    I hope you don't mind me asking, but why do you want one? There's a huge number available; hundreds.

    How could I resist a chance to show off my 1337 ASCII art skillz?

    Code:
        /
--o/  o--   SPST (2 terminals)


    /o-- 
--o/        SPDT (3 terminals)
     o--
   
   
    / 
--o// o--
--o/  o--   DPST (4 terminals)

    /o--
--o//o--
--o/        DPDT (6 terminals)
     o--
     o--
    SPST means single-pole, single-throw.
    DPDT means double-pole, double-throw.
    (I'll let you work out the other combinations on your own.)

    Then you've got the rotary ones, which can be from 1-pole 12-way to 4-pole 3-way.

    I'll let linear draw them... :p

    It's a change-over switch, so you could have a 7v and a 12v in, and switch between for the out.

    You also find them top & bottom of the stairs, so switching either will turn the stairs light on or off. Domestic lighting ones sold in the UK as "intermediate" switches.

    Some dual light switched also use XOR gates apparently. So you have two on/off switched as normal, connected to the inputs of an XOR, then the output connected to the light (well, a relay then the light).

    No, it's Double Pole, Single Throw. That's means you can have two sets of on/off.

    Code:
        / 
--o// o--
--o/  o--
    Stealing linear's ASCII there ;)

    Some you can, but this one doesn't specify one, so I'd assume no.
