Hi there, and welcome to the forum.Hi guys,
I am looking to use a switch with an LED and a resistor. Is my wiring and placement of the resistor correct?
I doubt they are designed for continuous operation. They are probably only designed to work for long enough for you to find your keys.Hi Sceadwian,
My son gave me a keychain light with a white LED, three 1.5V alkaline button cells and no current-limiting resistor. It burned out after lighting for no more than 1 hour.
