I made a switch-based rotating sector puzzle in one of my maps not too long ago, I'm not too familiar with rotating sectors yet I managed to pull it off first try using the convex door tutorial (as my effect didn't need the sector to rise, only to spin) :

Otherwise the more general rotate-rise sector tutorial is available here:

Sorry if I'm pointing you in directions that may look a bit obvious. If the one-time activation is your actual issue, I'd just close a door sector in front of the switch with a Gspeed in the 16000+ value range that gets triggered as soon as said switch is activated, preventing the player from reusing the switch (at least this very one, you could have another switch later in the map if you ever change your mind and want the player to be able to rotate the sector back later) by shooting it again, this implies you'd need to use a shootable switch though.
Normally I'd say you should use a Masterswitch actor for one-time activations (with or without delay) but here the constant possibility for the player to access to the trigger remains a problem unless you make that switch a touchplate with a hi-tag of 1. Remember you can design touchplates that don't have to be triggers; you could make it look like a floor switch of some kind, and since Touchplates will lower the ground of the sector they're in if you place them below ground level, you could make it some sort of one-time, player weight-activated ground switch that sinks a little once they step on it. You might or might not have to have the Touchplate facing down for the player to be able to trigger it from above though (which may or may not ruin the intended feel of the effect).
