    My 2 year old grandsons favourite toy, an Early Learning Centre keyboar
    has stopped working and he is heartbroken.
    On dismantling the thing I found that the on-off / volume contro
    switch has developed an intermittent fault. If pressure is applied t
    the body of the potentiometer it works fine but remove the pressure an
    then nothing.
    The switched pot. is a 16mm diameter 10k one with the switch mechanis
    exposed on the back so that the switching operation can be easil
    seen.
    I desoldered it and took it to Maplins in Glasgow thinking I would hav
    no problem in getting an exact replacement but, of course, nothing i
    that simple!!
    It seems to be an obsolete type and none of the possible replacements
    was shown would fit the circuit board holes and seemed to be a powe
    contact short.
    Does anyone know where I might find a supplier of apparently obsolet
    switched pots. ??
    Any help would be greatly appreciated
