Can I use the wall switch with a device that has a digital power switch?

If you plug your television into a wall switch and turn the wall switch OFF, it will remove power from the television, turning it OFF in the process. If you try to turn your television ON with its remote control, it will not turn ON as it has no power going to it. When you turn the wall switch ON, it supplies power back to your television, which will then go into standby. You will need to use its remote control to turn it back ON.
