I have a situation where i'm supposed to turn of one line and turn on another line at the same time. Actually, it would be great if there is slight delay between those switching to let the device be protective and to do it bit more safe. (Avoid sparks etc)
If i use two relays, i would not have that problem, i would simply make 0.5s delay between on/off of the relays and everything ok. But for the sake of using only one two pole DPDT relay, i need this.
The power lines that are used for switching could be 12VAC or 12VDC, max 1A current.
Any idea? Any suggestion? How to protect the circuit? Etc?
