Why do some microphones with a switch have a stop screw locking them in the "On" switch position?

Many performers take the microphone out of the holder and move around the stage to give a better performance. Unfortunately, this means the switch can be moved accidentally.
To prevent this, the switch can be locked so that it can be controlled only from the mixing console – especially useful at events where many differing groups and musicians take the stage.
