    Hi,

    I hope that this is the right place to ask - if not, please tell me where to
    go (nicely!)...

    I have an old set of uniselectors that are part of a clock I'm restoring. I
    would like to know more about the uniselectors and where I might get spare
    ones of this type. Indeed, how to restore/clean them would be a help too
    (they're rather grotty)!

    The markings on them are as follows:

    on the coil:
    "1/DCO/240
    T30338A
    250ohm"

    on the rotor:
    "1/DW1/14"

    on the back:
    "2203A
    4/30A S61/1"

    There are 3 sets of contacts, each with 12 different contacts. They are
    stiff and dirty, but will click round with a bit of help...

    Thanks for any help you can provide.

    Mike

    You might have more luck if you direct your enquiry to
    comp.dcom.telecom

    The numbers are reminiscent of the scheme used by BPO and APO
    particularly the S61/1 which is the "SerialNo/Item" No for that
    particular switch. The other numbers relate to the individual part S/I
    numbers.

    Generally, if you have some mechanical knowledge or you are good at
    pulling things apart and reassembling them correctly, uniselectors are
    fairly easy to get going. You just have to remember to clean
    everything and apply the appropriate lubricants in the correct spots
    and make sure the armature has the correct stroke and the various
    detents and pawls have the correct tolerances. You may be able to set
    these by trial and error but an adjustment procedure would be the best
    way to go for sure.

    I haven't done one of these for more than 40 odd years now.
