Abstract

Portable radio products' control push button switches can be functionally expanded by allowing a radio fea- ture to be controlled by a dual switch closure. A single press of a control button would activate the ~switch's normal function, but a quick double closure of that same switch would control a different feature. This article pri- marily addresses two different switches: the radio's or remote microphone's PIT switch and the LED display back lighting switch. The concept could be applied to any of the radio's pushbutton control switches.
