Hello
New to the forum. New to the world of electronics. I'm trying get the electronics set up correctly for my fist project, a small fan to keep the solder fumes out of my face. I finally figured out how to wire up the LED switch so when pressed, the fan (also with LEDS) comes on with the LED switch also lighting up. However, I've blown the LEDs in two switches already once I adjust my power source past 3V/.5A to get the 12V fan working at a reasonable speed. I have a 1000 Kohm resister in the circuit but I don't think I have the circuit set up correctly.
Can anyone help? Is there anything else I should be adding in the circuit other than the single resister?
Specs:
– 9VDC 650mA wall power source that will plug into the back of the fan box.
– 12v DC panel mount 2.1mm power jack
– 4-pin 16mm 12v DC pushbutton switch with LED (not the Adadafruit 5-pin metal ones - these are the plastic ones)
– 12V 120mm computer fan with 4 LEDS in each corner
