All this must sound a little odd for someone who is lighting his kits but...

I want to put a switch onto the dispaly base for my refit build rather than just using a socket and plug from the battery (my plug n play method). I am pretty sure I will just run it off a 9v battery cause that is what i have set it all up as. I would like to use a plug pack but I'm a tad confused (not difficult really) about the milliamp side and power regulation issues.

I know I can mount a mono plug n socket inside the kits display base for connecting the said battery or thru the outside for a plug pack. However its the switch side of things that got me stuffed. Just a simple toggle switch would do the job for me but there are things I'm a little unsure on such as... Wireing it up correctly, or... If running off a battery is it so important to watch the voltage for the switch and do the number of leds matter as well..??

Cheers,

One confused Aussie. :wave:

I'm not an Electrical Ennineer, but I've found that most all of the switches I use from Radio Shack are the 120V type. I don't think you have to worry too much about the mA or power regulation issues.

As to wiring the switch, it all depends on where you want the switch in the circuit. Without knowing what type of switch you have in mind makes it little difficult to give advise.

Good point Dan...

I'm thinking to keep it as easy as possible I was planning to have the switch between the battery and the connecting wires into the model. As for the switch I was thinking a slider or toggle type.

Hello Alek,

I hope this helps, call me if you need any help with the switching.

Good luck!

DOH!! How simple is that... :o I thouhgt it would relativly straight forward but damn. Once again I just over think and complicate things :p

Thanks Randy :thumbsup:

All you need to do is get a 9-volt power supply sized to your current load. Cound the number of LEDs, multiply by the current draw by LED (add in any other components) and get a power supply a bit larger than that.

You can get plugs to connect the power supply from any electronics store.

Thanks bigjimslade.:)

So if I understand this correctly :confused:

I need a 9v power adapter that outputs a minimum of 720ma because I will be running about 36 leds with an average of 3v and at 20ma each with its own resistor.

Do something like 1.5 amp power supply to be certain.

Sooo much to learn..... :freak: Randy @ VooDoofFX also suggested a 1500ma as I am running his nava board as well. I know that Dick Smiths over here has a regulated multi-volt plug pack that is 1500ma so it looks like that is what I am getting. :)

Many sincere thanks to every one for their tips and help.:thumbsup:
