Abstract: Push buttons utilizing dome switches are often preloaded to take up any tolerances in the push button design causing a gap and provide consistent tactile feedback to a user. However, conventional push button preload techniques can be costly and difficult to consistently reproduce during push button manufacturing. A new pre-load design does not require pre-depression of the dome switch to close the gap, which permits a more forgiving tolerance to manufacturing variations.
