High pressure switch (Bosch part no. 8733955614) functions as a hard‑wired safety interlock for Bosch heat‑pump and outdoor condensing equipment, designed to interrupt compressor and outdoor fan operation when refrigerant head pressures reach unsafe levels. Bosch IDS service documentation shows HPS devices open to stop compressor/fan above ~580 PSIG and reset below ~435 PSIG, delivering straightforward over‑pressure protection that simplifies troubleshooting and reduces risk of compressor damage.
