Resistor Colour Charts

Here are some resistor colour charts for those who need it as well as the ohm's law circle. Pick whichever works for you as they are all the same :)

As a follow up

Wiring for switches is a very good site for figuring out your wiring if the switch comes with no instructions. Like mine.

Soon I will be posting a list of the paraphernalia I have bought thus far for this kit. Going to take it slow.. I have bought maybe a couple switches, a couple computer fans and thats about it. No going nuts on this one as LLL would say :)

Two options of wiring that switch!

The two diagrams below (courtesy : http://www.bcae1.com/switches.htm ) are the two methods of wiring this switch. Thanks Neil (VE3SST)


Option 1

Option 2

Going with option 1!

Wiring? - Double Pole ON-OFF

Double Pole ON-OFF, Illuminated Rocker Switch


Please have a look at the two picture above (click to enlarge). The following is with respect to the items labeled 1,2 and 3 of the switch in the diagram above.

- When I connect my multimeter to prongs 1 and 2 of the switch when it is in the OFF position, I get no continuity. Good
- When I connect my multimeter to prongs 1 and 2 of the switch when it is in the ON position, I get full continuity on my multimeter. Good
- Prong 3 of the switch has NO effect on continuity in any combination (Prongs 1-3, or 2-3 etc) whether the switch is ON or OFF
- This is an illuminated switch and Prong 3 has a symbol of a lamp etched on it...

I am using this switch to control power to the LOAD (which could be a fan as an example). The normal connections I would use are:

A1 to 1
2 to L1
A2 to L2
A3 to L3

What I DON'T know is how to connect prong 3 of the switch to make it light up... Any suggestions would be helpful

Here is a closeup of the switch:

Thanks and Regards

My Carry and GO

Following some posts made in the YRARC yahoo board, I decided to build a communications GO Kit. Don't know what I am going to call mine yet. So far I have decided on the case I am using. A pelican 1550 in ORANGE. Here is the case. Of course, the one I am using is without foam. Will be posting progress as I go along :)
