i got the dedenbear fully adjustable micro switch in my 4 link super pro/top dragster. i'd call it a medium size button head. i also have the dedenbear, what i call "ray charles", xl headed button in our blown pro top outlaw dragster/heads up car. It came in the car when we bought it. I really dont care for the oversized button. to me its just way to much surface area. you have to be sure your pulling straight off or your not very consistant.
