Press to test!!

Well, had one of those moments at work last night. The one where as you are doing it you mind is saying NOOOOOOOOOOOOOOO but you action does not stop and after the fact it is followed up by, "please God make it go away".
I was doing a weekly check on an Air Bus A320. This involves doing a check of the standby power generation system. The guarded push button switch is marked across the top, STANDBY and under GEN. Below this is the PAX STANDBY emergency oxygen button, also guarded, but red..........Do you see where this is going??
Done this task more times than I can remember, but lifted the Red guard and pressed. Had the moment stated above and turned around to see approximately 200 passenger oxygen masks, plus toilets and cabin crew positions gently swaying back and forth. Fortunately I had some charitable co-workers who then lifted me out of the brown smelly stuff........Cost me a crate of beer though.
