In the book 'We Seven" there is a chapter entitled "Seven miles of wire and a Swizzle stick." The swizzle stick was a short length of - well stick - that was supposed to enable the astronaut to reach switches when under 'g' loads.

Was it ever used or even carried on any Mercury flight? If carried and not used, does it qualify as the most useless piece of equipment carried on a spaceflight?

Yes, the swizzle stick was carried onboard. Here's a photo of Sigma 7's swizzle stick.

I don't know if it was ever used. If not, it was only as useless as, say, the reserve parachute, since it was never used either.

The reach aid, or "swizzle stick" was still in use during the shuttle program, too, and came in quite handy (no pun intended). A similar device is used aboard the Soyuz.

The flight engineer, seated behind the commander and pilot on the flight deck, used the stick to flick switches out of reach from his seat.

The reach aid, sometimes known as the "swizzle stick," is a short adjustable bar with a multipurpose end effector that is used to actuate controls that are out of the reach of seated crew members. The reach aid is used to push in and pull out circuit breakers and move toggle switches. It may be used during any phase of flight, but is not recommended for use during ascent because of the attenuation and switch-cuing difficulties resulting from acceleration forces.

The Mercury swizzle stick must have been at least somewhat useful, as a swizzle stick was also used in the Gemini spacecraft (located on the right side of the Overhead Switch/Circuit Breaker panel). But as far as I know a swizzle stick was not used on Apollo.

Anyone have a good photo of the NASA swizzle stick, or Reach Aid?

Something a little bit more detailed than this:
