Abstract
A reed switch mounted within an electrically conductive tubular member so as to form a coaxial center conductor, the tubular member and center conductor forming a coaxial line with a predetermined impedance therebetween. This reed switch and tubular member are mounted within a coil to form a reed relay.
Claims13
Apparatus for mounting a reed switch in conjunction with microstrip circuitry having an active plane and a ground plane on a substrate, said apparatus comprising:
- (a) an elongated tubularly shaped, electrically conductive member with a longitudinal axis and designed to receive a reed switch axially therein so as to form a substantially coaxial center conductor therethrough, the dimensions of said tubular member being formed to provide an impedance substantially matching the microstrip circuitry;
- (b) grounding means affixed to said tubular member adjacent each end thereof;
- and
- (c) said substrate defining an opening therethrough for receiving said tubular member therein with the longitudinal axis thereof lying approximately in the active plane of the microstrip circuitry and said grounding means positioned in contact with the ground plane.

Mounting apparatus for providing a reed switch with a predetermined impedance, said apparatus comprising:
- (a) a reed switch with two longitudinally extending connecting leads;
- and
- (b) an elongated tubularly shaped, electrically conductive member with a longitudinal axis having said reed switch mounted axially therein so as to form a substantially coaxial center conductor therethrough, the dimension of said tubular member being formed to substantially provide the predetermined impedance between the conecting leads of said reed switch and said tubular member.
