PROBLEM TO BE SOLVED: To enable a plurality of devices to be driven to change from an optional ON pattern to an optional different ON pattern with a simple operation.SOLUTION: First to (N+2)-th main switches turn on/off first to N-th (N is an integer of two or more) devices to be driven. When the first to N-th devices to be driven are made to correspond to first to N-th intersection points, respectively, and the first to (N+2)-th main switches are made to correspond to first to (N+2)-th areas, respectively, an i-th main switch can turn on/off one or more devices to be driven respectively corresponding to all intersection points brought into contact with an i-th area about each i being an integer from one to (N+2)-th. The intersection points of the first to N-th intersection point are intersection points of one line closed on a plane represented by a one-stroke sketch in which three or more line segments do not cross at one point, the first to (N+1)-th areas are surrounded with the line, and the (N+2)-th area surrounds the line. |
