Hi Again, I tried to send out a question about a project and messed up. Sorry. Here is my second attempt:
I have been told that I can use a SCR to replace DPDT "latched" relays in the following project: From a transformer, I have both AC and DC power. The AC goes to a "momentary" on-off-on slider switch. Slide to left, push it in and release, hense the momentary. This engages my track turn out in that direction. Slide the button to the other side, push and release and it switches the turnout to the other direction. The momentary switch has three wires connecting it to the turnout motor, one for one direction, one for common and one for the other direction. The switch motor is an engerized coil that mechanically moves the switch.
Here is where I need your assistance: From the same outputs on the momentary slider switch, I connect wires to a DPDT latching relay. This latching relay has an input for DC + power and two DC + outputs. Engage the the switch in one position, the DC power goes out one output, for example a Red LED. Engage the switch in the other direction and the DC power goes out the other output terminal to my Green LED. I have been told that I can use a SCR to replace this latching relay. I can't figure it out.
I am a novice at this electrial stuff and can't read electrial diagrams worth a beans. I don't know that I want to quit using the latching relays, but the one provided by the "hobby" and Atlas #200 Snap Relay takes up allot of space and are expensive if you need allot of them, which I do. I am looking for a space and money saving method of replacing the the snap relay (DPDT Latching relay). I will attempt to attach a diagram that I created using "Paint" (bitmap drawing) illustrating what I am currently doing. Maybe some out there can help me save money and space. Because I had to shrink it in size in order to post it, you may need to open it, save it and enlarge it in order to view the diagram. Thanks.
