The car window switch (also known as the window lift switch or electric window switch) is the 'human-machine interface' that controls the up and down movement of the car door glass. Although it may seem simple, it integrates various functions such as micro-motion mechanisms, circuit protection, anti-pinch communication, and backlight/touch control.

Technical features and manufacturing processes:

• High durability: The mechanical life span typically reaches tens of thousands of operations (over 50,000 cycles).
• Waterproof and dustproof: Has a protection rating of IP5X or higher, preventing short circuits caused by car washing or rainwater intrusion.
• Precise touch: The operation force is moderate, feedback is clear, it has advanced tactile sensation and a 'click' sound, enhancing user experience.

Common faults:

• Contact erosion/oxidation: Frequent switching of high currents (large starting current of the window motor) causes contact erosion, leading to poor contact.
• Internal circuit damage: Caused by water ingress, short circuits, or component aging.
• Mechanical structure damage: Button jamming, breakage, or failure to return to position.
• Backlight failure: LED or bulb burnout.

Fault symptoms:

• A particular window completely fails: The corresponding switch should be checked first.
• Can only go up but not down, or vice versa: Usually caused by damage to a set of contacts inside the switch.
• Failure of one-touch up/down or anti-pinch function: May require reprogramming or damage to the switch module.
• Button has no backlight: Affects nighttime operation.
