POP* BUMPER* SCORING* SWITCH
FIGURE 1
The pop bumper scoring
switches on Gottlieb's pinball
game, "Black Hole", have
been changed to eliminate the
mechanical wear on the switch
caused by the insulating yoke
slamming the scoring switch
closed when the pop bumper
is activated. Gottlieb will now
use the configuration shown in
Figure 1 on all of its future
games. A contact of the
switch now rests atop the
insulating yoke, keeping the
switch open. When the pop
bumper is activated, the
switch closes by just the
spring tension of the contact,
allowing for a more reliable
switch.
