The Kindle official case for the Paperwhite model features an automatic off switch when the case flap is closed and auto on switch when you open the case.
How is that achieved as there is no physical switch visible ?
I checked and found that there is a magnetic clasp on the flap of the case
opposite an embedded metal strip (non magnetic) in the edge ot the case. These are obviously there to keep the flap closed as well as activating the magnetic sensor.
My question is :- will the magnetic clasp, on its own, activate the sensor without the metal strip ?
