ABSTRACT:
A mechanical switch for switching microwave signals and the like from one coaxial-type connector to another includes a housing to which are mounted three coaxial-type connectors with their inward ends located adjacent first and second jumpers. The first jumper is supported at one end of a first slider which is movable between a closed position at which two connector ends are electrically connected by the first jumper and an isolated position at which the two connector ends are not electrically connected by the first jumper. The second jumper is supported at one end of a second slider which is movable between a closed position at which two others of the connector ends are electrically connected by the second jumper and an isolated position at which the two other connector ends are not electrically connected together by the second jumper. A spring moves the second slider to its isolated position when the first slider is moved to its closed position and visa versa. An armature member is pivotally supported about a pivot axis, and a magnetic drive means rotates the armature about its pivot axis such that the first end of the armature drives the first slider into its closed position when the armature is rotated in one direction and the second end of the armature drives the second slider into its closed position when the armature is rotated in an opposite direction.
