Abstract
A lightguide for illuminating keypads within electronic devices, such as radiotelephones, supports additional components and is maintained in spaced apart relationship with a circuit board hosting electronic components. The number of separate components required within a radiotelephone is decreased and the amount of circuit board real estate available for electrical components is increased.
