Touch panel switches should NOT be used to make
a switch that could result in human injury or equipment damage.
Trouble with the display unit, units, and cables which keep the
output ON or OFF could result in a serious accident. An output
signal that could result in a serious accident must be equipped
with a monitoring circuit such as a limiter. Please design the
system so that important operation switches are handled by
equipment other than the display unit. This will prevent potential
accidents as a result of incorrect output or malfunctions.

Touch panel switches should NOT be used for a
device's Emergency Stop Switch. The Ministry of Health, Labor and
Welfare requires all industrial machinery/systems must be equipped
with a mechanical, manually operate emergency stop switch. Also,
for other kinds of systems, similar mechanical switches must be
provided to ensure safe operation of those systems.
