Any idea where can I get the schematics for the dome light dimmer to be used in car. Which means that when I open the door, the light will light up and when closed, the light will slower dim and off.
The first link shows all the door switches and a selector switch to determine which means , if any , to turn on the light. The text below explains it all. The second link simplifies it all. To answer your question, yes the light will be on full brightness as long as door is open.
When the door is closed, C1 eventually gets up to 12 V. When the door is opened, C1 is discharged through the switch and D1. There is no current limit in this circuit, so the current will be quite large. A 1N4148 is only rated at 450 mA peak, so the circuit should really have at least 25 Ω in directly series with C1.
It isn't good for the capacitor either. The switch will be OK with a capacitor of that size, but it is good practice to limit discharge rates.
I am so sorry, I couldn't understand what you are saying, still very fresh to this kind of stuff. Please if you could do you mind showing me a schematic? Thank you.
