Switchable Line-in Jack

[seani]

Hi,

I have a Tivoli Model 1 radio that can accept auxiliary input by a
standard stereo jack on the rear. Unfortunately on this model, you cannot
switch between the radio and aux-in via a switch: connecting the jack
turns off the radio.

Is it possible to get a jack with it's own switch so that the cable can
remain handily in place, without constantly plugging and unplugging?

Thanks

Sean
