What is this symbol

A relay or maybe a resettable fuse or maybe even a crystal.

Or maybe it is a quantum device. ;-)

It looks like the coil (solenoid) segment of a relay.

Symmetrical zener, aka surge suppressor or MOV? ...Jim Thompson

nonstandard, so it could be anything. Most likely a relay coil.

Are we looking at the same image? How can that be a coil? ...Jim Thompson

Probably bi-directional clamp.

Real simple. Go to Google. Select google images. Enter "relay schematic sysmbol" as the search script.

Look through the images that appear and see that there are SEVERAL similar symbols used to describe the energization coil of a relay. Yes... looking at the same image.

There is a chance that it is a snubber, but those already have a symbol and that ain't it.

You could say the same of many supposedly standard circuit symbols. It certainly looks very like what I've seen used as a relay coil a fair few times. As for why they'd use a box with a schmitt/zener like thing, who knows.

NT

Maybe it is meant to show that it is a DC pulse that drives it. It looks like a small square waveform.

It could be an integrated relay coil *with* a snubber in one unit, described by a single device sysmbol.

IEC symbol E1215, "Relay coil of an impulse, sequence relay".

See at the end of page 23 here:

It seems to be used for coils of latching relays, unless the relay is mechanically (rather than magnetically) latched. Mechanically latched relay coil symbol is E1214.

Yeah, MOV maybe. OR, with the A1 A2 designations, might be some other representation of a diac ?

Ga-a-a-a-ack! IEC/IEEE symbols are the pits :-( ...Jim Thompson

Ahhh... Las Vegas casino sign light array cascade relays! (or something like that).

More like the epitome.

Unlike you.

Yup. And there are some fool enough to think I should use them.

Hey I've got a symbol question. (I'm only responding to you 'cause you're the last post.) I was reading the filter section (chap 6.) in AoE3 and they have an inductor with a little rectangle with arrow over the inductor. Is this meant to show a slug tuned inductor? (see figure 6.6 pg 394)

George H

Yes - it is. The idea is to be able to adjust the excact frequency out of the filter.
