Carling Technologies offers the N-Series addressable rocker switch, featuring the look and feel of a traditional electro-mechanical control coupled with a built-in printed circuit board to provide an 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, which are then assigned to the specific functions the switch is controlling. Each switch is connected to an ECU, and application software is written to recognize the switch IDs to determine what load is being controlled and the selected actuator position. Wiring harnesses are simplified, and specific loads can be controlled from any location within a vehicle cab, providing design flexibility. Other features include an operating temperature range of -40 to +85°C (-40 to +185ºF).
