20140420 P-channel Power Switch

This switch features pushbutton on and off action, as well as ability to actuate on and off through the 100-mil header. Power handling up to 20A, depending on specific P-channel MOSFET used and tolerance for board heat.

I have ordered, built, and tested this design, and it works well. Leakage current when off is below what I can measure – approximately equal to zero.
