A microphone having a push to talk switch button extending through a slot in one side of the microphone and a channel selector switch knob extending through at least one other slot in the microphone. An interlocking structure, having at least one finger extending from an extension member on the push to talk switch button, engages and locks with a plurality of alternating teeth and spaces on the channel selector switch knob. During a transmit mode of operation, the push to talk switch, having the interlocking finger, engages in at least one space between two of the teeth of the channel selector switch knob to prevent rotary movement of the channel selector switch knob and switching of channels during the transmit mode of operation of the microphone.
