If I use a DPDT relay (one suitable for switching mains), is it safe to have the relay switch 240V mains power via one contact ('Active' line), and 12V via the second contact? I am trying to avoid using 2 separate relays.
If you think it's quite safe, is it possible that the 240V could arc over to the other contact inside the relay? If so, is there something I can do to avoid this? For example, a capacitor in parallel perhaps?
Note: The relay is simply switching on/off a low-power battery charger (specs say 'Input=230-240V ~ 0.1A'), so we're not talking very high currents here.
I won't go into great detail here as to why I am switching 240V and 12V.
Thanks.
