The Liberux NEXX will include 3 physical kill-switches for total privacy:
Microphone + Cameras
Wi-Fi + Bluetooth
Communications Module 
OFF → all other sensors are also disabled
This was the original design… but we're now considering the possibility of one more switch: 
, a slider integrated into the camera’s shutter button, to separate cameras and microphone. What do you think about it?
@Liberux The idea of a shutter for cameras should be a standard. Even if you have a kill switch engaged, someone nearby may think you are filming them, but if the lenses are covered, maybe less likely.
@Liberux Yes. Can be good to be able to use cameras while mic is off. But nothing really mandatory IMHO.
The more flexible the better, go with 4
@Liberux It sounds good but it also sounds like even more work. If it doesn't impact the time schedule too much I think no one would mind for more flexibility but I think it is not really that necessary to implement
@Liberux the camera and microphone definitely need to be separate.
@Liberux What does "Communication Module" cover?
@fabrice The Communication Module covers mobile data, calls, and GPS. Turning it off ensures complete disconnection from networks and location services. Let us know if you have any other questions! 
@Liberux So not wifi & bluetooth?
@fabrice That's correct! Wi-Fi and Bluetooth are covered by Kill Switch 2, while the Communication Module (Kill Switch 3) handles mobile data, calls, and GPS. This way, you have precise control over each connectivity feature.
Instead of adding yet another switch, an idea is could also make the microphone+camera switch have three states instead of two:
- microphone/camera on
- microphone on
- all off
@Liberux IMO if it doesn't complicate the design too much, sure, go for it. Otherwise I'm not sure it would be that useful, at least in my case as I would always have the mic + cameras switch off, except when receiving a call.
@Liberux I think that one physical kill-switce (1 - Microphone + Cameras) is enough at all. For 1 or 2 or 1+2+3 we can remove the battery.
@Liberux Sorry! For 2 or 3 or 1+2+3 we can remove the battery.
@Liberux as sensors can be used as microphone, I would say (camera + microphone + other sensors = a single switch), because I don't think we use those sensors often, so not a good idea to keep them lurking on all the time.
@Liberux Currently, kill switches on phones aren't necessary to me. But if they were, I'd gravitate toward one kill switch for camera and light sensor, one for microphone, and one for all connectivity.
That way, all possible picture taking would be under one, all audio recording under another, and all location tracking and remote access under the third. I could flip one to take pictures, and one to record audio, and one to connect to the internet or to text. Two for videos and two to call.
" OFF → all other sensors are also disabled"
@Liberux by sensors you mean gyro and also GPS?
@maryjane When you turn off , not only the communication module is disabled, but also GPS. When you turn off + + , the gyroscope, accelerometer, and other sensors are also turned off. Feel free to ask if you have any more questions!
@Liberux also imo it makes sense to separate camera and microphone, you might want to be able to get or place a call, but not have the camera enabled.
@Liberux "disabled" instead of "disconnected" could lead to the impression that the buttons trigger some software instead of a physical disconnection of components from the rest of the hardware.
I bring this up cause one other manufacturer of a phone with privacy switches kind of implied that there are phones advertised with killswitches that don't really do the disconnection of components... However, I'm myself not aware of any.
@derberg Thanks for the point. Yes, kill-switches disconnect the component by cutting the current in the circuit.
