Hi.
I recently began using a design that feeds 3V into a Pololu Pushbutton Power Switch LV. The documentation says that “at low voltages, the switch is difficult to turn on”, and indeed I have a couple of instances where it is “difficult” to turn my projects on. (One won’t turn on at all anymore, and the other requires shorting the board with a screwdriver.)
I’m wondering whether I am encountering the documented problem. Is 3V “low”? The part is rated to 2.5V, so I assumed, possibly incorrectly, that 3V would be “normal” and not “low”.
I’m using the switch so that my Arduino-based project can turn itself completely off. Is this a good application for this switch, or should I seek another solution?
Thanks,
Mikal Hart
