i have an illuminated switch. now normally lets say you wire it like this:
1: power
2: ground (to light up light)
3: acc
now my problem is i have to switch the GROUND off the item, not the power. so how do i do that and still make it light up?
is this right:
1: acc negative
2: ground (to light up light)
3: ground (to ground item)

well obviously i CAN'T do that or i would have already. my question is will it work? the reason i can't is because it's a 3-way switch, choosing one of two grounds. it acts as on-off-door like the dome light. since the car is wired using ground switches, there is no power supply i can use to determine when the door is open, only a ground. therefore i'm using a ground switch. but WILL IT WORK?

i have neons up under the dash, and i have them wired LIKE the domelight. so that i can turn em on, or off, or have them come on when the doors open.
i have a 2001 celica and it uses a constant 12v to the dome light, and the ground determines on/off/door.
i don't want to get all complicated with relays and stuff for something this simple, i just need a light up switch.
on a side note, i would really want a blue light up switch of some kind that looks good. i was thinking an led-tipped toggle. but i can't seem to find anything that is good that is on-off-on and have blue lighting. anyone know of something like that?

No, that will not work.
The bulb needs 12 volts at the acc area and a ground at the ground area to work. the filament is between those connections.
One way is to wire it up the first way and go through a relay to switch the ground.
another way, I have not tried this and I do not know if it will work, is to wire the 12 volts to the ground connection and put the ground on the power connection and put the ground wire to the item on the acc connection.
Good luck,
Tom

Wire power to the POWER lead, ground to the GROUND lead, then your ACCESSORY to the ACC lead. When you switch it on, power is passed through the light, and to the Accessory. They are both grounded through the GND lead. I have used them before, if put on backwards, the light simply illuminates when OFF. . . I have done that once, just switched the ACCY and POWER applications.
