AI Technical Summary
The existing automotive wiper switch structure has insufficient waterproof performance due to its metal contact structure, and cannot meet the IP54 waterproof requirement.
It adopts a non-contact design with optocoupler switch and impeller. Signal output is achieved by the rotation of the impeller relative to the optocoupler, and a collar is set on the roller as a waterproof wall to prevent water from entering.
The waterproof performance of the wiper switch has been improved, its service life has been extended, and it meets the IP54 waterproof requirement.
