Sunvsior micro switch replacement

My passenger side sun visor intermittently does not trigger the light bulb in the headliner. I have checked the connection via multi meter and seems the micro switch behind the vanity mirror is malfunctioning. It gets 12V. If I jiggle the switch button a bit the light comes on. Does any one have a link to a place I can order that part? Thanks.

For reference the switch looks similar to the blue one shown here: http://www.benzworld.org/forums/3369613-post23.html. The difference is my switch's poles are on the 2 ends (i.e. the middle pole does not exist). I think this is possibly due to my switch operating as closed when the plunger/button is up and open when the plunger/button is down. I think the one shown operates in reverse but not sure.

Anyhow, any direction/help is appreciated.

I can't attach pictures, but in my visor the cassette (with the mirror) hinges have no connection with the switch itself. I am fairly confident the switch is the bad element. We'll see. The only thing is that the existing switch is a "Normally Closed" version (SPST-NC; Single Pole Single Throw Normal Closed). I don't think the manufacturer makes that model anymore. They only make the 1500.0202 model I listed which has an extra pin (SPDT; Single Pole Double Throw) in the middle. I will have to cut the pin or break the housing in the cassette a bit to make it all work. Anyhow, the order is in. Not sure when I'll get the order but I'll post progress.
