Deathcon switches allows access to the door that says "Access to 151 required". you need to pull all 5 of them. they can be found on the upper and lower level of level 2. once you pull all 5 a annoncement will go off and if you take any teleport, you will teleport to inside that room. inside it is the PaP which will disappear within a certain time.
the box can be anywhere. my advice is if you are at the basement, look through all the windows and if you see a blue glowing light, thats the box, if you dont its on the upper level.
Hope this helps
