I'm struggling to understand which switch Hamilton turned by mistake.
That's the 2019 wheel (from this video https://www.youtube.com/watch?v=OX58IkeSl4c
I thought it was the one marked in the picture in this post (BBAL)
But looking at onboards this is a design used only by Bottas, Lewis supposedly uses this wheel:
They are identical apart from having different colours which is probably driver preference.
However if you look at onboard from Lewis in the last few races he used a different wheel
Different placement of buttons (N is moved for example) and different colours for the switches.
It's not the wheel shown on Mercedes' website where they explain how it works and what it does.
The colour scheme is the same however.
That's the text on the site, i added what i assume the switches are on the wheel
"Our 2019 steering wheel has a total of 25 buttons and switches and, of course, the clutch and the shift paddles. Five of those buttons and switches change the brake settings of the car: the driver can shift the brake balance from the front to the rear or vice versa [BBAL], to optimise the brake balance for an individual corner, change the amount of engine braking [EB] or adjust the brake migration [BMIG], which is a dynamic change of the brake balance depending on how hard the driver brakes.
Another three switches control the differential - the amount of torque transfer between the rear wheels - for the entry [ENTRY], the apex [MID] and the exit of a corner [HI SPEED?]. The rest of the buttons and switches have a variety of different purposes, from adjusting the settings of the Power Unit to changing the data that is displayed on the screen, activating the radio or the pit lane speed limiter."
I don't see any cover or "guard" as they said in the video anywhere near the EB switch unless the entire brown-ish piece went off.
