Looking for a 12 volt relay capable of switching up to 5 amps that is triggered by a 12 volt / 20 ma max.  Normal auto relays are triggered by 150 ma I believe.  Thank you.

You could use a couple of Transistors instead.

Your correct standard relays usually fall betwen 130 - 160 mA. I've seen radio shack has other relays (for circuit board use) that take probably half that, but not sure if they have any as low as 20mA. Also what exactly are you using as a trigger than only has 20mA avaialable?
