ensure safe and efficient operation. If pressure levels exceed the manufacturer's safe thresholds, the switch interrupts the electrical circuit to protect the compressor from mechanical strain and prevent potential system failure. Ideal for HVAC repair and maintenance, this durable air pressure switch ensures consistent air proving and provides essential equipment protection. Whether you are troubleshooting a cooling system that won't start or replacing a faulty safety sensor, this high-pressure control is a vital replacement part for maintaining equipment longevity and home comfort.\u003cbr\u003e\nType: Air Pressure Switch \/ High Pressure Cutout\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Used in residential and commercial air conditioners, heat pumps, and furnace systems for pressure monitoring and compressor safety shutdown.\u003cbr\u003e\nSpecifications: High-limit safety cutout functionality, air proving capability, durable housing for HVAC environments, calibrated for high-pressure system protection.","brand":"BCFurnace","offers":[{"title":"High Pressure Switch, 448-327# \/ 040-133","offer_id":50215338836253,"sku":null,"price":81.55,"currency_code":"CAD","in_stock":true},{"title":"High Pressure Switch, 448-327# \/ HK02ZA439","offer_id":50215338869021,"sku":null,"price":81.55,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/1af2a0b2c6af4bf18839da1513443905.webp?v=1773958040","url":"https:\/\/bcfurnace.myshopify.com\/products\/040-133","provider":"BCFurnace","version":"1.0","type":"link"}
