Relays to use in speaker selector

smithy666 · 24th May 2008, 03:17 AM

I'm looking to build an A/B speaker selector and want to use latching relays rather than a switch. Can anyone recommend good quality latching relays that will handle 150W+ without degrading the signal?

When choosing speaker relays, the Current (A) is also an important parameter......
Is the 150W+ into 8, 4 or 2 Ohms ?

Minimum load of 4R

If so there are many types to choose from, e.g. Finder 40xx series, Finder series 65 or Amplimo LRZ and more.....

Edit: Sorry I did miss the latching part.....
To early in the morning here

I'm using Schrack RT314/315 relays(1 pole, 16A with NiAg or NiAgAu contacts). Very good toys
