Of most models I don't know what is here to prefer and to avoid.

Thank you very much for your comments.

The decisive factor here will be the quality of contact material that need to process the voltage flash of inrush currents - especially by large main transformers - so I think.

really no experiences with various main switches for audio components?

A plain 10A relay works better than any switch I know of, so why use a switch?

Have a look at Honeywell AML34/36 Series Power-duty Rocker Switches.
Specified to 15A at 125VAC and 250VAC, and have silver contacts.
They are very expensive though.. I use them in my power amp.

For new projects the royal way. But to replace cheap and worse versions in existing audio components against that one of higher quality usually associated with too much trouble causes through various modifying.
Therefore I prefer there the kind of switches mentioned at post #1, but in "long life" and high quality versions.

Dagen: Honeywell AML34/36 is a good advice - thank you

Push-button switches of excellent quality are manufactured by EAO in switzerland. Their series 04 offers even aluminium front rings and buttons. Hard silver contacts for high reliability and high current rating. Nice parts that make the use of auxiliary power supplies to power relays completely unnecessary.

Contact EAO and ask for their nearest dealer as EAO is not available at the common distributors.

Have fun, Hannes

This is the brand, inside by old Naim Audio power amps like NAP160 and NAP250 (formerly LUMITAS as I know). Expensive, but I must never replace this switches by service - therefore one can assume very high reliability and life time.
Pushbuttons, push buttons, 8mm 16mm 22mm Push button switches, illuminated switches, LED pushbuttons
Thank you for this advice.

I have had very good luck using these.

Carling Tech: C100B Series

There are also push button types that fit in round holes.
