Sourcing YC1Z-19E561-AAA A/C Pressure Switch FAQs
Why is the 0.7 kg/cm² cut-off logic vital for the Ford Transit fleet?
Commercial vehicles like the Ford Transit are subject to high vibration and heavy usage, which increases the risk of slow refrigerant leaks. The YC1Z-19E561-AAA switch monitors the suction side pressure; by cutting off at 0.7 kg/cm², it ensures the compressor does not operate without sufficient lubrication carried by the refrigerant. Our precision calibration prevents expensive compressor seizures for your fleet customers.
How do you guarantee the leak-free performance of the M12-P1.5 female fitting?
Low pressure switches are prone to "seepage" over time. We utilize a high-density alloy for the M12 housing and a premium internal diaphragm that withstands millions of pressure cycles. Every YC1Z-19E561-AAA unit undergoes 100 percent vacuum testing during manufacturing to ensure that it maintains a perfect seal against the accumulator Schrader valve.
Does this switch support the electrical parameters of Motorcraft YH-1712?
Absolutely. We have mapped the electrical resistance and switching speed to perfectly match the original Motorcraft YH-1712 specifications. This ensures that the engine control unit (ECU) on the Ford Transit and Focus models interprets the signal correctly, allowing for smooth compressor cycling and original HVAC performance.
What customization services do you provide for Top 100 wholesale brands?
We offer a complete OEM/ODM package for our high-volume importers. This includes high-definition laser marking of your brand logo and the YC1Z-19E561-AAA reference on the switch body. We also provide customized industrial-grade boxes and multi-language instruction inserts to help you build professional brand authority in your local market.
What is the lead time for bulk wholesale orders for European and American markets?
We maintain a fixed 60-day manufacturing lead time. This timeframe covers precision assembly in our IATF 16949 facility, rigorous pressure calibration, and final quality audits. Our commitment to this schedule helps our B2B partners maintain stable inventory levels and avoid the stockouts common in the aftermarket.
How do you package the switches to prevent terminal damage during bulk export?
Each YC1Z-19E561-AAA switch is individually sealed in a moisture-proof industrial bag, with the electrical terminals protected by a custom-fit plastic shroud. For bulk export, we use reinforced, double-walled export cartons with internal dividers to ensure that every unit arrives at your warehouse in pristine, ready-to-sell condition.
