Marble track - 1 pass switch (Gravitrax compatible when using my 6 exit basic tile)

How to feed only one ball to a cannon or a hammer? Use the 1 pass switch! It allows you to control the ball flow and only feed one ball to either the left or right and let all other balls pass through the other exit.
