Regular buttons are small rectangles that are attatched to either the floor, a wall or a ceiling. Unlike colored buttons, regular buttons only come in one color, which is white. They are described by Chris as a "glowing, white...thing," suggesting that normal buttons glow. Regular buttons appear to work in water, much like blue colored buttons.
In order to activate a button, any character must either step on it or push against it. it does not matter from which direction it is hit from to activate it.
Some buttons may be located in toxic water. Only Claire is able to activate these buttons because of her bouyancy abilities.
