The microphone is in-operable when a button is pushed, at least for all intents and purposes. The resistance of an average headset microphone is relatively high, 100-500 ohms if i were to guess. When you put a small resistor in parallel with a resistance this high it has a negligible effect on the resistance of the combination. For example if the microphone were 500 ohms and your switch put a 5 ohm resistor in parallel with it you would expect to read ~4.95 ohms of resistance total. |
