Alright, so some of you may know from this thread (http://www.hard-light.net/forums/index.php?topic=68967.0) that I'm doing a web app for a CS project. For those noob losers too lazy to read the thread, it's basically a rudimentary Facebook app.
I'm going to have button controls for 'login', 'logout', etc, each with text and an icon: an electrical symbol. There's no definite metaphor going on, but there's an obvious pattern so I'll give some examples:
Login & View Own Profile(when viewing someone else's) = battery
Create new user = AC power
Logout = ground
Add User As Friend(when viewing someone else's profile) = resistor
Find User = ohmmeter
Edit Profile = switch
Save (in Edit Profile dialog) = crossing wires, connected
Cancel (in Edit Profile dialog) = crossing wires, not connected
I still need icons for Upload File and Download File (which I'm about to implement). What would be good symbols to use for those? They have to be relatively simplistic, as I'm putting them on 32x16 images so they can go right above/beside the text.

Perhaps you could use the inductor/transformer as the upload command, where the corrolation there is that you're transferring something, in this instance, data.
The diode would be a good icon for downloads, where the corrolation is that a signal flows in only one direction, in this case, to the downloader.
Just my thought on the matter.
:D
-
I might use those. I dunno.
Any more ideas?

electric line truck as moderator/admins would be humorous.

upload download: LED and photosensitive diode respectively

aaaand, apparently those are black lines on transparent, hence the quote

solenoid? there's also something my senior design group has used called a spark-gap switch. we think that may be an innovation by one of our professors, as no one had ever heard of it before, and he was quite excited to get to use it. give me a bit to get the icon for it. i'll probably have to draw it in paint real quick
here we are

This (http://library.thinkquest.org/10784/circuit_symbols.html) might be a good resource for you to use. Although, as an EE, there is no symbol for an ohmmeter, as it can't be attached to a circuit.
-
Hippo: Those look good. That's probably what I'll use. I may need some more symbols though for other stuff- I dunno yet.
Klaustrophobia: I'll keep both of those in mind.
Tyrian: really? A lot of the sources I've found use an omega in a circle, like the other 'meters. Is it nonstandard?

Thanks everyone :)
-
it isn't supposed to go directly in the circuit path, but attached by a line.

The V and A in a circle are semi-standard. I've never seen the omega in a circle, again, as ohmmeters cannot be attached directly to a circuit. If you do attach one to a circuit that has power, your meter will just give you an error message. If you attach one to a circuit with no power, you won't get a correct reading.
[MassiveGeekOut]The reason for this is that an ohmmeter applies a precise current to a component. It then detects the corresponding voltage across the probes and then calculates resistance via Ohm's Law. If you attach an ohmmeter to an active circuit, then the division circuit gets confused. If you attach it to an inactive circuit, you end up measuring the Thevenin resistance of the circuit in parallel with the load resistance, which is a quantity that doesn't exist in the real world.[/MassiveGeekOut]
