York S1-PSW-610 610# M/R High Pressure Switch

Description

The York S1-PSW-610 is a 610 lb/in² manual reset (M/R) high pressure switch engineered to protect refrigeration and HVAC systems from potentially damaging high-pressure conditions. When system pressure exceeds the factory-set threshold, the switch opens the circuit and requires a manual reset before the system can resume operation — ensuring a technician inspects the root cause before restart.

Key Features

• 610 PSI set point for high-pressure cutout protection
• Manual reset (M/R) design prevents automatic restart after a high-pressure trip
• Direct York OEM replacement part (SKU: S1-PSW-610)
• Designed for use in refrigerant circuits requiring reliable high-side pressure monitoring
• Helps safeguard compressors and system components from pressure-related damage

Applications

• York residential and commercial HVAC systems
• Refrigeration systems requiring high-pressure safety cutout
• OEM replacement in York-branded equipment

Why Manual Reset?

A manual reset high pressure switch is a critical safety device. Unlike auto-reset switches, the M/R design locks out the system after a high-pressure event, requiring a qualified technician to diagnose and resolve the underlying cause — such as a refrigerant overcharge, blocked condenser, or non-condensable gases — before the equipment is returned to service. This reduces the risk of repeated compressor damage and potential system failure.
