The Time Stop Switch is a gimmick that appears in the Sonic the Hedgehog series. As its name implies, it stops time.
The Time Stop Switch comprises of two units: a pedestal and a half-cut ball. The pedestal is black, decagon-shaped and is decorated with markings with a cream-colored border around it. The center is raised slightly to form a round hole from above and there are also six holes on the surface each emitting yellow light. This hole is surrounded by a lavender border. The ball is decorated with markings similar to the pedestal's and has two small rings orbiting around it.
In Sonic Adventure 2, and its enhanced port Sonic Adventure 2: Battle, the Time Stop Switches are found exclusively in Cannon's Core. When used, it stops the flow of time, freezing enemies, obstacles, the background and the elapsed time in a Stage, though it cannot freeze doors and some trap platforms. However, each Time Stop Switch lasts only for a specified period before time returns to normal.
To use it in gameplay, the player must simply touch the orb or shoot it. The Time Stop Switch will then beep and light up intermittently until its effects end.
