Switch wiring question

[DangerAardvark]

I have a bunch of LED rocker switches that say 110vac on them. Anyone know what exactly that means because I can't get the LED to work and those are the only relevant numbers I can find on the switch.

i'm guessing it means that those switches are meant for 110 volts...you'd need that much to get the leds to light up

canadageek got it in one. If a switch lists xxxVAC or xxxVDC on it, that means that's the voltage amount, and type it's designed to work with (AC and DC). Computer power supplies take in either 110 or 220 VAC and push out differnt levels of VDC to the parts inside the case.

Where did you get all these rocker switches, and why did you buy 'a bunch' without knowing exactly what they could be used for??

I bought 10 on Ebay for like 7$. Used them to construct a switch bay for the lights on my computer. So, you're saying that there's no way I can power the LED with the 12v line from the PSU?

I actually took one of the switches apart and replaced the LED inside with a 2.5v LED with an appropriate resistor. So, the switch has three prongs. The top one seems to enjoy power for the LED while attaching a ground to any of the other two will light the LED and will light the cathode VERY little. Attaching the cathode power and ground will to prong 2 and 3 will light the cathode just like any other switch. It's just getting the LED and the cathode to light at the same time that befuddles me. Hope that description wasn't too hard to follow.
