You all know by now my dumbness in electrical bits.

Here is another one.

Set up as below:



On the left Peco SL10WE points; In the middle a DPT switch center off with 6 legs; on the right, turnout control panel in its simplest form with green & red LEDs and the black being the DPT switch.

Now, scenario is to be able to see on the control panel which way the turnout is thrown by means of LEDs.

All power will be analog i.e AC controled by transformer nothing to do with DCC.

How on earth do I wire up this combination?

Thanks

This page may help: http://www.newrailwaymodellers.co.uk/electrics-switches.htm

If you took "Mr Bulmer's" option (toggle switch PLUS push button to fire) then it will work. However, if trying to "keep it simple", I would do it with push buttons or centre-biased switches.

Ideally the indicators should be switched via contacts attached to the turnout motor, otherwise you can have the indicator showing one route, but the turnout actually failed to operate.

**Hi Baykal

I'm out of the office until Wednesday but I have lots of diagrammes there - PMing and diagrammes don't mix well so if you'd like to send me an email off list so I can send you some options plus some diagrammes directly addressing your need then please do so....

send it to sales<AT>DCCconcepts.com
regards

Richard

Already did, thanks Richard.

I don't think that you should use a DPDT switch with peco point moters. This is because the point motors require only a brief bit of current and will burn out if left on permanently (by which I mean more than a second or two). The DPDT switch will leave the current flowing one way or the other permanently. They must have passing contact switches which only give a brief flash of electricity each way.

Robert Hi,

I must have used the wrong abbrev. of the switch.

It works like this: You push it forwards and it automatically comes back to the center.

Thats me when it comes to electrical bits

Ah that's O.K. It's obviously a special type of momentary DPDT. Even so I think that a SPDT switch of the same kind would suffice and possibly be cheaper to buy unless you already have it. The central contact will bring current in and the outer two will take it to each side of the point motor.

I don't see how you can use this switch to work the LED as well, because that does need continuous current. However, somebody with more than my basic knowledge of electrical items may show you how it can be done.

Cheers, Robert.

A momentary switch (SPDT) of the ordinary push button type will operate the point as the solenoid only needs a momentary curent to get it to move. When switched again it should return to the original. This uses the 16 v ac of the transformer to operate. This The led will only light when there is momentary current through it. To stay lit it needs a constant current (but be careful most led's are only +/- 5v)

The led (if rated for 12 v dc) can be lit to show which track is live and therefore two leds are needed to show which track is live (the one lit up) and which is not (the one not lit up). It can all operate from a control panel much like in

http://www.modelrailforum.com/forums/index...?showtopic=5449

where expat has made a very nice looking control panel.

I have been asked to set up a circuit diagram. I will try to do so on the topic on the control panel.

essentially the led is wired so it pick up from eack 'leg of the track'

worked for me when I had my layout in the attic.

If you are talking with Richard ask him about his MasterSwitch product which includes the LEDs, the DPDT switch as you have drawn it and makes wiring up the points easy as and I am from the same lack of knowledge back ground and I got something working first try by following Richards instructions.

Hi baykal
I found a site for you with a points/turnout controller
I have seen this in operation
It works with 8 points per unit and remembers the position of you switches ,powers your direction indicator LEDs
Sidetracked Electronics

The system uses single pole double throw switches

Hope you find this interesting
Regards Zmil

***Ah yes, but very exxy, limited to 8 and not nearly as clever as DCCconcepts MASTERswitch :)....
