What's the term for the 1/8" (3.5mm) DC jack on Electro Harmonix?

I don't mean mini phono. It's a TS jack that has 3 lugs and breaks the connection of one when plugged in rather than making a connection. It's perfect for disconnecting a battery and keeping Boss style plugs from being used. I want to get a few more for some -9v builds.

Thank you.
