What is the translucent cover over the master switch for?
It is a removable guard intended to reduce accidental operation of the master switch.
Remove the cap to operate the switch, then replace it afterwards.
Because the guard is translucent, the illuminated switch remains visible while protected — a small piece of plastic doing a rather useful job.
