    Can you get dual input relays?

    As above really, can you get dual input relays 12v automotive relays?

    I'm looking at some projects and thinking of OR and AND dual input relays....

    Thanks in advance.

    Just connect both of your triggers onto one relay, and use diode's so the don't back feed

    I was hoping the would be relays with the terminals already there and the diodes inside, for neatness as much as anything. I'm thinking that what you said is going to be the best way though...........

    If it's on show, put some heat shrink over the diode and solder in into the end of the wire

    Yep, not as neat but just as functional.

    sorry to hijack youur thread but im looking at advise on diodes aswell looking to put undercar neons on my car i want them to be fed from a switch for show use but would also like them to come on for say 5 seconds when i unlock the door think a diode is the correct peice of equipment to put in from a feed from the contral locking unlock wire but i dont really know what kind of diode i need does anyone have any ideas.

    also any advise on a time delay style relay that could keep them on for 5 secs or so

    sorry for going on a bit many thanks

    That would draw a high current though, probably a timer relay is your answer

    You could consider a 12v fused supply to a changeover relay that get switched in by a timer delay circuit, triggered by the central locking. BTW I believe Maplin do a low-power timer delay circuit (if its only being used for control of the relay you won't need high power rating, however the relay would need to be higher power rating).

    You could even put two in a row and have the second relay triggered by a switch ofr show use .

    I need to give it some more thought but happy to develop this further........

    why do you want dual inputs?
    if your worried about space get circuit board relays fabricate it on a custom made circuit board and it can be as little and compact as you want.

    The initial plan is to have a 'flash and fogs' setup to bring the fogs on with the full beam. However, I wanted to extend this to only happen if the side (or dipped - not decided yet) lights are on. If this could be done in one insulated automotive relay (15amp/20amp) that would have been ideal ...................
