Abstract
An electronic control circuit is provided for controlling the operation of pinball machine flippers. Each flipper is operated in response to the energization of a single solenoid coil in which the same winding is energized to place the flipper in an actuated position and to hold the flipper in the actuated position. When a flipper switch is activated, a full wave rectified voltage is applied to the solenoid coil to place the flipper in an actuated position. When the flipper has been sensed to be in the actuated position, only a partial phase controlled voltage is applied to the solenoid coil to hold the flipper in the actuated position until the flipper switch is deactivated.
