Thanks, thats good to know because I didn't order them yet. I was suspicious of the low price. $19.95 for three. I want to find a latching pushbutton that is rugged and has 100,000 or more cycles. Preferably soft spring style. ;-)

I picked up some of the Bulgin latched switches, and they were roughly $20 eah On the other hand they are electrically rated for 100,000 cycles minimum

The spring is soft indeed, but definitely not rated for 100,000 cycles. On the other hand, they're so cheap and are sold in triplets. It won't hurt to use them. Just be prepared to install a new one after a year or so.

There's also some that are illuminated. They're a great way to combine LED and switch.

Those look really nice, like a led ring version of the one I got. Wonder if there's a stateside source for them

Yeah, really nice.

Last picture was my own switch that hasn't been installed yet, but I was thinking of making this circuit:
Soft Switch

And on that site you can se how it looks when it's "on"


Cheers

That's the only part that I'm not too thrilled about. The need for a relay based backend to use the momentary push button convinced me to pick up the latching push button. On the other hand, that soft switch pcb looks very convenient. I wonder how much does it cost to get pcb's made up.

Here is the mouser part number for a Bulgin 18mm blue ring illuminated latching switch in stainless steel for $13.90
I have one coming in 2 days along with a neutrik phone plug. The only drawback being 18mm, which is not as large as I wanted. But it's good for 200,000 mechanical cycles and 30,000 electrical cycles. This means that it will turn the circuit on and off 30,000 times and then you can push the button 170,000 times if you want after it stops working. he he ;-)

Have 100% of the parts on their way. Sprayed my Cocobolo sides with shellac. 3 coats of the Shellac. Tommorrow, 3 coats of Cellulose Lacquer. This is a hard and mirror shiny finish when done. Cocobolo is an oily wood therefore always spray Shellac before Lacquer to get good adhesion.

<-- drooling.

Coolness, amphead. And a woodworkers education tonight to boot. Thanks!

I've been working on getting Alien dac parts and have stupidly neglected my kit. What am I thinking?

Thanks Bhjazz, are you trying to get the Bijou done in time for the Seattle meet? That should get a good turnout. If I could swing it, I would visit family there and go to the show, but alas it just is not in the cards. ;-)

Absolutely Nebby, I will be posting right after buffing out the Lacquer coat, even before mounting more parts. Thanks
