[GreenKeys] What the heck is a "Selector Key"?

[Derek Cohn/WB0TUA]

Hi Gang,

I picked up a box of "teletype" parts recently and inside were two NOS boxes.  One was marked "Selector Key 60A" and the other was marked "Selector Key 60C".  The boxes are dated May 1957.  I've posted photos on the web to help with the ID:

Here is the selector 60A:

Here is the selector 60C....it includes an envelope with some little part in it (I haven't opened the envelope):

I was planning on tossing both of these on eBay...if anyone on the list is interested in these, please let me know.

73 and thanks for any help you guys can give me,
