The Beam Swing is a gimmick that appears in Sonic Boom: Rise of Lyric. It is a simple pink beam that Amy Rose can use to swing on and jump.
Description
The Beam Swing is basically a pink beam which varies in appearance: in some chases it looks like a thin round pole while in other it is more rectangular in shape. It can found either sticking out as a lone pole from a wall or a scaffold. What makes it distinguishable from the Balance Beam is that it is much thinner and that it is always perpendicular to Amy when she looks forward on the path. In rare cases though, they are completely identical to Balance Beams in appearance.

The Beam Swing serves as a way for the player to traverse the areas using Amy's specific character abilities. When Amy touches with a Beam Swing, she will hook onto it with the edge of her piko hammer's head and swing around it until she dismounts, which will send her flying forward and upward through the air, where she release her piko hammer and grabs it again on the way down. In gameplay, this allows the player to make significantly long jumps and cross gabs that would be too wide to cross otherwise.
To use a Beam Swing in gameplay, the player just has to touch it with Amy to make her start swinging. Then, to make her dismount, the player has to press 
. However, if the player dismounts at the wrong time, which depends on the player's intentions, Amy will be launched in the wrong direction.
