Hi Rachel,
Which switcher is this - Carbonite or Acuity?
If it is Acuity, you can accomplish this with CC Logic. The Acuity will check if the keyers are on/off, and based on the keyers' state, it will perform the programmed actions.
However, if it is Carbonite, there isn't an internal logic system like Acuity. But you can use DashBoard to run the logic. So when a CC button is pushed, the Carbonite will trigger a custom DashBoard panel to check its keyers' state, and DashBoard will tell the Carbonite to do the corresponding actions.
