Replace the lightbulb inside with LED and use it with 3V circuits!
There is also a plenty of benefits of using LED in the switch.
Go and check first step!
Step 1: Parts you'll need to convert your switch and why do you want to do it.
- LED doesn't get hot when in use - lightbulb does.
- LED uses 3V instead of 12V that bulb uses and the switch can be used in low-voltage projects.
- LED is much brighter! (you can even use switch as a flashlight when you fit inside the hi-power LED)
Idea to replace the bulb in the switch came today, when I was going back home from the electronics store, because I bought a switch for my USB charger and I realized that the bulb inside uses 12V and the maximum voltage in my USB charger is only about 8V...
And there was another problem- even If I would use the lightbulb it will discharge my battery much faster than LED.
So, if you know what we'll going to do, let's see what you'll need for this project:
-Switch (of course)
-LED (in this case- SMT LED)
-Any thin wire you find (I use some silver plated wire)
-Solder and soldering iron
And optionally- some grease.
