    Following davenn's advice to you, I followed that link.

    Then I typed in "rotary switch" and pressed enter.

    Then I was given a list of possible categories. I clicked on "rotary" in the "switches" category.

    The parametric display was shown.

    First I selected No of positions = 2, and clicked on Apply filters

    Then I clicked on Number of decks = 1 and clicked Apply filters. (I'm not sure exactly what decks are, but I assume it means layers of contacts, and you need only 1)

    I then select SPDT (because there's no SPST)

    I get a list of switches.

    Look at them one by one, reading the datasheets (which will have dimensions). There are a number of very close matches for what you want I think.

    Remember that if the shaft is too long you can cut it.

    SPDT will have 3 connections on the bottom. You can ignore the one you don't need.
