Guys, I have a small layout that is operated by a single Mobile Station 2 (60653).

I have one turnout equipped with the 74445 set, so it has it's own decoder.
I also have one 76391 signal with it's own digital decoder.
Pretty easy operation with MS2.

I would like to make some circuit tracks operate both the turnout and signal, while maintaining the digital operation still connected and working. Since it's a difficult access place, I would like to maintain some "override" function accessible with the MS2.

Technical question is:
So, how can I connect an analog switch and a digital decoder to operate the same device without making the analog switch burn the digital decoder?

Thanks!

[EDIT]
The idea is to make the contacts 1A and 2A (on the left) operate the turnout A (on the right).
So a train coming from 1A closes a signal 2A and keeps going to 1B.
And a train from 2A closes a signal on 1A and is switched to go to 2B.

So, since you guys didn't answer me, I took my chances and did the setup already.
I connected the circuit tracks directly to the output of one single digital decoder that operates the 2 switches at the same time. When the circuit track is activated, it electrify the electric switches directly.
I hope the digital decoder doesn't get bothered to be bypassed like this. (I mean, I hope this doesn't burn all the stuff).
