Abstract
A coin chute trigger assembly having separate coin paths for nickels, dimes, and quarters. Intentionally, the dime coin path is made at least twice as wide as the thickness of a dime in order to prevent hangups and jams. A trigger included in each coin path is operated in response to deposit of the appropriate coin through the coin chute or path and causes operation of an included pair of switching contacts.
