Hi folks,

I would like to replace the odrinary toggle power switch of power (220V) into a Bulgin Illuminated Vandal Resistant push button, just like the one which was used in krmathis' beta 22 here. Would anyone let me know how to do that?

Thanks

amb knows how

Thanks cobaltmute, but simply abm does not provide full kit for the ε24 Power Switch Driver Circuit but only blank circuit boards .

Good one

You have posted this to the DIY forum BTW. Amb provides a BoM & all sorts of other info so just order it up & away you go....

One little thing, if your A/C or little 12v transfo is a bit shakey you might need to raise C1 - 470uf cap (2X -> 4X) to help it stay latched during transients (I did).

Nice design that ε24...

Oh good god... this is the DIY section after all

The switch used in "krmathis' beta 22" was a latching switch not a momentary switch.
If the current draw of the device is more then a couple of amps you may also need a relay.

There are a couple of other links in AMB's e24 thread at Headwise.
Other designs used to arrive at the e24's final design.
Also, performancepc.com has the same looking push button in black, Delrin I think(hard plastic).
No kits that I am aware of.

Thanks all for the info, I will sorting out sometimes later this week and with a try.

Thanks again.

Thanks MisterX, that's what I exactly wanted

, no complicated circuit needed, just replace the button.

Indeed!

When I looked up the two switches listed above I am pretty sure they show up as momentary.

Are all the Bulgin switches momentary or do they make a true self contained "latching" type?

I like the look of the Bulgin switches a lot but did not want to add additional circuitry to my project.

Thanks!

As far as I know there aren't any switches like you describe that would take the place of a traditional power switch.

The switch listed here is latching, blue 12V LED.

D'oh, I'd forgotten about those.
