As the door is latched, the Door Latch cam rotates the Door Latch Sensor CCW, allowing the B+ wire to
drop and contact VER (Figure 2-6). Power is now made and darkslide occurs. The Film Shade moves to
the left into its blocking position, then returns.
On its return, its lug pushes the Dark Slide Link to the right (Figure 2-7), out of the way, allowing the
Power Actuator assembly to pivot CCW back down again. This allows VER to break contact with B+,
turning off power, and to contact GND again.

Note: With an erected camera, the Dark Slide Link/Power
Actuator are not needed for darkslide power. Instead,
the Erect Link and Erect Sensor, described later, open
VER to GND, and close VER to B+.)
