I think the rocker switches as seen on the KA10 and PDP-12 are slide switches with a rocker mechanism mounted on top. But the PDP11 switches are mini toggle switches as far as I remember; the only change is what sort of handle was slipped over the toggle. Yes, the 11/40 and 11/45, for one; the 11/20 also.
