Electronic Switching. There are many transistors that can be used to switch relays, but low power MOSFETs have several advantages. Chief among their benefits is the fact that the gates draw no current, so if you use electronic switching it becomes possible to maintain power using a 'super capacitor' - typically these are 1F at 5.5V maximum, and one can hold up CMOS logic circuits …
