Confusion on illuminated switch
So I picked up the blue ring illuminated AV switch for my newest saber - http://www.thecustomsabershop.com/DP...itch-P433.aspx
I was getting ready to start wiring work, when I noticed none of the pins were labeled. Trial and error would be good enough to figure out the switching portion, but I didn't want to hook up the LED backwards. I pull out my trusty multimeter to check the resistance and polarity of the LED, and I get really confused.
The LED illuminates in both directions.
I'm not really an electronics guru, but I'm pretty sure that LEDs are supposed to only work in one direction. I got no change in resistance in either direction on the LED, no matter which lead I used as negative or positive. So, what is going on?
/me scratches head
Edit: I've got the "negative" marked according to the diagram shown in the store, assuming it's the closest to the 2 commons. Still don't know why it lights up backwards.

I have gotten 2 of these type of switches, if you look REALLY close under the glue there is a raised positive and negative symbol.

Is it possible that your multimeter has reverse polarity protection?
