fun stuff... use cases?

here is a couple...

1. profile location switching. pin 1 on/off = work/away - switch system configs appropriately. 2. desktop workspaces, flipping pin 2 on enables workspace switching. pin 3 and 4 control workspace number.

What else?

With this sort of switch you have to worry about the lifecycle of the switch. They aren't meant to be toggled routinely. For the mentioned DIP switch (https://www.farnell.com/datasheets/5461.pdf) it's basically assured it'll be fine through 1000 cycles, and likely dead at 10,000.

1000 cycles is only ~3x/day for a year.

addblock on/off, javascript on/off, vpn on/off, qwerty/dvorak, default editor is vim/emacs, indentation is tabs/spaces, the dress is blue and black / white and gold, fund police/defund police, those are/aren't the droids we're looking for

A form of two-factor authentication? (Something you have + something you know.)

Simply set the value to match a rotating 8-bit token and plug-in to login :)

Integrate with Linux bootloader / boot process.

pin 0 on = normal boot, pin 0 off = single user mode.

pin 1 on = GRUB interactive screen enabled, pin 1 off = GRUB interactive screen disabled.

Same idea but a switch: https://hackaday.io/project/179539-hardware-boot-selection-s...

I had something like that hanging off a parallel port in a PC in 1990; it read the status bits of a printer port and booted accordingly. Could still do it today, via a $1 USB serial port's status bits.

This could be useful for conferencing on the go. Toggle switches for webcam, mic, mute, uhh...different channels?

Could be useful with home assistant in a lot of ways, though your use cases kind of cover them.
