Abstract
A method for configuring button keys on a membrane includes the steps of: mapping the membrane under the conditions of without jumping and without generating ghost keys; gathering adjacent button keys on a same cluster; defining a button key configuration chart according to each cluster; and linking circuits of each button key in each cluster to a flat cable of the membrane. Then defining total number of various composite keys; locating the composite keys to be not co-linear or cross co-linear on the X-axis or the Y-axis of the matrix scanning lines; and mapping other adjacent button keys without the jumping.
