I would like to connect two sets of speakers up to my hi-fi system, however only have one set running at any one time, which is selected using a DPDT switch. I have included a picture to indicate what I mean, so hopefully it'll tell a thousand words so everyone understands what I'm trying to do.
Specs
Switch: ON-ON || 3A 250VAC || 6A 120VAC
Speaker Set 1: Impedance 8-Ohms
Speaker Set 2: Impedance 6-Ohms
Hi-Fi Amp: Power Output 95W + 95W (at 6 Ohms, 1kHz, 1% THD) [values pulled straight from it's book]
If you need any more clarification then please do ask .
If this is a higher power audio system it may not be too good of an idea to hard switch the speakers under power. The amplifier itself isn't going to like to go from a loaded to unloaded condition instantly, and the unload speakers are not going to like being switched if there's a peak on the line. Aside from some nasty ticks and pops when you switch the speakers there's a chance for speaker damage.
