Magneto Wall Switchboards


N586 shown pictured to the right.

n586.jpg (9675 bytes)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.
