Magnetic latching coaxial switch

A remotely controlled switch comprising:

• an input terminal;
• a plurality of output terminals;
• switching means for connecting said input terminal separately to each output terminal;
• controller means for establishing a connection via said switching means from said input terminal to a selected output terminal;
• said controller means including latching means including a permanent magnet providing a magnetic field for retaining the connection from the input terminal to the selected output terminal pending a change by the controller means, and a magnetic circuit operable between two states as determined by electrical signals including a coil and a rocker arm,
• said coil being responsive to said electrical signals to provide magnetic forces for use in conjunction with said magnetic field to cause deflection of the rocker arm,
• said magnetic field providing a latching force for the rocker arm between electrical signals, and
• coupling means located between the rocker arm and the switching means to control the position of the switching means.

A remotely controlled switch comprising:

• an input terminal and a plurality of output terminals including means for coupling to RF transmission devices,
• switching means for connecting the input terminal separately to each output terminal and enabling the completion of connections between RF transmission devices,
• controller means for establishing a connection via said switching means from the input terminal to a selected output terminal;
• said controller means including latching means including a permanent magnet providing a magnetic field for retaining the connection from the input terminal to the selected output terminal pending a change by the controller means, and a magnetic circuit operable between two states as determined by electrical signals including a coil and a rocker arm, said coil being responsive to said electrical signals to provide magnetic forces for use in conjunction with said magnetic field to cause deflection of the rocker arm, said magnetic field providing a latching force for the rocker arm between electrical signals, and coupling means located between the rocker arm and the switching means to control the position of the switching means.

A remotely controlled latching switch comprising:

• an input terminal,
• a plurality of output terminals,
• switching means for connecting the input terminal separately to each output terminal,
• controller means for establishing a connection via said switching means from the input terminal to any one of said output terminals,
• said controller means including a magnetic circuit operable between two states as determined by electrical signals, latching means for retaining the connection from the input terminal to the selected output terminal pending a change by the controller means, and a mechanical linkage to the switching means, including a rocker arm, an elongated slot in said rocker arm, a pin, and a slot in said pin, said elongated slot engaging the slot in said pin, whereby the slot in the pin may slide in the elongated slot of the rocker arm to enable desired movement of the switching means.

A switching device comprising:

• a first terminal,
• a first and a second additional terminal,
• connector means for connecting the first terminal alternately to the first and second additional terminals,
• controller means including a mechanical linkage for controlling said connector means,
• said contoller means including means for generating a magnetic field,
• said means for generating a magnetic field enabling changes in the connection of the connector means between the additional terminals, and
• a permanent magnet,
• said permanent magnet serving to latch the mechanical linkage of the controller means to maintain the connector means coupled to either the first or the second additional terminal.

An electrically controlled switch comprising an input terminal,

• first and second output terminals,
• switching means including a first contact end permanently secured to said input terminal and a second contact end switchable between the first and second output terminals,
• electrically actuated controller means having a mechanical linkage for moving the second contact end of the switching means to complete a connection with the first or second output terminal, and
• latching means for latching the mechanical linkage and thereby holding said second contact end in contact with either output terminal after the controller means is actuated.
