Headlight switch replacement?

My switch is kinda messed up. if it's not turned just to the point of turning the interior lights on, the cluster is dead.
What do I need to replace the switch?
I have the 'twilight sentinel' dial below it (despite not understanding how it works at all)
which one of these would work?

Not too sure, I kind of remember getting mine from the dealer years back. I have a spare one for $20 if you want it.

does it look like this?

I'll dig out the spare and take a look. I think the only visible difference between a regular one and one for a car with twilight is a few connections in the plug. My RMW came with the base switch and as a result my twilight never worked.

what the hell does it do?

Twilight sentinel is an automatic headlight system. When the slider is moved from the off position it will automatically activate the headlights when it gets dark out. On top of that, it will keep the headlights illuminated after you exit the vehicle at night. They will stay lit between 30 seconds to 3 minutes depending on where the slider is. To the left is less time right is more time.

Does the headlight switch need to be on?

No. Twilight controls all the lights automatically as long as its not set to off.

oh, neat. ok. I'll give it a try.
so there's like a light sensor?

Yes, there is a little sensor on the dashboard vent.
