<p>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.</p> |
