There is a faster way to switch keyboards.
In the Android 4.2 Keyboard settings, go into "Advanced settings" at the bottom of the page (see the first attached screengrab), and check "Switch to other input methods" (the second attached screengrab).
Now, whenever the Android 4.2 keyboard is up, you can long-press the globe key to the left of the spacebar, and you'll get the "Choose input method" pop-up.
To me, this is faster than pulling down the notification shade and choosing from the pop-up.
