As with lamps, graphics which change in accordance with the status of a set bit
are set for touch switches, and, besides, an area where the touching of the touch
switch can be detected (the touch switch area) is also set for them.
Touch switches are arranged and set on screens when creating screen data with
the Support Tool.
When a touch switch is pressed, the function set for it in advance is executed.
