Not sure this is the best place to post this but… Here goes!
I’ve built a bunch of DIY preamp rackmount boxes over the years, and have generally always just plugged them into a Furman or power strip and used that for on/off power switching duties.
On my latest build, I can’t really do that as easily because of where in my rack it will be placed. I want to add a power switch to it. Unfortunately I don’t know how!
Specifically, this unit uses an external switching power supply with 5 pins. The pinout is pictured below, but it is:
Pin 1 Shell/Floating Ground
Pin 2 Common
Pin 3 +16V
Pin 4 -16V
Pin 5 +48V
The PSU feeds an internal filtering PCB which then distributes clean power to the rest of the unit.
So where, how, and what type of switch can I use to achieve this? Do I need a relay between the PSU and the switch or something? I literally have no idea how to do it.
The unit runs on 16V and the PSU will always stay plugged in. But I want to be able to turn the unit off and on from the front panel.
Would really appreciate some advice! I’ve read all sorts of confusing stuff about how to do this and whether or not it will cause audio problems.
For example, can I use something like this? Gebildet 0.87''/22mm Stainless Steel Latching Push Button Switch 12V-24V/5A Power Symbol LED 1NO1NC SPDT ON Off Waterproof Toggle Switch with Wire Socket Plug (Blue LED) https://a.co/d/0GEjZj8
Or does it need to be like this? Limited-time deal: Nilight 90012E Heavy Duty Rocker Toggle 15A 250V 20A 125V SPST 2Pin ON/Off Switch Metal Bat Waterproof Boot Cap Cover-5 Pack, 2 Years Warranty https://a.co/d/a8dRXLn
I’d really prefer something with a light on it, or the ability to add an LED to it somehow. I can only drill round holes, no squares. No tools for that.
Attached below is a picture of what I’m building, although that is not my unit, it is the same thing I’m making. I’m almost done so figuring out the final details now.
Thanks!
