Abstract

As pagers continue to shrink in size, it is impor- tant to get the maximum functionality from every component. Each part needs to be used for multiple functions whenever possible. This invention shows how an elastomeric switch pad can be used as a shock pad and how the display assembly itself can be used to activate the switch pad. Use ofthis method reduces the number of components required during the assembly ofthe radio and the space required for buttons on the face of the radio. In addition to these benefits, this invention Will also improve the radio's resistance to direct impact LCD fractures and increase the user's intuitive operation ofthe radio.

by Don Guthan, Dan Troutman and Leo Quintero

As pagers continue to shrink in size, it is impor- tant to get the maximum functionality from every

component. Each part needs to be used for multiple

functions whenever possible. This invention shows
how an elastomeric switch pad can be used as a

shock pad and how the display assembly itself can

be used to activate the switch pad. Use ofthis method

reduces the number of components required during

the assembly ofthe radio and the space required for buttons on the face of the radio. In addition to these

benefits, this invention Will also improve the radio's

resistance to direct impact LCD fractures and increase

the user's intuitive operation ofthe radio.

  This invention uses an elastomeric switch pad display is depressed, the elastomeric switch pad wall sandwiched between the display assembly and the collapses and allows the conductive pad on the switch main PC board. The switch pad has curved ribs at pad to come in contact with traces on the main PC the center of the pad which provides a rocking motion board. It is the shorting of the traces on the PC for the display. This rocking motion assists in using board which is c...
