| This is a picture of a Panel District frame (1933). For size purposes see switchmane. This frame could handle up to 60 outgoing trunk calls. 30 on each side of the frame. To the left of the switchman from the bottom up are the clutches, terminal banks, selector rods and brushes and the commutator bank at the top. |
