Multiple switch control system

摘要

A plurality of control switches are located in the hub of a steering wheel of a vehicle. The switches are connected to a remote control distribution terminal by a single lead 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 applied 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.
