Description

Technical Field

[0001] The utility model mainly relates to the technical field of automobile seat heating and ventilation switches, in particular to an automobile seat heating and ventilation switch. Background Art

[0002] Large vehicles are generally equipped with heated and ventilated seats. To meet passenger needs while optimizing space, heated and ventilated seat switches have emerged. One type of existing multi-function seat adjustment switch only provides a switch signal, requiring a separate controller to drive the motor, increasing costs and increasing failure rates. Another type of switch uses multiple connectors for wiring harnesses, which is inconvenient for component production and subsequent assembly. The switch is typically mounted on the side panel assembly, surrounded by other components, and then assembled to the seat assembly, making it difficult to connect the switch wiring harness. Existing 12-way switches of this type use a combination of rocker and slide switches. The slide switches have a weak return force, are prone to sticking, and have a poor feel. These switches use a light guide plate to distribute the point-shaped light source on the main circuit board into a narrow, elongated area, resulting in uneven light distribution and unsatisfactory results. Furthermore, the connectors on heated and ventilated seat switches lack anti-detachment features, making them prone to disconnection during use.

[0003] Therefore, we provide a car seat heating and ventilation switch to solve the defects of the existing technology. Utility Model Content
