12mm Ring style illuminated momentary buttons. Includes nut to internally secure button. No internal resistor so be sure to get the correct resistor! Blue/Green/White: 3v, 20ma Red/Yellow: 2v, 20ma Resistance calculators are available online, such as this one: . Type in your supply voltage, probably 3.7v if you're using a 18650 battery, forward voltage is above, forward current 20ma. You'll generally get 35ohms for 3v leds, 85ohms for 2v leds. For illuminated buttons, you may go with a bit more resistance if you want, as high brightness isn't typically a huge factor. Of course, that is personal preference! * Please allow 24-48 hour order processing time before shipping *
