WIPO Patent Application WO/2021/035518
Kind Code:
A1
Abstract:
Example switching circuits are described. An example electronic device includes a switching circuit comprising a switch to be mechanically activated by an activation device to generate a first signal. The switching circuit further includes a magnetic field sensor provided adjacent to the switch, to generate a second signal in response to sensing a magnetic field. The electronic device may operate in a first mode, in response to receiving the first signal in absence of the second signal. The electronic device may further operate in a second mode in response to receiving the first signal and the second signal.
