Silly power question

I am using this method of a capacitor and 2 resistors per switch.

Hi
Then no, I would look for a dc PSU 18 to 24 volts Something like an ex laptop PSU would be ok.
You MUST use a dc power supply not ac for this circuit.
Something like this one on ebay (one of many available) ... ebay PSU link

Will this one be ok?

Hi
Yes that would be fine.

I am using this method of a capacitor and 2 resistors per switch.

The 2 devices are diodes, NOT resistors...!

Sorry Steviesparx was very tired when I wrote that message.

Thank you for your help Flashbang. I have now ordered that adapter

Hi all,

Sorry for resurrecting my old post.

I'm a slow person when doing my model trains and starting to get to the time for wiring up the points.

Quick question...

Would the above work?

The idea is to throw 2 points at the same time. I don't know the technical term but the idea is to switch both points so that when moving to another "loop" they throw at the same time to lower amount of switching needed.

Anyone?

it might work, but a better solution would be to use a DPDT instead of a SPDT
That way, both points would through at the same time, but the electricals would be separate
BTW, a DPDT is like to of the switches you have there, but they only have 1 lever between them so they both throw at exactly the same time

Hope this Helps
