ABSTRACT:
A rolling ball amusement device such as a pinball game comprises a frame carrying a playfield, and a ball-actuated switch carried with the playfield. The switch comprises a switch body which is movably and typically pivotably connected with a variable-position actuator wire to operate the switch in a manner which is dependent upon the position of the wire. A slot is defined in the playfield, with the actuator wire defining an arc section which is free of angled corners projecting upwardly through the slot. A rolling ball can depress the arc section to actuate the switch with essentially no "hang-up", whether or not the rolling ball approaches the actuator wire from a longitudinal or a lateral direction. Also, a spring urges the actuator wire upwardly out of the depressed position so that the actuator wire only occupies its depressed position when pressed into it by a rolling ball.
