4-Person Panel

A Blue Switch is an object in Mario & Luigi: Partners in Time. It has four blocks symbols on it, symbolizing that when the whole party is on top of it, it will be pressed into the ground, and will open up a passageway in front of the bros. so they may progress forward. They are common throughout the game, in every area, in fact. It has a rarer variation, the Yellow Switch, which functions identically except it only needs to brothers to activate it.

Blue Switches also appear in the Paper Mario series. Blue Switches are one-time use switches that activate an important change in the environment, such as a bridge being built or a staircase appearing. If one is present in the environment, it is needed to be hit on to move on through the area.
