PROGRAMMABLE MATRIX CONTROLLER FOR CORRELATING ELECTRIC DEVICES IN A MOTOR VEHICLE WITH SWITCHES OF A SWITCH MODULE

摘要

A switch module (10) in an instrument panel of a motor vehicle contains multiple switch assemblies (16, 18, 20) connected by wiring (58, 60) to a controller. Multiple devices controlled by the switch assemblies (16, 18, 20 ) are connected by wiring (58, 60) to the controller. The controller has a programmed matrix correlating a switch input from each particular switch assembly (16, 18, 20) in the module (10) with a particular device to place each particular device under control of the corresponding switch assembly.
