The Connecting Plugs From Schützinger Have Already Been Used for Breakout Boxes for Many Years. as the Number Of Contact Points Rises, So Too Did the Space Requirement. Schützinger Has Now Turned the Principle On Its Head! Instead Of Two Sockets that Are Connected By One Connecting Plug with Two Contact Pins, the Two Contacts Now Occupy a Coaxial Position in the Connecting Socket Brbu 7924 L and Are Connected By a Connecting Plug Brst 7922 Ni with Two Coaxial Spring Cages. that Reduces the Need for Space By Half!
