Abstract
An audio and/or visual signal device is mounted on a pinball machine for signaling to the area surrounding the machine that a replay game or the like has been awarded. The signal device is connected through a relay to a source of electric power. The relay is energized by a magnetic reed switch adapted to be mounted in close association with a solenoid operated knocker within the machine so that the switch is magnetically closed when the knocker is operated.
Claims7
In combination,
- a pinball machine which includes an internal electrical circuit having an electronic award means including a solenoid actuated upon the accomplishment of a predetermined feat,
- a first electrical wire means electrically connected at one end to said internal electrical circuit and adapted for connection at the other end to a source of electric power,
- an award signaling circuit including a magnetic operated switch means positioned within the magnetic field of said solenoid for closing of said switch means in response to actuation of the solenoid, a relay,
- means operatively electrically connecting said switch means to said relay whereby the relay is energized in response to closing of said switch means,
- a signal means actuatable for signaling to the area surrounding the machine that an award has been won,
- means for operatively electrically connecting said signal means to the relay for actuating said signal means when the relay is energized, and
- a second electrical wire means electrically connected at one end to said award signaling circuit and adapted for connection at the other end to a source of electric power,
- said award signaling circuit being free of any electrical connection to said pinball machine circuit apart from said first and second electrical wire means.
