Add line in to electret microphone and mute the microphone when plug is connected

My next idea was to use a transistor and an inverter to cut off the microphone when the switch is closed: However I don't know which part or circuit to use as an inverter. … Is there an inverter I could use? Or another circuit design? Thank you! …
