Abstract
An apparatus and method for controlling a motion sensor switch which is adapted to control a lighting circuit in an area monitored by the motion sensor switch. The apparatus and method employs a setting adjustment device, such as a potentiometer, having a setting range which sets the duration of a delay period during which the motion sensor switch delays deactivating the lighting circuit after sensing that the monitored area has become vacant. The setting adjustment device further includes a first setting position, a second setting position, or both. The apparatus and method further employs a bypass controller, such as a comparator circuit or software-implemented comparator, which, when the setting adjustment device is set to the first or second bypass setting position, controls the motion sensor switch to maintain the lighting circuit activated or deactivated, regardless of whether the motion sensor senses motion in the monitored area.
