Weird switches in OoT

In the Forest Temple's east courtyard, there's a switch in a balcony which drains the well. This switch is a red colour, different from the typical beige switches in the game. After activating this switch, Link may step on it again to deactivate it. This is bizarre and makes no physical sense, and I believe it to be a mechanic unique in this game. Also, there is no reason to do it, as the well being flooded only serves to hide a chest at the bottom, and going to the bottom with the iron boots does not reveal any secrets. This being very odd, I intend to continue investigation for additional reversible floor switches.

Side note: The drained well has a river flow between two grates, potentially leading to the clock town sewer? I say this because of the apparent location in the lost woods as well as the twisted corridor Link goes through to get there from Hyrule (of which there are 2 in the Forest Temple)
