Anybody know the size spacing of the 3pdt switch pins? (Darron?)

[rockgardenlove]

I know Darron made some really cool boards that mounted straight onto the switch-I wanted to take a shot at this myself, but I don't have a switch handy to measure.  Anybody have the pin spacing of maybe even a graphic already?

Thanks!

Let me take a shot in the dark here......
If you're using Bancika's software I would have to say 3 pads X 3 pads maybe?

I actually just bought a digital caliper for this same reason. I don't know if I'll have time to measure them tonight, but I plan on getting the measurements before this weekend.

I know, I'm not much help

Hey,

The pins are on .2" spacing. I set my graphics program for a .2 grid and laid it out accordingly. When I drilled it, it fit perfectly.....I forgot the drill size I used... might have been 1/8... when I get home from vacation, I'll check to make sure.....

Also of note is that it is .2 either which way you turn it.....

Hope this helps,

Mick

i feel special. i usually deal with everything in mm, being from australia. my suggestion if you are doing pcb mount (which is a really practical way!) is to get it tight enough so that you really have to wedge the switch in hard. that is, strong enough so that without solder it should be able to support itself quite firmly. this way it abolishes my fears of it possibly ripping the copper traces off the board. i doubt that it would be at all easy for that to happen. when you are done you'll get a satisfied feeling that you've created something really sturdy and it feels really clean (not messy?).

anyway, i guess to avoid confusion i'll make up a little diagram:



the measurements may not be perfect, but they are what i use and they end up working really well. what software are you using? i could export the actual component template i made as a pdf, eps, or a bitmap file (with correct dpi that you are using) like png, jpeg if you could intergrate it.

i was thinking of designing a printable pdf file with a circuit board which handles all the fiddely wiring. this would include:
- led wiring plus limiting resistor
- grounded effect input on bypass
- single switch bypassing (i discussed in a different thread)
- 1m / 2m2 static discharge resistor allowance?
- maybe geofex style capacitor LED ramp up allowance. i'd only we worried about polarity protection on this one though so maybe leave it out. also people would need a jumped if they wanted to not use ot

do you think this would be useful for some people in the diy community?

Yes, it would...

I for one would really like something like this...

there's this: link but it doesn't have allowance for pull down resistors or an LED limiter. i'm trying to think of a nice and neat way to design mine now.

I print mine right now right from Bancika's layout software.  Not very integrate-able.  I really just need some better software; I have Photoshop on my Mac, but not on my PC, which has my laser printer.

PCB mounted jacks would be nice too...

yeah. i don't think that would work then? illustrator is better for working with vectors than photoshop, but you can use that if you want to take the hand designed approach (:

here's how you print from photoshop on a mac to a pc's printer: make a quick image to test and do the print with preview option in the file menu. make sure that your image isn't set to size down and that the dimensions are correct. confirm this. when you come to the final printing window there's an options to SAVE AS PDF! very useful feature that works in most programs on a mac! i'm using OS 10.4.9 and i'm not sure how far this feature goes back?

anyway... get the pdf onto the pc somehow and use acrobat (even in internet explorer) and it will print it exactly as the mac would have. do this the same way as tonepad etc. (:
