 From documentation [1]:

"The default state of a switch is LIBINPUT_SWITCH_STATE_OFF and no event 
is sent to confirm a switch in the off position. If a switch is 
logically on during initialization, libinput sends an event of type 
LIBINPUT_EVENT_SWITCH_TOGGLE with a state LIBINPUT_SWITCH_STATE_ON."

Cheers
