it is highly recommended to only use this as a direct replacement for the York S1-025-26392-005 to ensure the temperature setpoints and reset logic match the manufacturer's safety sequence

The bi-metal sensing element provides reliable continuity under normal conditions and opens the circuit instantly upon reaching the high-temperature threshold

they should be sourced separately to ensure a complete pneumatic seal

ensure proper routing to manage the 25-inch lead length

MARS 43335 Pressure Switch and Gibson that utilize theThe MARS 43335 Pressure Switch is a high performance, fixed setting control engineered for demanding HVACR applications, particularly those utilizing R410A refrigerant. This high pressure cut out switch features a SPST (Single Pole Single Throw) normally closed contact configuration, calibrated to "open on rise" at 600 PSI cut out and automatically reset (cut in) at 475 PSI. Built with a tamper proof, hermetically sealed sensor, the 43335 ensures long
