There is a momentary button in my car that I would like to change to an actual on/off switch.
The signal comes out of the gauges. It's +11V 10mA. Pushing the button grounds it to the chassis.
I'm just slightly concerned that leaving it grounded for long periods of time could damage the gauges. I think there are other similar signals coming out of gauges that are grounded for long periods, but I haven't tested them yet to see if they are the same V and mA.
What'da ya think? Should it be OK?
Should I at least put in a diode? Which one?
Thanks,
