The Red Dot 71R6093 high pressure cycling switch is designed for accumulator-based mobile HVAC systems used in Ford and Sterling truck applications. It is a normally closed cycling switch that opens at higher pressure (46 PSI) and closes as pressure drops (23 PSI), allowing the system to cycle properly while protecting components from abnormal pressure conditions.
This switch features an M12 x 1.5 female thread fitting and an integral prong electrical connection, providing a compact, reliable installation without the need for an external harness. Its defined cycling range and OEM-specific fitment make it a common service replacement for Ford/Sterling HVAC systems.
