Relay Spacing?

[MrSony]

Does it matter? Will voltage jump from one to another if they're too close?

Going to use this diagram UNGN posted a while ago that uses 4 relays for my 4th gen f body fans. Both low (half) speed then both high at say 200*f temp.

Going to mount them all together and wondered how much if any they need spaced apart. Any input appreciated.

I've never had a problem with them being right next to each other. Sometimes you can get a backfeed spike off the coils, though it rarely causes an issue.

I have 5 relays mounted side by side...low beams, high beams, one for each fan and another for the fuel pump. You don't need social distancing when it comes to relays

Go with the if any - even ready made boards put them together.

Not enough voltage or amperage to jump. Each wire is insulated, right?
