Illuminated switches have three connections, input, ground and output. The bulb/LED is between output and
ground. I presume you've just not shown the ground connections on that diagram as Fritzing has no symbol?
I think you mean 1.4k and 1k. Use 1.5k and 1k as 1.5k is a more common value. You need one resistor
divider for every switch since each switch is a separate signal.
Another way to do this is use a resistor/zener divider, say 10k+4V7, or just use a >= 10k resistor and let the
input protection diode carry the current (not as robust though).
