DCC/DC Change over switch

[RonnieS]

I am doing a bit on a club project and looking forward to early next year we could do with something similar to this

 http://www.rpc-electronics.com/dcdccswitch.php

I can not find anything UK similar so HELP please

I must be missing something here. If the entire layout is to be either DC or DCC then a very simple and cheap switch is all that is wanted. A 2-pole, double throw latching, with centre off, will do what you need. Switching from one to the other goes via 'off', so no risk of the two systems clashing, which can be expensive. The output to the layout is from the centre contacts, the inputs are on either side.

Yes of course. No need for bells, whistles and flashing lights!

If you want that same switch then see RS 134-1144.

 

However, as Oldddudders says, all you need is a DPDT switch. The 9v supply to the switch is only to illuminate the LEDs.

 

If you want LEDs attach to the track output.

Thanks guys. DCC is not my scene but on a club layout it has to be catered for, And in a fool proof way.

If I may come in here, can I ask please is the layout 2 or 4 tracks.

 

Thd reason I ask is that it would easily accommodate dc & dcc locomotives better if the layour is built with 4 tracks, 2 would be for dc only and the other 2 for dcc only.

But that introduces a new risk. Any connection, due to derailment or simply a metal tool left across the tracks, could cause electrical connection between the DC and the DCC. This can instantly zap some of the electronics in the DCC system and cost real money. 

 

Not recommended.

AC doesn't do DC motors any good either.
