3 lever light switch M-series

[johan77]

Hi guys, just found out why non of my lights are working, already had an idea in the direction of the 3 lever switch because the unloch lever didn't flipped back and the service lights lever was stuck , so i took it out to replace with a working one (wanted to make sure there is no shortcut in it before installing my new expensive alternator and ruin it) when i heard pieces rattling inside...never seen a model like this one, i assume it is an early one, it can open , has a large spring on the back, all other models i've seen are sealed. so i probably can rebuild this one if i only knew what goes where. the only thing i dont know is about the brass parts, wich one goes where on the black plastic carriers because there are brass parts with 3 and 2 contact tips on it.
Thanks guys !!
