Millennium 2 bypass A/B Box. DPDT switch wiring.

[Buffalo Tom]

How do I wire a DPDT switch with Millennium 2 bypass and also ground out the channel not being used?

[Buffalo Tom]

So this is how I wanna wire the switch for the A/B
But where do I connect the control wire?

[Buffalo Tom]

Its a rack mount design I'm doing with a heavy duty toogle switch and two Schneider LED pilot lights and they need 24V and draw 15mA. All the millennium bypass schematics are for 9 volt, can I just use 24 volt instead without changing any parts?

[MrStab]

or this, maybe?


for 24V, you will probably need a larger current-limiting resistor for the LED. According to datasheets, the 2n7000's max rating is 60V and max Reverse Breakdown for the 1n4148 is 75V, and i don't see you hitting current limits if you change that resistor, so i'd imagine you'd be okay but i could be wrong. space aside, there's no reason you couldn't limit the voltage to this part of the circuit alone.

edit: max gate-source current for 2n7000 is +/-18V, not 36V, so might not actually be advisable
