[QUOTE="pootler, post: 8736326, member: 682303"] O.K, Had a look at these things - and played with a few. I don't think the off the shelf version suggested is compatible with my requirements, as the timer starts when the coil is energised. I think it is meant for something like delaying powerful headlights ( or other current hungry devices )from coming on immediately, during engine cranking. I need a relay that will be permanently energised, and then changes contacts ( for a set time ) when de-energised ( that is , when the 12V acc feed loses voltage.) It then switches to a constant 12V , eventually returning to the original contact state after the timer runs down. I believe it is a NCTO or NCTC relay. I am trying to see if there is a module available. Will post any news. Cheers pootler [/QUOTE]
