A Drop Target is a flat mechanical target that is held up on a small ledge and when hit with a ball, is moved backwards and dropped down via a small spring. There are generally switches for both the Up and Down positions but just a single Down switch will work. They can be arranged as single targets or in rows.

Every manufacturer has their own designs and use a variety of switch types to detect the target position - Williams used optos while modern Stern games use microswitches.

They are also available in an Inline format.

+A Drop Target is a flat mechanical target that is held up on a small ledge and when hit with a ball, is moved backwards and dropped down via a small spring.  There are generally switches for both the ''Up'' and ''Down'' positions but just a single ''Down'' switch will work.  They can be arranged as single targets or in rows.
-For a drop target bank, only a minor check is needed after every drop target it.

-Give a reward for hitting the drop targets in order. Example: ''Centaur''.
