I'm running iOS 12.1 on an iPad Air.
Regardless of the switch setting (mute or rotatation) the side switch does not control screen rotation. There is no rotation control icon available to select under control centre. There is NO rotation control.
What do I need to do in order to control screen rotation on my iPad?
Since you've restored the iPad I would say that you've got some issue with the Hardware. If possible, Take it to an Apple Store for a Hardware test.
Using an app which requires the use of the Accelerometer may test it too.
EDITED: Its not the Gyroscope what tells the position of the device but the Accelerometer.
You could try a custom action using Activator, set up to toggle WiFi when the Silent switch is double-toggled.
I am currently not jailbroken myself (running iOS 7) and haven't used Activator for a while, but I remember that there is an option to activate an action by double-toggling the mute switch, as can be seen in the screenshot below.
There may be a way to activate it using a single toggle, but I am not able to find this out myself right now. Despite this, a double-toggle returns the toggle to its original point, meaning that you could use the toggle for WiFi and orientation/mute at the same time (a single toggle doesn't activate the double-toggle action).

There was no “Rotation” control icon in the control center. Reboot, and it “Automagically” appeared for the first time... EVER.!?? Forget the switch... this control will suffice. Thanks for trying to help! ~fss
