collaborated with an automotive interior manufacturer to customize hardware button brackets for car steering wheels. Using high-strength zinc alloy material, through precision die-casting and grinding processes, the bracket is light in weight and high in strength. The conductive contacts are precise, the buttons are sensitive in response, and the pressing is smooth without jamming. The wear-resistant button cap design has a service life of more than 500,000 times. The surface is matte treated, scratch-resistant and wear-resistant, suitable for volume, cruise and other buttons of multi-function steering wheels, easy to install and fitting the steering wheel shape. This customized bracket helped the partner increase the steering wheel product qualification rate to 99.8% and improve the interior score of supporting models.
