Narrative:
I was climbing after takeoff to assigned altitude of 7000 ft. Departure control cleared me to FL190. He then gave me a change to stop at 10000 ft. I had originally set '70' in the altitude select window but changed it to '100.' what I didn't notice was the vn-212 altitude controller switch was pointed at the 'stael' instead of 'altitude.' this is very hard to see and I did not notice it had been moved. Therefore; the autoplt did not level at 10000 ft.

Narrative: I WAS CLBING AFTER TKOF TO ASSIGNED ALT OF 7000 FT. DEP CTL CLRED ME TO FL190. HE THEN GAVE ME A CHANGE TO STOP AT 10000 FT. I HAD ORIGINALLY SET '70' IN THE ALT SELECT WINDOW BUT CHANGED IT TO '100.' WHAT I DIDN'T NOTICE WAS THE VN-212 ALT CONTROLLER SWITCH WAS POINTED AT THE 'STAEL' INSTEAD OF 'ALT.' THIS IS VERY HARD TO SEE AND I DID NOT NOTICE IT HAD BEEN MOVED. THEREFORE; THE AUTOPLT DID NOT LEVEL AT 10000 FT.
