Abstract: A system for determining switch condition in an amusement device having at least one triggering switch is provided. The system comprises a first circuit for generating a first reference electrical signal, a second circuit linked to the at least one triggering switch for generating a first condition electrical signal, and a comparing circuit connected to the first circuit and the second circuit for comparing the first condition electrical signal to the first reference electrical signal and for generating an output electrical signal indicative of said switch condition based upon the comparison. Specifically, the output electrical signal will indicate if the switch is open, if the switch is closed, if the switch is electrically connected (wiring intact), or if the switch is electrically disconnected (wiring broken).
