N-Series Addressable Rocker Switches
N-Series Rocker Switches
The N-Series Addressable Switch offers the look and feel of a traditional Electro-mechani-
cal control coupled with a built in PCB to provide customers with a flexible, cost effective
alternative to a CAN/LIN based switch. The N Series produces up to 144 individual switch
IDs by using a resistive ladder circuit. Different switch IDs are achieved by changing the
resistor values tied to individual loads. The individual loads can then be assigned to the
specific functions that the switch is controlling. Each switch is connected to an ECU and
the application software is written to recognize the switch IDs to determine which load is
being controlled as well as the selected actuator position. The end result means that
wiring harnesses are simplified and specific loads can now be controlled from any location
within a vehicle cab. Switch locations can now be rearranged without the need for a costly
and time consuming harness redesign, giving designers the ultimate in design flexibility.
The N-Series is available in lighted or non-lighted versions, with numerous choices of
actuators, colors, lighting circuits, and legend imprints.
