I'm in the process of repairing a lamp that I found with a broken switch. I know the lamp mechanism is functioning because I've bypassed the switch and plugged it in and it works fine. I needed to buy a new switch and they all have a current rating. I'm using 1 60 W bulb with a standard North American 125 V outlet. I thought P = IV --> I ≈ .5 A. Using this info I purchased a toggle switch rated at 5 A for 125 VAC (so at least 5 amps of current can flow through it right??) and tried adding it to the lamp. Didn't work! Does anyone know what I might be doing wrong or how to determine the current rating for the switch I'm attempting to add? Any help is appreciated. I bought the switch at RadioShack if anyone is interested. Thanks!
