Hi friends
I'm—again—struggling with details and aesthetics. This time it's the switch.
Bathing in the sea of variations @ mouser, Distrelec etc., but there's nothing I really like.
I'll probably end up with a switch without "frontend"—requiring a self-made toggle of sorts, but still haven't decided on the function: Push-button, rocker-switch, rotary?
My fantasies are:
- Oversized "long stroke" pushbutton — inexistent?
- Rockerswitch: making a part of the frontplate the switch...
- rotary: Is there a switch that triggers 90°, that could be rotated endlessly? (not back and forth, but on-off-on-off-on etc. in one direction...
Could I get some directions, parts, techniques?
many thanks!
david

You will have more options if switching low level and using a relay for the power.
microprocessor or logic circuit also gives more options - how about a proximity sensor?
3D print or fabricate your front plate & use a reed switch or microswitch.
Likewise, a microswitch operated by a cam.
Look at domestic light switches though you might also need a relay if a heavy inductive load (large trafo).

Thank you, Russc
Now you give me ideas and I start to see why I couldn't find an end (in the supplier's jungles)
reed switch, woahaha! that's new to me!
The light switch is obviously good too! (kind a the brutalist's way to go, in a positive sense), and the relays-concept I was already aware of ( -> Mark Johnson's gizmo...) but wasn't yet ready to dive in. the beast (F4) is still a straight-forward power-amp after all...

A couple of projects which use aesthetically beautiful, but scrawny weakling switches (low voltage, low current) to turn on the deadly macho AC mains power
Project 166
PCB: low voltage On-Off switch drives AC mains relay \ includes soft start .. H9KPXG

An old USB/Phone charger makes a good (usually free) 5V standby supply.
Those black switches would look cool with matching facia. Solid black perspex comes to mind.

Which reminds me of the good ol‘ times—back then we had black glass (colored through) as tiles ... its as unobtanium as can be nowadays.Solid black perspex ...

I‘m already considering the use of this mysterious „H9KPXG“... 🙂 🙂 🙂
The real problem is that I a) already got toecutters softstart and b) that starting to look into the scrawny weakly switches would drown me in options and alternatives.
(That means: I probably will.)
Thanks already!

most probably, the front panel (some macho 10mm Aluminium) isn't suitable to incorporate a invisible capacitive switch (like, have a verrry thin marking around the capacitive area) because it's conductive, right?
I really like those designs
the Adorne Wave switch is nice, too. (If the "button" was a glowy red lens, we had a HAL9001 -> Nelsons Profile Picture 😎 -> then I had to incorporate a startup-/shutdown chime from the movie, haha)
After some more surfing on the switches, accompanied by thinking about, well, it’s function, I realized that it is better to keep it discreet, if not boring. Because if it was a nifty piezo/touchless/etc. thingy, somebody for sure would like it and play around-onoffonoffonoffonoff—which I guess is not recommended...
So, scale it back, dave

I recently returned to the classic - toggle switches (APEM is very high quality) or the large flat 19mm (easier to press inside with big fingers) push button switch. I have gradually given up the illuminated round led push button switches - I have probably used them too much.😀 and it's not good that the mains is close to the DC led power contacts on these switches - I better seperate indicator for safety reasons.
i like when the switch is on the front panel

Nice builds, oscar!
My chassis will be a black aluminium "cube", 4U x 300. (a almost standard Modushop-classic, that is, housing a F4(less) amp)
I'm still not sure. the rockers are so cool because it's really really classic design, but it doesn't fit into my idea—it's too classic 🙄 while the 19mm push-button is rather ... dominant? (It fit's your front panel very well though, chrome on wood is good...)
I have the impression that the switch should be "outstanding"—not only in terms of quality, but even more so physically. The, uhm, "tactile impression" should reflect what it triggers: a rather big amp. It should somewhat go "ka-chunk" rather than a barely audible "click", but it has to be nice to the touch.
I found a completely black version, but there's also the idea of a rotary switch (90° or 45°, or even better a switch where the rotation is non-directional, horizontal is off, vertical is on, CW/CCW doesn't matter..., you turn till it clicks to switch to "on" or "off", but I've only found big switches for wall-mounted home-appliances (washing machines etc.).
And, going even further, I'll probably must create a "handle" for it, following my own aesthetic guideline...
This switch: here
That switch: here
nice datasheets with good documentation: bulgin
(I also could imagine a nice amp—for freestanding use—with a BIG (D=20, H>=30 approx.) push-button on the top/cover of it, which would give the box a tad of irony...)

I somehow don't like the plastic switches in the aluminum panel ... these 19mm also have a matte surface version, but unfortunately I don't remember where I bought them. They are also available in black.They presses very very gently and without a loud "click"
Of course, fastening to a 10mm panel can be more difficult (thread short) - you have to drill a recess on the other side ...

Thanks, mark!
But—I beg your pardon—what makes you think I was after a rocket-launch device? [emoji16]
I am after a sort of equilibrium... i want it to be (kind of) noble, fancy, obvious...
Y‘know...
(Just like the monster-switch on the PA-7 but different)

Thanks again osscar!
Do you know What tool I could use to drill the recess into aluminium?
