As, delivered by Santa, in the early 1950's, a Lionel #455 Oil Derrick, all original, with all of the original goodies and all complete.
My unit has a black bake-lite, two position('On/Off'), slide switch, with: "Lionel Control Switch" molded on the front cover of the switch case, and in white paint, printed on the back of the switch is: "364C", even on the instruction sheet and the envelope, the switch came in, refers to the 364C switch, if you must have an original one.
Olsen's Toy Train Parts-Library-shows five pages from a Lionel repair and operating manual and has listed under: "Part No.--364C-1", on the last, or page 5, of five pages.
Now, for some confusion; On the "Lionel Postwar Library" web.site, they mention a "#96C Controller", which may also be used and has a black bake-lite case.
The aforementioned switches and there are other switches which can be used, whether slide, spring tensioned, or whatever, such as a direct hook-up to a transformer.
