The YK-A Low Pressure Switch is a compact capsule pressure safety control engineered for air conditioning and commercial refrigeration systems. Designed with an automatic reset mechanism, this switch safeguards compressors against loss of charge or low suction pressure conditions by opening the electrical circuit at 0.3 MPa (3.0 bar / 43.5 psi) and automatically resetting when system pressure rises to 0.45 MPa (4.5 bar / 65.3 psi). Featuring a standard 1/4in female flare brass connection with an internal valve depressor and pre-wired flying leads, it delivers direct-mount pressure protection for refrigeration engineers and OEMs.
