Sourcing 88645-60030 from Professional Supplier FAQs

Does this switch correctly trigger the cooling fan at 1.52Mpa?

Yes. Every unit is tested on an automated pressure bench to ensure the Medium Pressure (MP) contact closes at 1.52Mpa. This is a critical feature for Toyota and Honda SUVs with large cabin volumes, as it prevents high-side pressure spikes by forcing condenser fan activation.

Can we order this SKU with custom private label branding?

Absolutely. For our "Top 100" importers, we offer laser etching of your brand logo and the 80440-S1K-003 / 88645-60030 cross-reference numbers on the sensor housing. We also provide custom-designed B2B packaging to help you establish brand authority in your local market.

What is the standard lead time for a mixed wholesale shipment?

Our lead time is fixed at 60 days. This allows for precise calibration of the trinary diaphragm and rigorous quality auditing under IATF 16949 standards. For high-volume clients, we recommend a rolling forecast to ensure consistent inventory replenishment.

How do you ensure the durability of the electrical terminals in high-heat engine bays?

We use high-temperature resistant polymer connectors and reinforced brass terminals to ensure zero signal loss. Each batch is subjected to thermal cycling tests (-40°C to 125°C) to guarantee the switch won't fail prematurely in the extreme environments typical of JDM engine bays.

Do you provide samples for technical verification before large-scale procurement?

We support technical vetting. We can provide samples for your quality control department to verify the pressure thresholds and thread accuracy. This transparency ensures that the 100-unit MOQ investment meets your professional procurement standards.
