I am trying to wire up LEDs for a double-slip on a friends layout.

Going straight through the slips from any direction the LEDs are ok.

When you set the motors to go through a curve on the slip, the opposite side bend lights up.:bang:  

After sleepless nights and mental brain drain I am at a loss. :doh:  

There must be a solution, so does anyone here know what it is?  :sad: :shocked:


My next thoughts are heading down the track of using relays and or diodes,

but I hope someone has a better solution and save me a lot of time.

Could you post the circuit you are now using?

Try this.

When tracks are set to go through a curve the opposite curve LEDs light up.

When going straight through the slip all is ok.

And what now is the problem?

Doesn't this circuit work for you?

Ah, so you need to combine the information of 2 switches to get one LED lighted up.

I would say that calls for a logic element, and in your case I think an AND gate will do the work. 

I suppose the switches work with the support voltage of the switch motor?
So may be easiest way is to built such a gate with from transistors by yourself, so you are not limited to 5V.

Here is an example

Thanks for your reply Juergen,

I had thought of some gates.


As my friend has wired the track and points,

I think it's time to rewire them so I know it's correct and take it from there.


If that doesn't work, gates will be the answer.

PROBLEM SOLVED


Using a Peco double-slip with Peco point motors and switches (as before),

I redesigned the circuit so one switch has power fed to the switch common and LEDs to make them operate,

On the other switch the power feed was reversed so I could use the polarities to operate an extra LED when the appropriate LEDs lit up.


Thanks everyone for your input. :2t:
