As with lamps, graphics that 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.
The way a touch switch is displayed and the processing when it is pressed can
each be set independently.

Note Do not press touch switches with a force of greater than 30 N.
Applying higher force may cause the glass to break, cause injuries, and prevent
operation.
Do not press touch switches carelessly while the backlight is off or while nothing
is displayed on the screen. Otherwise the system may operate unpredictably.
Only press touch switches after confirming system safety.
Note If touch switches are pressed in rapid succession, their inputs may not be suc-
cessfully received.
Confirm that the input of a touch switch has been successfully received before
moving on to the next operation.
