Active switch question

Hello
Just curious. I have a Thunder 1A v3 guitar and have learnt from reading, from being told and from plain experience that you need to take the jack out when not in use to preserve the batteries. My question is couldn't it have been designed so that the active switch 'off' position isolates the batteries? I'm not much cop with electronics but on the face of it you'd think it'd be possible, with the advantage that there's no battery drain while playing without active, and of course when you forget to take the jack out. Has anyone mod'ed their circuits to do this or is there a good reason why not to or why it can't be done?
Maybe it requires a switch with two circuit breakers or something. If you know, please explain.

You can't use the active on/off switch.
Could fit another switch somewhere.
But you have one, take the lead out you lazy sod.

...well OK, I am actually. But also a forgetful sod.

It just seems more logical to me that the active switch should cut the battery. Although to be honest if there were a way to do it I'd probably be too lazy to do it.
Case closed.

All the active switch does is bring in the onboard amp, which is powered by the batteries obviously

Your jack just completes the circuit.

OK. Thanks for the diagram. Maybe what I'm asking could be achieved with a double pole/double throw switch although I suspect the existing switch might already be DPDT, with all poles used. All a bit beyond me, hence the question.

Anyway, I have a workaround which is to place the guitar rack more than a cable length away from the channel input.
