The switch is capacitor-filtered to virtually eliminate switch "pops" but they can drive the board op totally out of his/her mind during a stage performance. Switches are known to get "switched" by curious performers either intentionally or accidentally. If you have a choice, it may be wise to apply a bead of Lok-tite(R) or hot glue to the switch in the "on" position to keep your board op reasonably sane.
