Indeed it happened more than once that a professional pilot, even without too much stress in on the flight deck, pulled the wrong levers, switched off an engine instead of setting flaps or pushed the wrong button.

I seem to remember someone landed an A320 with the park brake set due to a control mix up , anyone remember it? I also vaguely remember that it had happened a few times despite there being no similar control on the flight deck.

The only incident that springs to mind was the crew that thought they'd have to land with the park brake set after fiddling with the lever in flight. I doubt it was a control mix up as there's nothing else down there that you would operate in normal flight.

Going back to the original question I noticed yesterday that out 744s have similar landing light switched with three bumps, but they are only 2 position switches.

I had a little read Carnage, it was a BMI A319. Commander selected park brake on instead of moving the flaps.

Anyway, back on topic

Blimey! Wrong location, wrong lever, wrong shape, wrong movement (lift and rotate rather than lift and translate). Must have been having a bad day!

SO do we have a definite answer to this question? 3 bumps on the landing light switches? same switches in Boeing and Airbus, not sure about the Dc9.

Anyone ever set the A320s park brake during push back instead of turning the start switch on ? They're not too far apart and the actions are similar.

The only dumb question is the question not asked.

this was discussed (and, unusually, the answer proven with some photos) a little while ago. The cross marks the point at which that panel's integrated lighting is powered.

Sure it was an A320...? Not familiar with that type but certainly there have been incidents with the Embraer E170 and parking brake vs spoilers (Finnair for one)..

Jepps are printed on rice paper with soy based ink. Done that way for survival use.

Slowing at the end of pushback, so no damage.
I assume the towbar shearpin did its thing!

A320 Landing Light switch, from what I recall, 3 position switch for each wing landing lamp, OFF, EXTEND (Lamp Unit extends from recess in Wing but remains extinguished) ON. Nose Landing lamp is a 2 postion switch, ON, OFF. Two Taxi lamps on NLG, associated switch is ON, OFF.

As for the 3 dots on the switches......French Logic......

The design of the large flat horizontal surface lever action type switch/s which by way of shape/looks has 3 small protrusions to make for a positive tactile feeling (& built like that for strength) are so made as to be placed in whatever position is required without the chance or at least reducing the chance of the fingers slipping off as might be expetced with a normal toggle type switch. These switches can be moved over a fairly large arc of travel across a detent (center possy) as opposed to a simple on/off switch. As apposed to the T.O/Taxi switch which is also a 3 possy switch which is normally only moved one segment at a time, this is a std type of toggle switch. Remember these two switches are normally turned off or on simultaneously and their very shape by design almost makes then act in the same manor when switched together as though a 'ganged' type switch
Also note that pretty much all other reg used 3 possy switches (ext & Int) have also flat or larger surface area lever action toggles as they can be moved thru two possies in one action:-)
Who dreams all this sh1t up?
Anyone???:-)
Anyway just a theory

Wmk2 way out on a limb here but my mum reckons it sounds good

Braille

3 dots in the Braille system is the letter "L" (maybe Light/Landing Light?)

Yep, there's no reason blind pilots couldn't fly an airbus!

Perhaps, but why would a blind Airbus pilot need to switch on the landing lights
