I have an old table lamp which *used*
to exhibit the
following properties when the key was turned:
1. First clockwise click: the base would light up.
2. Second clockwise click: the standard bulb would light up,
and the base would turn off.
3. Third clockwise click: both base and standard bulb would light.
4. Fourth clockwise click: all lamps would turn off.
However, the socket no longer works, and I'm looking to replace it.
After dismantling, it appears that the socket has three wires leading
into it, and it has 250V, 250W printed on the side.
My question: is a replacement socket hard to find, and is there
a standard description of it which would help me locate it on the 'net?
