Got an easy question. Most of my dash switches work as down - on. This includes the head lamps, interior lamp, and emergency flashers. My heater fan switch works up is on. I may have assembled the switches wrong or installed them upside down. The icons seem orentated correctly and the wires are connected to terminals as listed on the Advanced Auto wiring diagrams. I want to get this right and it looks like the dash is coming back off due to problems with the speedo and rev counter.

So. Is up - on or is down - on.

Cheers,

Bob

Down is ON on my 66 MGB (even Down Under)smiling smiley. Not sure if it changed for later years or for the US market.

if you install a fuel pump switch, install it opposite of the others. Reason...it you leave the car, turn off fuel pump (it will look "on"winking smiley and thieves will not get a block away before they run out of gas. Of course, you don;t want to label it.

OK. So if down is on I'm mostly good. How about my heater fan switch? That one may be installed up side down. The icon for that one is the same if inverted. Should it also be down - on? That will be easy enough to turn around.

Cheers,

Bob

@Bob: FWIW, on both my cars, 76RD and 70GT, the fan blower switch is "on" when the paddle is down. Same thing for headlamp switch(es).

Lou,

That's it! I just need to turn the fan switch around. Thanks all.

Cheers,

Bob

the word FAN is not upside down when the switch is properly installed. So, unless you are using a non-fan specific "universal purpose" switch that has no label, the green insert goes at the top. Supposed to be a tiny light in there.

Down on was factory correct on my new 1971 MGB's switches. It always seemed strange when the NA standard is down is off and up is on.

Mac,

My switch is the original for 69 and has a fan icon that is symmetrical so it will be just fine when I turn it around.

Cheers,

Just to pick up on this old thread, if I may:

I'm reinstalling my dashboard - or, rather, a reconditioned one I swapped my old one for - and the heater switch only fits upside down (on is up) because the hole has a segment not removed to avoid the switch rotating. This prevents the switch from being installed right side up. This applies only to the heater switch.

What am I missing?

The correct switch. The one, that you have, is designed for a different application. RAY

In NA it is normal for switches to be on when up, off when down. Maybe it is done the opposite in the UK. Down is on, up is off.
For some reason the NA MGB is different than the NA electrical switch norm.

Switches in the UK are down when ON. The most common are the switches on the mains socket, which you see everywhere. MGB dash switches are no exception.

I believe the logic behind this is to be able to see the red label (or light) on top of the switch to warn you it is on, since switches are usually looked at from the top (when was the last time you had to turn a light switch mounted overhead??). Had it been at the bottom (like NA switches, for example), you won't be able to see it.
