Abstract
Abstract A coaxial cable switch comprising a plurality of sealed reed, magnetically responsive switches serially connected in alternating directions which switches act as the inner signal path of a coaxial conductor. The outer coaxial conductor consists of a copper "corrugated" sheet within the adjacent and oppositely facing channels of which the individual switches are respectively positioned. The open sides of the channels are covered with metallic tape by means of a conductive adhesive and a single winding encircles the structure for the simultaneous operation of the reed springs.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
66 words
A coaxial cable switch construction comprising a conductive member formed to present a plurality of open-faced adjacent channels, the inner ones of said channels sharing common walls, a plurality of magnetically responsive relay means positioned respectively in said channels, means for electrically connecting alternating terminals of adjacent ones of said relay means to form a series combination, and electrically conductive means for closing said open-faced channels.
Claim 2
Dependent Claim
66 words
A coaxial cable switch construction comprising a conductive member formed to present a plurality of open-faced adjacent channels, the inner ones of said channels sharing common walls, a plurality of magnetically responsive relay means positioned respectively in said channels, means for electrically connecting alternating terminals of adjacent ones of said relay means to form a series combination, and electrically conductive means for closing said open-faced channels.
Claim 3
Dependent Claim
26 words
A coaxial switch construction as claimed in claim 1 in which said electrically conductive means comprises a flexible metallic tape adhesively bonded to said conductive member.
Claim 4
Dependent Claim
34 words
A coaxial switch construction as claimed in claim 1 in which said conductive member comprises a sheet formed so that the open faces of said adjacent channels alternate on opposite sides of said sheet.
Claim 5
Dependent Claim
30 words
A coaxial switch construction as claimed in claim 1 also comprising a winding means magnetically coupled to said plurality of relay means energizable for operating said plurality of relay means.
Claim 6
Dependent Claim
18 words
A coaxial switch construction as claimed in claim 4 in which said winding means encircles said conductive member.
