The switch features a female thread of 7/16 - 20UNF (1/4 SAE) and is identified by model LH-654-694. It is used to monitor high and low pressure thresholds in automotive air conditioning systems.
The switch is configured with high-pressure (HP) off at 25 bar and low-pressure (LP) off at 2.0 bar, standard settings for R134a systems in heavy equipment and agricultural machinery. These thresholds ensure the compressor engages or disengages at safe operating pressures. The silver-colored switch is built to withstand vibration and temperature extremes typical in automotive applications.
Buyers for this switch include repair shops, fleet operators, and OEM parts distributors servicing brands like CASE, CHALLENGER, and VALTRA. The switch is a critical safety component, preventing damage to the AC system by cutting power to the compressor under abnormal pressure conditions. Confirm compatibility with your vehicle’s make, model, and refrigerant type before ordering.

Before ordering, confirm the switch’s part number matches your vehicle’s OEM or aftermarket requirements. Verify the thread type (7/16 - 20UNF) and pressure settings (HP 25 bar, LP 2.0 bar) are compatible with your AC system. Request the supplier’s compatibility chart for cross-referencing with other brands or models, as misapplication can lead to system damage.
Clarify logistics details such as lead time, packaging (e.g., individual or bulk), and Incoterms (e.g., FOB Guangzhou). This switch is likely shipped in small quantities, so confirm whether the supplier offers export-ready packaging with pressure-sensitive labels. Agree on payment terms (e.g., TT, LC) and any minimum order quantities, as these may vary for international buyers.
Upon receipt, inspect the switch for physical damage, correct part numbering, and thread integrity. Test the switch’s electrical continuity and pressure cut-off points using a calibrated test kit. Request a certificate of conformity or test report from the supplier to confirm the switch meets OEM or industry standards for automotive AC pressure switches. Document all tests for warranty or return purposes.
