Activate Switch with a button

[DerVVulfman]

You need to first check if the button is pressed (regardless of the switch).
THEN... you toggle based on the current switch condition:

Code:

if Input.trigger?(Input::L)
  if $game_switches[2] = false
    p "on"
    $game_switches[2] = true
  else
    p "off"
    $game_switches[2] = false
  end
end

And as MechanicalPen stated, remove the 'p'/print statement lines when you're satified.
