Switch door
The Switch door, sometimes referred to as a toggle door, is a tile exclusive to Chip's Challenge 2 whose function alternates between wall and floor. They are connected to wire, open every time the wire becomes active, and close every time the wire becomes inactive. Switch doors always retain a magenta border to distinguish them from normal walls and floor, which otherwise appear identical.
Switch doors are very similar to toggle walls in their mechanics, but differ in how they are controlled.
Objects on top of switch doors will not affect, or be affected by, a toggle. If a block is on top of a closed switch door, Chip can push the block off the door, although he cannot pass through it himself. If the block is on an open switch door, Chip will simply push the block as normal.
