MULTIPLE SWITCH CONTROL SYSTEM

摘要

A plurality of control switches (32, 43) are located in the hub (30) of a steering wheel (18) of a vehicle. The switches (32, 43) are connected to a remote control distribution terminal (CDT 41) by a single lead (36) connector. Actuation of each switch creates a switching voltage identifiable with that switch by a control circuit in the remote control distribution network. Reference voltages of predetermined values are spplied selectively to individual control circuits in a circuit network. A control circuit in the network identifies the actuation of its associated switch by comparing the value of the switch created voltage with a predetermined threshold voltage or reference and the effect of the switch created voltage value on the adjacent control circuit. Switch components are actuated for control of selected vehicle accessories.
