Somehow i cannot get this setup to detect "ap" pressed.. Any hints ? i just used your scripts, except that in /etc/config/system , i just log the actions , i will define other handlers as needed . Like so :

config button
option button '3g'
option action 'pressed'
option handler 'logger 3g selected'

config button
option button 'wisp'
option action 'pressed'
option handler 'logger Wisp selected'

config button
option button 'ap'
option action 'pressed'
option handler 'logger AP selected'

Thanks !!

Not sure if folks are still using these scripts, but I wrote a package that makes detecting slide switch changes easier: slide-switch
