Key Features and Benefits of the Electric Rearview Mirror Switch H4373040022A0
Built to Endure the Cab Environment
Heavy-duty truck cabs endure constant vibration, temperature swings, and dust intrusion. This Electric Rearview Mirror Switch H4373040022A0 FOTON fights back with a fully sealed housing that resists moisture, particulate contamination, and mechanical shock. As a result, the internal contact structure stays clean and responsive throughout the switch's service life.
OEM-Grade Material and Construction
- High-Strength ABS Plastic Housing — Delivers impact resistance and UV stability while keeping weight minimal.
- Anti-Slip Rotary Knob — Textured surface ensures positive grip even with work gloves, allowing precise mirror angle selection.
- Precision Internal Contacts — Gold-flash or silver-alloy contact points minimize electrical resistance and prevent arcing over thousands of actuation cycles.
- Sealed Dust & Moisture Protection — IP-rated enclosure guards against cabin contaminants that degrade cheaper aftermarket switches.
Direct Fit, Zero Modification
Because this switch matches OEM dimensional and electrical specifications, it drops directly into the existing dashboard or door-panel cutout. Consequently, technicians save valuable labor time — no wiring adapters, no bracket modifications, and no recalibration needed. The connector plug mates with the factory harness on the first attempt.
Stable Long-Term Electrical Performance
Internally, the switch routes mirror motor current through discrete position detents. Each detent locks positively, preventing accidental mirror drift caused by road vibration. Furthermore, the low-resistance circuit path minimizes heat buildup, extending both switch and mirror motor longevity.

Frequently Asked Questions (FAQ)
Is this Electric Rearview Mirror Switch H4373040022A0 an original OEM part or aftermarket?
This switch is manufactured to OEM specifications — meaning it matches the original part's dimensions, electrical ratings, and connector configuration precisely. It functions as a direct replacement for the factory-installed unit in FOTON Auman trucks, delivering identical performance without requiring any modification.
Will the Electric Rearview Mirror Switch H4373040022A0 FOTON fit my specific truck model?
This part is designed for FOTON Auman series heavy-duty trucks that use OEM part number H4373040022A0. To confirm compatibility, simply cross-reference this number against your truck's original parts catalog or provide your VIN, and our team will verify fitment for you.
How does the sealed design protect the switch internally?
The housing incorporates gasket seals and tight-tolerance mating surfaces that block dust particles and moisture from reaching the internal contact assembly. This is critical because contamination on contact surfaces causes intermittent operation or complete failure — a common issue with non-sealed aftermarket switches.
What is the expected lifespan of this mirror control switch?
The switch is rated for a minimum of 50,000 actuation cycles under standard operating conditions (-40°C to +85°C). In typical fleet use, this translates to several years of reliable service before replacement becomes necessary.
Can I install this Electric Rearview Mirror Switch H4373040022A0 myself?
Yes. Because it uses the OEM connector and mounting dimensions, installation is straightforward. A technician simply removes the old switch from the dashboard or door panel, disconnects the harness plug, connects the new unit, and secures it in place. No special tools or programming are required.
Does this switch control both left and right mirrors?
Yes. The rotary knob includes a left/right selector position, allowing the driver to toggle between mirrors and then adjust the selected mirror's angle using the same control. This mirrors the original OEM functionality exactly.
