ABSTRACT:
A dual-coil solenoid for actuating pin ball game flippers having a high actuation and ball propelling force and a lower flipper and ball holding force. The solenoid includes low and high resistance coils placed in electrically parallel relationship across a source of electrical energy upon actuation of a flipper switch by a game player. Upon full deflection of the flipper and solenoid, an end of stroke switch automatically removes electrical energy from the low resistance coil thereby leaving only the high resistance coil energized to hold the flipper and game ball in position. A capacitance is positioned across the end of stroke switch to absorb electrical energy from the low resistance coil and to protect the switch. Diodes further protect both switch and the capacitor from excessive voltage transients.
