user13502: What is the simplest way to switch ON/OFF a 60v and 5 mA of current ? 
I don't want the common relays for arduinos as they make click noise.

user33209: // Following devices could be helpful in you case.

Power BJT as a switch (check datasheets if it comes on your required range).
Solid state relay is obviously, but cast is little high in this case.
