Although micro switches in cars are small, they are the "invisible commanders" for power window lifting, door lock control, and light adjustment. When the switches become unresponsive after long-term use or even fail suddenly, the culprit is often "minor issues" with the micro switch contacts: arc ablation and copper sheet oxidation. However, choosing the right lubricating grease can easily solve these problems.
The contacts of micro switches are mostly made of copper. When working in an environment with continuous power supply and vibration for a long time, they are prone to the following troubles:
Arc ablation: Tiny arcs are generated when the switch is turned on or off. Repeated ablation will make the contact surface rough, leading to poor contact. A certain automobile manufacturer once saw after-sales complaints about window switches accounting for 15% due to this problem;
Copper sheet oxidation: Moisture and oil stains in the car compartment will accelerate the oxidation of copper contacts, forming green copper rust that blocks current transmission. At best, this causes switch jamming; at worst, it leads to complete failure.
Baoxing BX-450 series contact switch lubricating grease is specially designed for the contacts of car micro switches, accurately meeting the core needs of "arc suppression and copper oxidation resistance". Its special formula forms an ultra-thin protective film on the contact surface, buffering the arc impact when the switch is turned on or off and reducing ablation marks;
Additives in the grease can firmly adhere to the surface of copper contacts, isolating moisture and oil stains. Even near the high-temperature and high-humidity engine compartment, it can prevent copper sheets from oxidizing and rusting;
It is suitable for automobile working conditions, with stable performance in a wide temperature range of -40℃ to 150℃. Whether in severe cold or extreme heat, it maintains lubricating performance without solidifying or flowing, perfectly adapting to the complex operating environment of cars.
Baoxing provides free sample testing. Whether for new car production and assembly or after-sales maintenance and replacement, it can provide stable protection for the contacts of car micro switches. Feel free to consult us if you have needs!
