Just because the switches can accept 24 V doesn't mean you have
to run them at 24 V. The STG digital inputs have 10K pullup
resistors to +5V on the board. So, all the switch needs to do is
ground the input. Put the C contact to a ground terminal, and
then connect NO or NC as needed to get the right sense
polarity for the switch. (In EMC, you can also set the polarity
of the sense switches in the .ini file.)
