+Throughout this chapter we will be using the _light switch_ state machine as an example. It models a lamp which can be turned on and off and also supports various brightness values.
 
 If you press the _pressLightOn_ button, the lamp turns on at its lowest brightness value. If you operate _pressLightOn_ repeatedly, each time the lamp becomes brighter until it reaches its maximum brightness. Pressing the _pressLightOff_ button, immediately turns off the light completely. The brightness can only be raised as long as it hasn't yet reached its maximum value of five. After that, the guard condition disallows to raise it any further.
