I'm trying to select switches for a Teensy 3.0 powered soley by the USB (no battery or external). If I look at a site like Mouser, they have several ratings that I would like to know the meaning of:
The switches will primarily be pushbuttons used as input to digital pins. I just want to ensure that I get switches that can handle what I suspect is not much "power" from the Teensy.
Google is not my friend in this case, Mouser doesn't have a glossary, and I couldn't find anything in this forum.
I'd appreciate "keep it under/over xyz" or links to further reading. I just can't seem to get any info on this.
- Current Rating - Ranging from 0.1 mA to 20A
- Voltage Rating AC - Ranging from 4.5V to 600V
- Voltage Rating DC - 0.5V to 600V
- Power Rating - 0.1VA to 50VA
