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