CPC H04L 12/40039 (2013.01) [G05G 9/047 (2013.01); H01H 25/04 (2013.01)] | 7 Claims |
1. A multiplexer switching device comprising:
a first data network comprising a plurality of normally open (NO) contacts; and
a second data network comprising a plurality of normally closed (NC) contacts; wherein:
said first data network is connected to said second data network via a common DC voltage link;
each of said NO contacts is electrically connected to a respective one of said NC contacts;
the common DC voltage link provides DC voltage to both of the first and second data networks simultaneously;
each of the individual NC and NO contacts is connected to and paired with a resistor R, wherein said resistors have values that are selected so that equivalent impedance is specific to each configuration case of contact activations, and
said multiplexer switching device is mountable in a side stick for a helicopter;
wherein said switching device is a four-direction switching device.
