Pros:
Decent search results.
Decent search frequency.
Cons:
The .info doesn't really fit the domain.
Would be hard to monetize well.
Many of the results and searches are for a band (Killswitch Engage) and a video game (kill.switch).
The only real use I can think of is an informative site (or minisite) about kill switches. Even if that were put up, there could be TM issues if contextual ads such as AdSense were used.
Appraisal:
$x, possibly a little profit over the $0.99 reg. fee.
