  • Patent number: 4360203
    Abstract: A rollover switch for pinball game includes a yieldable, and preferably elastic surface deformable between a position substantially level with the playfield surface and a position above the playfield surface. In one embodiment, the elastic surface is defined by a plurality of members connected by a hinge to support structure. The support structure defines a periphery, and the members extend inwardly from the hinged periphery. A plunger is provided to engage switch contacts as the members are advanced about the hinged connection. In another embodiment, the elastic surface is defined by a stretchable membrane which is deformable between a position substantially flush with the surface of the playfield and a position above the playfield.

  • Patent number: 4354681
    Abstract: An improved drop target assembly provides multiple target surfaces at a given drop target location. First and second target surfaces respectively are provided on first and second support members disposed in alignment such that the first member is in front of the second member, and the first target surface is in front of and shields the second target surface when the members maintain both targets in the above-playfield position. The first member is vertically moveable to drop the first target surface to a below-playfield position. This exposes the second target surface [exposed] for ball engagement. Preferably, a pair of switch contacts is provided behind the second target surface such that ball engagement of either the first target surface or the second target surface closes the switch contacts.
