I have 2 2821 routers set up for hardware failover. The only part I currently have to do manually is physically moving the E1 RJ45 cable for the ISDN30 lines over from one router to the other when a hardware failure occurs.
Will the E1 circuit still work if plugged into a switch (to allow me to split it and plug it in both switches at once)?

No, it will not work since E1 is a TDM circuit. The only failover you can do, is using manual failover as you do today.

Thank you for the reply
I'm not sure that you *can't* use a Y cable between your routers for your E1 tail circuit. See e.g.
You would need to make sure that the E1 controller on the backup router is shut down.
