Bosch High Pressure Switch (PN 8733941857) is a field-replaceable safety device for HVAC and heat pump systems that monitors system pressure and opens to remove power when pressures exceed safe limits, protecting compressors and downstream components. It installs into unit control circuits to provide dependable mechanical overpressure protection.
