Light switch system

There is provided a light switch system having a housing and a controller secured to the housing. The controller is to control a light source to generate a light output based on a demanded output. The light source is to illuminate at least a portion of an operational volume. The light switch system also has an occupancy sensor communicatively coupled to the controller. The occupancy sensor is to generate an occupancy indicator to indicate whether the operational volume is occupied. Moreover, the light switch system has a functional module communicatively coupled to the controller. In addition, the controller is to divert power from the light source to the functional module by controlling the light source to a the light output to produce an altered light output based on the occupancy indicator.
