    Help with a simple relay switch oo gauge train modelling connecting two circuits together

    also just found that maplin doesn't have this one in stock or any that meets my requirements, did some searches and i have found this relay online and it seems to be the right one i think...

    Help with a simple relay switch oo gauge train modelling connecting two circuits together

    Also I just looked under the comments section on the map line website and discovered this about the relay It took me an awfully long time (and burnt fingers due to overheating components) to work out that these relays have an integral back-emf protection diode built in. It would have been nice...

    Help with a simple relay switch oo gauge train modelling connecting two circuits together

    So which wire should I connect to which pins ? And I don't understand where I am supposed to connect the diode ? Do I connect it across the two wires on the decoder ? Or do i connect it Across the two wires on the higher amp circuit? Thanks again you rock for helping me with this

    Help with a simple relay switch oo gauge train modelling connecting two circuits together

    Thanks for the help duke but I really would prefer to use a relay in this circuit, so will the one at maplins work which I have suggested? Also the positive and ground of the switching circuit and the positive and ground of the high amp circuit have to remain separate from one another, ie they...

    Help with a simple relay switch oo gauge train modelling connecting two circuits together

    The first one sounds good and the second not so sure about thanks for the info just quickly do u think that this relay will do the job it's available at maplins the reason I ask is because I live close to one http://www.maplin.co.uk/p/12v-dc-2a-dpdt-bt-type-47-equivalent-relay-n17aw

    Help with a simple relay switch oo gauge train modelling connecting two circuits together

    Ok essentially I do a bit of electronic work in my spare time, currently I operate a dcc oo gauge train layout at home which I run my electric dc steam engines on. Okay so put simply I want to use what's called a seuthe smoke unit or even build my own from scratch. The problem is that the smoke...
