PTT foot switch for connection to 6-pin CB radio devices such as the Albrecht AE 6491.The foot switch is connected directly to the microphone jack of the CB radio. The hand-held microphone is plugged into the connection cable of the foot switch and should be placed near the talking person. If the foot switch is pressed, it triggers the PTT transmission button (Push-to-Talk) of the microphone. You no longer need to take the hand-held microphone in order to transmit radio signals.
