摘要

A button which is removable from and insertable into a keypad from the exterior of a housing containing the keypad. The button fits within an opening of the keypad and is formed with resilient fingers in its side walls. The fingers have interfering flanges at their lower ends. The flanges are chamfered to provide a camming action to deflect the fingers when the button is removed or inserted. <IMAGE>
