A simplified, low voltage control circuit operates the motor for a pinsetter intermittently, instead of having the motor operate continuously. The low voltage system is mounted in the existing electrical control box for the pinsetter. The control circuit includes the relay for turning the high voltage motor circuit on or off, and a low voltage input electromagnet coil for the relay. To operate the motor control relay, circuitry is coupled to the existing 24 volt (low voltage) circuit of the pinsetter, and the control circuit includes a switch coupled to the clutch between the motor and the pinspotter mechanism, and a second switch which is coupled to the deck filler mechanism to indicate when the pinspotter deck is full. In addition, a delay circuit is provided to maintain the relay energized and the motor turned on, for a brief period of time until the system completes its cycle after an indication is given that the pinspotter deck is full. An additional bypass switch is provided to energize the relay and turn the motor on regardless of the state of the clutch or the deck.
