Abstract

See full text

A coin escrow device has a coin jam detection mechanism that uses a magnetic switch. Magnets are connected to supports which move close to and away from the magnetic switch as a result of a coin deposit and the movement of the escrow device's gates. When a coin jam occurs, the magnets are positioned such that the magnetic switch is on.
