possible ignition switch? 1984 280se euro
 

I have a 1984 280se euro, it's really a 126 body model with the twin cam 6. It's like the 380se.

The car turns over when I put the key in and try to start...however it keeps turning even when I turn the key to off. It does stop when I pull the key out. Batt is new and does turn like it might start. Car usually starts no problem. Never had this happen before. I was thinking the switch. :confused:

Any help would be appreciated as always.

Can someone offer advise? Still does not start just turns
 

Just checking to see if anyone might offer assistance.
