摘要: A key unit of a keyboard apparatus having at least one bumper extending from the key unit for cushioning the impact of the key unit against the enclosure of the keyboard apparatus when the key unit assumes a depressed position and/or when the key unit resumes a non-depressed position, thereby eliminating or reducing the feedback noise, while retaining the benefits of a pre-loaded feature for the key unit.
