A very popular type of switchboard, being so simple in build, apparatus and
operation.
The case is made of fine hardwood matt polished, with a covering of hard fibre on the
front
face to prevent damage by the plugs, when being inserted into the jacks, and so preserve a
good
appearance.
The hand-restored drop indicators in the lines also give the clearing signal.
The connecting cords are fitted with a plug at each end, also a single cord and plug is
provided for operating purposes and as an alternative or stand-by to the latter, a single
jack is fitted,
which can be used in conjunction with any of the connecting cords to operate the
switchboard.
Night bell and switch.
For the operator's use a separate magneto telephone is required and should be installed
by
the side of the switchboard.
