Hello,
I'm pretty new here so please be kind.
I have a quick question.
So I was dissembling this type of flashlight.
And got this KAN-17 Button
What I'm curious about is that the rating voltage & current are 50V & 0.5A. From what I understand, please correct me if I'm wrong, is that if a device says it needs a particular voltage, then I have to assume it needs that voltage. Both lower and higher could be bad.
For current of a power supply; it must be at least what the device wants.
The flashlight is powered by 3 triple A batteries and if I'm not wrong 3 batteries won't produce more than 10V let alone 50V.
So why does it work? Or how does it work?
And this all comes down to the fact that I want use this button for my little LED project with the Arduino Uno. If you can please help me understand or link me to website you believe would help me understand these basic concepts.
Thank you!
