The switcher is a per caed audio card device placed between the sound
cards input and output (after the record decks and before the playout
audio is mixed in).

Description from docs/SWITCHERS.txt 
Driver Name: Local Audio Adapter

Supported RML Commands:
  Switch Take ('ST')
  Switch Add ('SA')
  Switch Remove ('SR')
  Switch Add with Gain ('SX')

It's possible to use one or more of the actual audio adapters as a
switcher device using this driver.  Doing so makes it possible to
route audio directly from the adapter inputs to outputs, while at the
same time using it for audio capture/playout in the usual manner.
