{"product_id":"120-009","title":"120-009","description":"This high-performance HVAC High Pressure Switch is a critical safety component designed to protect central air conditioning and heat pump systems from damage caused by excessive internal pressure. Operating as a 'Normally Closed' (NC) sensor, this switch monitors the refrigerant line and automatically opens to interrupt the electrical circuit if pressure reaches 650 PSIG, effectively shutting down the compressor to prevent mechanical failure. Once the system pressure cools and drops to a safe level of 450 PSIG, the switch resets, allowing for normal operation to resume. Durable and reliable, this air pressure proving switch is an essential replacement part for maintaining the longevity and efficiency of residential and commercial cooling equipment. It ensures your HVAC system remains within safe operating parameters, preventing costly repairs and downtime.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Commonly used in central air conditioning units and heat pump systems to provide high-pressure compressor protection.\u003cbr\u003e\nSpecifications: Cut-out Pressure: 650 PSIG; Cut-in (Reset) Pressure: 450 PSIG; Switch Configuration: Normally Closed (NC); Function: Air Pressure Proving\/Safety Limit","brand":"BCFurnace","offers":[{"title":"YORK\/ETC HIGH PRESSURE SWITCH 650-450 PSIG NORMALLY CLOSED \/ 120-009","offer_id":50216732918045,"sku":null,"price":178.68,"currency_code":"CAD","in_stock":true},{"title":"YORK\/ETC HIGH PRESSURE SWITCH 650-450 PSIG NORMALLY CLOSED \/ S1-02546848000","offer_id":50216732950813,"sku":null,"price":178.68,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/d43944938f5d470a833923e6f71669dd.webp?v=1773967973","url":"https:\/\/bcfurnace.myshopify.com\/products\/120-009","provider":"BCFurnace","version":"1.0","type":"link"}
