If a single switch control is to be used for multiple
units, please isolate each instrument. This can be
achieved by using a relay.
Warning
Ensure the cables and switch used exceed the
isolation voltage of the power supply. For example:
insulation tubes with a withstand voltage higher than
the power supply can be used.
