‘49 3600 261 SM420 12v Swapping out my generic Napa key switch while installing matched lock sets for everything. Using the repro key switch with the included light housing not the separate bracket. Switch is unlabeled on the terminals but bottom terminal works like the battery terminal and 1 click CW connects all three terminals (so I guess you could put the battery wire on any of the 3 terminals by itself). The key still clicks once more to the right which is also all off and the key won’t come out. So: full CCW is off, 1 click right is all on and 2 clicks right is all off but key stays in. No apparent distinction between ACC or Ignition for the terminals.
Do I have a mismatched key/ignition switch body? Like a three position tumbler in a two position body? Pics below:
