Quick relays question

[dirty1_1garry]

Hello!
During creating relay bypass for one of the my project, I've ask a question to myself regards better electromagnetic relay performance (For example Omron G5V-2). As I have no an answers, I want to ask  all smart guys here about that.

My relay performance understanding :
When relay is out of power control pins switch to first contact group.
When relay is on power electromagnet pull control pins to second contact group.
Does it mean that quality of contacts is qual in both positions?

What is better:
bypass (device omit) > relay on, active > relay off
or
bypass > relay off, active > relay on

Cheers,
Igor

Ask the relay factory.

(They probably do not know about audio.)

"Most" relays use all the same buttons for all the contacts.

However I just looked at a "specific function" relay rated 10A NO and 1A NC, so it probably uses smaller buttons on the NC path.

In broadcast the ONLY way was "off" = "bypass", so if the power to that box failed, signal would get through. (No-dead-air is more important than fine signal.)

Don't use power relays to switch small-signal audio.
Use a small signal relay, intended for audio signals (such as PBX relays from NEC).
Google 'wetting current' to understand why.

I use signal relays of course as Omron G5V2, that's just my bad explanation))

No, he's yelling at me for mentioning 10A contacts in a thread about signal relays.
