Yet another resistance decade box

High-quality hot snot. Infinitely configurable.

Never seen them myself, are these 'KM2' switches actually a knockoff of another manufacturers part?
The only time I've ever used these dirt cheap far eastern sourced switches they were wrapped in black insulation tape and not even fitted to a panel. :D

for a midnight build, if a deadline is tomorrow - yes.
for a real build, I'd prefer to find something that was clean enough so that you are proud enough of the insides that you'd build it with a clear front (or all clear) panel.
also, glue is less repairable; meaning that if I needed to pull things apart and clean contacts or fix things, I don't want to deal with a previous glue job.
btw, my set of switches from ebay is due for delivery today. I'll give mine a look and see if there is a non-glue (lol) solution to mount this acceptably.
I don't have the boards yet, but I'll see if I can do a dry fit into some plastic lasercut box and see how it goes. when I get laser time, I'll make something and post an update.
bitseeker:
Yeah, I was being facetious on the hot snot. Looking forward to your impressions on the switches you receive.

I use plenty of hotmelt glue, but only on things that I don't plan to show to anyone or things that are temporary.
perfect use-case: some diy perf board with standoffs; and I'm still working on it and need some chassis just to hold the jacks up. I'll hotmelt the alum or nylon standoffs to the chassis (pcb is screwed to the standoffs, first) and that will let me try out a wiring config or routing. I might change a few more things over time before I want to commit to an expensive metal chassis (that someone else makes, at high cost to me). I can pull up hotmelted riser posts easily, yet they stay down long as I need them to, to run test wires to. as long as I don't ship it, I can even bring temp work to demo events and shows. you'd never have a clear cover over such things, though ;)
the procedure is quick, too; with the pcb screwed to 4 alum/etc posts, dab some hotmelt quickly on the screw areas of the bottom posts and quickly position to the plastic base/box. it sets in under a minute. requires just hand force to pull up when you are ready to change a config or try some other board in that place.
anyway, I'd like to see something that is held down by screws or a pressure plate that pushes something against the front panel, so that its undo-able, for future service.
if people have ideas, post them! this is not my specialty, so if others have better ideas, lets hear them.
