Schematic symbols?

I found this schematic in a 1947 manual on vacuum systems and I cant translate the indicated DPDT switch into something I understand. Can anyone sketch a quick pinout for it, preferably indicating what goes where on the schematic. This goes along with my other pirani gauge question.

Hi everyone !, I would like to know what kind of symbol configuration most of engineers or pcb designers use or what standards follow to create the symbols.I found some recommendations and i have two examples of symbol configurations , In the "Image #1" i created the symbol placing inputs and pasive pins on left side and outputs on the right side and in the "Image #2" i followed the symbol configuration of the typical application of the datasheet.Which of the two configurations is preferred or recommended to use and why?Thank you.

Symbols in Word 2003 and up? Answered

Used to have word '2000'. It was easy to allocate symbols, like 'degree', (small circle in uppercase). I used to allocate D for this symbol. Now I have a newer version (2003, really HATED the Word 'Vista' version...)!  But it seems hard to allocate any shortcuts for symbols now... People, please tell me how to do it..., otherwise I will delete it (again...). The 2003 Office Suite, to be replaced by the decade old ' Office' version??? Please don't tell me the buggy old 'open office' is better... Just put it on your USB stick...

How do I put labels in a front panel?

I have made a multiconnections box for my computer that fits in a 5-1/4 bay. It has four USB ports, 1 Firewire, mic and earphones and several card readers. The front panel of the box is made of plastic and painted with spray paint to cover putty patches. I want to put logos for every connector, the USB logo, the Firewire logo, a logo of a mic, a logo of an earphone and the identification of each card slot (CF, SD, MS, etc) What are the ways of doing it with a factory-like finish? ¿custom decals? ¿Screen prints? ¿Is there any instructable about the matter?

What math process is indicated by a symbol of an integral with a circle drawn at near the center of the integral symbol? Answered

I believe that this is has something to do with physics, possibly calculations pertaining to WORK. I know what an integral is but I am not sure what this is telling me to do. Derive an integral in some fashion other than standard? As I said above the symbol is a standard integral symbol from calculus except there is a circle at the center of the symbol.

Symbol CS1504 Keychain Barcode Memory Scanner

A couple of years ago at work I purchased this little keyring barcode reader It's a great little thing. It comes with no software so I paid to download some reading software (don't know what I did with it) which had fairly limited functionality it would show me the date and time of reading, the type of barcode format and the barcode number. What I really want to do with this now is use it for asset checking. I want to put a barcode on every door in my building and an asset number barcode on every asset. That way when the yearly audit comes round I can nip from room to room and scan the door and then all the assets. Come back to a PC and download - Room ID, Asset ID and a date and time stamp. But what I really want this to do is to just pull the description data associated with the asset number from so sort of table. The developer software is freely available... but I don't want to learn Pearl or any other language just for this... If someone made a little open source app... I'd pay for it (as long as it was like the budgy) If you could compile a little app for the Symbol how cool it would be!

Wall wart for digital camera

Hi everyone, I have a cheapo digital camera, a Norcent DC-1020. I've been trying so hard to figure out what kind of wall wart I need for it. It's rated at 3.3V and 2A, but here's what's confusing me, at the input it says "DCIN3.3V," which makes me think it needs a DC wall wart, but the sticker on the bottom says "3.3V [symbol] 2.0A max" where the symbol is two lines, one solid, one dashed. I thought that symbol was for AC?

Zombie Costume Question

I am working on a soldier zombie costume, but people keep telling me that I look like a nazi soldier. They have me worried that my costume will be in bad taste, but I am not so sure as there are no actual nazi symbols on my costume. Should I risk looking like a nazi or should I try to distance myself from that? If you think I should distance myself from that, how would you recommend doing that? Some have suggested that I embrace it and wear a red armband, but with a mocking symbol, like a smiley-face or a peace symbol, a sort of mild satire.
