[GreenKeys] Jack Selection for TTY equipment

[Cory Heisterkamp]

Evening Greenkeyers,

I wanted to solicit your advice with a project I have in mind. My current TTY arrangement Involves lots of exposed conductors, alligator clips and random wires. I'd like to tidy things up and build my loop supply into an enclosure with ammeter. Seeing as most of my equipment has quarter inch plugs, I'd like to build a series of jacks into the front of the unit to allow me to mix and match equipment. 

I'm wondering, are there certain types of jacks I should be on the lookout for? Won't the traditional style with nut bonded to sleeve create a shock hazard? Your thoughts?

Thanks, 
Cory
