With continuing reduction in product size, the required space to accomplish a switch with good tactile feedback is reaching it's threshold. Elastomeric switches, for example, require a minimum height to allow for the rubber dome to collapse or buckle and produce a change in actuation force which the user perceives as tactile feed- back. Non-collapsing elastomeric switches require less space, but do not provide the tactile feed back. Some electronic products, such as microwave ovens, take advantage of these low profue and low cost switches and provide an audible beep feedback once the switch is actuated.
