How to wire a SPST Momentary yellow ring Illuminated switch

[Ripper]

I can't find a diagram. Is there one? I blow out every swith I get. I need help! I have a 220ohm resistor this time. lol

You will wire the LED just like any accent LED. So, based on your setup, you can wire it off of your battery pack or off of your board. If you look on the switch, you will see some markings on it that tell you where the "+" of the LED is. The pin directly across from that "+" pin (on the other side of the switch) will be your LED "-" Hopefully this helps some!

http://led.linear1.org/1led.wiz is your friend. What are you using for power? We can't figure out source voltage without that info.

Also, http://www.thecustomsabershop.com/As...ges/SMRNRc.jpg shows the contacts for the LED in this switch.

What is your power supply? 220ohm is good for 6v of input power. If you are using something different then that resistor is not correct.

According to the stats in the store the LED's forward Voltage is 2.1v and it operates at 20ma of current.

Using information in This Sticky From the General Hilt Building thread will give you the formula that you need to figure out what resistor you actually need.

And going to The Product Page in the store there is a drawing of where the posts are for wiring your switch.

I will be using 4 AAA batteries. Thanks guys! I love this place.

[Silver Serpent]

That'll be 6v if you're using regular alkalines. (1.5v x 4 batteries = 6v)

As Zzan said above, a 220 ohm 1/4 watt resistor is what you'll need for 6v.

Thanks. Tim was out of 220ohm 1/4 watt. So I checked out RS and found some 220ohm 1/2 watt resistors. It's a lil more but it should be OK, right?

[Silver Serpent]

Yes, those are fine. Wattage is a minimum. You never go smaller or you risk burning up the resistor, but you can always go larger. You could use a 10watt if you wanted, though it'd take up a ton of room

Silly question that's been bugging me: It says to use a resistor for the illuminated AV switches. The first thought I had was that this would lower the current from the battery pack to the switch. Is the LED inside the switch wired separately from the switch itself, or is this a one-piece wiring job?

[Silver Serpent]

Two separate circuits. The switch and internal LED are wired independantly.
