NOTE: The white-filled groove in the button indicates the roto-ring position.
When the roto-ring is in the counterclockwise position the button position
is normal and may be depressed independent of the roto-ring. Rotating the
ring to the extreme clockwise position depresses and latches the button.
The roto-ring has spring return action from any clockwise position except
the latched position.
