Abstract
An externally connectable control unit for a portable radio includes an array of contacts matching a similar array of contacts on a portable radio. At lest one control switch is electrically connected with such connector contacts and disposed internally of a switch housing structure. The internal switch is located in association with a recess formed in the housing and a removable plug is friction-fitted within the recess so as to establish a first electrical condition of the control switch--but which is also capable of being manually pulled out of the recess to establish a second electrical condition of the control switch. The meaning to be associated with the switch is determined by a programming device in the control unit which interfaces with the portable radio circuits and is utilized to perform predetermined radio functions. One or more additional switches may also be located on the switch housing (e.g., externally) so as to provide additional convenient control over still other radio functions identified or 'programmed' by a predetermined impedance built into the control unit and connected across a pair of its connector contacts.
