I have several pins that I want to send to ground individually via DIP switches. Rather than wiring each switch to ground, I want to run just one wire to switches that are tied together internally. (see attached diagram).
I've seen resistor arrays that essentially do the same thing, but cannot find where this is done with DIP switches.

@jackrae, rather then placing annoying " " around a link (which makes it even harder to select), place [url] [/url]

@spkepler, why can't you simply connect all those pins together yourself? Warming up the iron takes the longest when soldering them together...
The term you want is "bussed", and a cursory search of Digikey suggests bussed switch arrays don't exist.
I'm with septillion, add the bus connection yourself.
Digikey offers a bunch of DIP switches, here are x8 versions, none have a common pin that I can see.

assuming you are using a breadboard why not plug one of those resistor arrays next to it to achieve the same thing.
edit
they are available in zero ohm variants.
Or if you have a breadboard where the common bars line up with the rows, just put on end in the common bar
