This is what I see on my HP Envy TouchSmart:

$ sudo ./libinput-debug-events --device /dev/input/event18 --verbose
event18 - HP WMI hotkeys: is tagged by udev as: Keyboard Switch
event18 - HP WMI hotkeys: device is a keyboard
event18 - HP WMI hotkeys: device is a switch device
-event18  DEVICE_ADDED     HP WMI hotkeys                    seat0 default
group1  cap:kS
 event18  SWITCH_TOGGLE     +0.00s      switch tablet-mode state 1
^Cevent18 - HP WMI hotkeys: device removed
