Q: What is the function of WG2209280026?
A: This reverse light switch is mounted on the gearbox. When the truck shifts into reverse gear, the switch closes the circuit to turn on the rear reverse lamp. It also sends reverse signal to ECU for reverse buzzer or rear view camera. The circuit cuts off once gear exits reverse position.
Q: Where is this switch installed and which models fit?
A: It is screwed onto the gearbox housing. Suitable for SINOTRUK HOWO T5G and new HOWO heavy trucks. One piece per vehicle.
Q: What are the product features?
A: 1. 2-pin connector, normally open type, OEM thread size for direct replacement.
2. Mechanical plunger trigger design, resistant to continuous vibration of heavy duty truck.
3. Good sealing performance to prevent gear oil leakage.
4. Fast response when engaging reverse gear.
5. Compact size, easy installation and maintenance.
Q: What material is this reverse switch made of?
A: Main body: brass alloy for corrosion resistance. Seals: NBR oil-resistant rubber. Internal contact: conductive alloy. Connector housing: PA66 reinforced plastic, oil and heat resistant.
