Yes backwards but I also change the default look on Halo, so who knows?
Not sure circuit breakers are a good example. In many panels, the breakers are mounted horizontally in two vertical columns. The on-off action of the left column is opposite the action of the right column.jcesare said:For example you wouldn't want a circuit breaker to turn on when you are repairing an outlet.
When I was in England in the late 70s, electrical switches are the reverse of what it is here in the U.S.: up is off, down is on. I don't know if it's still that way.jcesare said:As with most electroinc standards (switches come to mind), up is on, down is off.
I can believe this claim, though it'd be nice to see credible references.jcesare said:Years of safety studies have shown it's usually more dangerous to accidentally turn something on than turn something off and it's easier to drop something or lean on a switch and have it go down instead of up.
A major factor in human-machine interface is also familiarity with like concepts. Safety is important, so is familiarity.jcesare said:Most things has been designed a particular way and standards adopted for a reason. (Ever wonder why the hot water is on the left? Most people are right handed and it protects you from accidentally scalding yourself.) We might not always know the reason but there usually is some logic behind it.
The parking brake is "up for engaged" because that is how a hand-operated parking brake works in every car: pull up to engage. If it was reversed, I'd really be confused! Another reason for that behavior in the LEAF's case is because the parking brake "lever" is located where a "traditional" parking brake lever is located. If it was a push switch on the dash, then I would agree that "push to engage" makes sense.DeaneG said:My favorite backwards control is the e-brake flapper? Pull on it to engage - why not push like any other electronic control. Pulling a lever to activate something is so 1903.
Though I dare say, if one drives with a "loose puppy in the front seat", one has a few other things to be concerned about! One wouldn't drive with a "loose baby in the front seat"; why drive with a loose puppy?DeaneG said:Edit: figured it out - so the loose puppy in the front seat won't step on the e-brake control and launch the car into a tailslide.
True story: Yesterday while we were on the freeway my wife forgot and pulled up on the e-brake lever while trying to open the console storage space. Red lights flashed on the dash, and the car "stalled", i.e. acted as if I had taken my foot off the go-pedal, until she released the lever, then everything went back to normal. Actually, I was running on cruise control, so it was as if I had hit the Cancel switch followed by the Resume switch. Definitely no skid marks or loss of control. Did she push the lever down to cancel the brake? I guess anything is possible, but I seriously doubt it.DeaneG said:Edit: figured it out - so the loose puppy in the front seat won't step on the e-brake control and launch the car into a tailslide.

I believe the UK, Australia and New Zealand are still that way.aqn said:When I was in England in the late 70s, electrical switches are the reverse of what it is here in the U.S.: up is off, down is on.

If a switch is mounted upside down it says "NO" instead of "ON".jcesare said:In the US, the National Electrical Code states: Mount switches such that gravity won't close them. That means "OFF" is down and "ON" is up.
TEG said:It doesn't take me long to get used to arbitrary controls.
Besides, there is a precedent / history of auto trans cars having reverse forward, and drive backwards...
harrier said:I think it would be more intuitive to go forward to drive, back to park, and push a button and pull left for reverse. Or pull back to go in gear and forward to go into park.
jcesare said:I think the inspiration for the console mounted automatic shift came from the airline industry. In the 50's jets and rockets were the rage (fins on everything) and this control is similar to aircraft thrust controls. You pull back for thust.
TomT said:Nope, you push forward for more thrust on a jet just as you push forward for more throttle on a piston airplane.
