ABSTRACT:
This invention is a coin operated switch which may be incorporated into coin operated machines such as video games to reduce cheating of the credit granting feature of the machines. This invention incorporates two electromechanical switches and circuitry which further use the existing machine circuitry to time the travel of a coin between the switches and to grant a credit on the machine only if each switch is tripped and released in the proper order and within the predetermined elapsed time.
