Imagine opening a car door for an important guest — it would be quite awkward if the exterior door handle snapped back abruptly with a loud noise. Fortunately, this rarely happens because most exterior door handles are equipped with rotary dampers . These dampers ensure that the handle returns quietly and smoothly, enhancing the overall user experience. They also prevent the handle from rebounding and potentially injuring passengers or damaging the vehicle’s body. Exterior door handles are among the most common automotive components where rotary dampers are used.
