Hi,
I have a .5 volt signal wire that needs to power a 12v car device. I thought of course put a relay on it, but from what I have been able to see - a 0.5v signal wont trigger a relay
Is there a special relay or something I can buy from radioshack or somewhere local to get this to work, or any ideas?
THANKS
Just curious, what are you trying to accomplish, and what are you using that supplies the .5V?

I am using a summit racing RPM switch, which is needing to trigger/power a vacuum solenoid for an intake manifold at 5300rpm.
The activation LED comes on at 5300rpm showing that it is working properly - and voltage goes from 0 to 0.5v so I know it's working... hardly. I checked the ground, blah blah
That doesn't sound like it is working. It should put out 12V, is it part#
SUM-830449 ? I also noticed it said some bs about a protection circuitry and internal fuse. Have you tried to meter the output when the when it is disconnected?

You might wanna try a simple transistor circuit, the only problem is that you will need about 0.65V to activate a transistor, however it might work with a 0.5V, you'll have to try. Let us know if you need any further help.
