Coaxial switch for high frequency signals

A switch for use in wide band systems handling high frequency signals, comprising:

• a hollow body which is electrically conductive,
• first, second and third coaxial terminals on said body located in spaced relation,
• each of said terminals having outer contact portions connected to said body and also having inner contacts projecting into said body, the inner contacts of said second and third terminals being on opposite sides of and equally spaced from the inner contact of said first terminal,
• a rotor of electrically non-conductive material,
• a movable contact of arcuate shape carried on the circumference of said rotor and of a length to connect the inner contact of said first terminal alternatively with the inner contacts of either said second or third terminal,
• means rotatably supporting said rotor in said body for arcuate movement of said movable contact to alternative positions connecting the inner contacts of either the second or third terminal to the inner contact of the first terminal,
• means connected to said rotor and extending externally of said body for moving said rotor between said positions, and
• partition means integral with said body and extending inwardly from between said terminals to adjacent the circumference of said rotor to form barriers to radiation between the exposed and unconnected inner contacts.
