Switch usage for routing ethernet-based aircraft data buses in avionics systems
First Claim
1. System for point-to-point manual routing of data between avionics equipment comprising:
- first structure for point-to-point routing high speed data from first avionics equipment on board an aircraft to second avionics equipment on board said aircraft through a manually-operable electromechanical switch having at least first and second manually-settable positions and associated electrical contacts; and
second structure coupled to the first structure for manually changing position of the electromechanical switch to instead point-to-point route said high speed data from the first avionics equipment to third avionics equipment on board said aircraft and different from said second avionics equipment,wherein the electromechanical switch connects said high speed data point-to-point from said first equipment to said second or third equipment through said manually-settable electromechanical switch electrical contacts at a flow rate in excess of 1 mbits/second.

Abstract
Switches for Ethernet-based aircraft data buses in avionics systems provide manual means (through human interaction) to route the information transmitted on avionics system high speed data buses. For instance, the information path can be selected according to crew or maintenance people intentions. Considering a point-to-point databus connection between two pieces of equipment, adding an appropriate switch in the connection between those two pieces of equipment can allow one or more pieces of equipment to be connected to the other terminals of the switch. Therefore, depending on switch position, it is possible to establish a connection between those two or more selected pieces of equipment, where other equipment connected to open terminals may remain without access to the data bus.
