Hi!

I was looking for some small rotary switches, smaller than the typical Lorlin CK series. The Lorlin is rated at 1A/24v AC/DC. I found some china Aliexpress 9mm switches, but their voltage rating made me doubt. (16v dc 100ma). Is this enough for audio signals, given a dual supply of +/-12v or +/-16v.?? I Think it is, as i should think in terms of dbu levels. But I ask to be sure..

If you're not putting mains power through those, i wouldn't orry. I can't visualize how close two metallic parts would need to be, to manage to have 16-30V arc over the distance between them. And i'm assuming you won't need to be passing 100mA through them either?
 
Audio signal, even at line level are around <1mA and the rated voltage will be less than 10 volts.
Alli depress may be the way to go for you.
