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.
