This switch releases two large, glass spheres containing green slime - each at the top of a hidden incline to either side of the pit. As the spheres begin rolling down towards the pit, the walls next to the pit slide open to allow the spheres to impact each other and shatter over the pit, draining their contents onto the hapless adventurer in the pit.
Of course, the spheres would roll slowly and loudly enough to hopefully give the other adventurers time to realize something was amiss and, again hopefully, rescue their comrade from the pit before the spheres crash into each other, shatter, and fill the bottom of the pit with green slime.
Not to defecate on your creativity, but why wouldn't the builder of this trap simply keep some green slime in the bottom of the pit instead of constructing some elaborate slime-filled sphere-rolling mechanism?
Because the green slime would react with the acid in the bottom of the pit. That's why you drop it in later. First you land in the acid, then the green slime lands on you, then the green slime drips into the acid and it explodes. From the top of the pit it looks like a flaming bar drink when it's all done.
