Abstract
The present invention relates to a high-reliability vehicle mounted device control apparatus capable of making a decision about functions of switch units with a simple structure and at a high processing speed and a low cost. Each of the switch units comprises a circuit substrate having a required circuit pattern formed to include a plurality of pairs of short-circuiting possible land portions, and a switch mounted on the circuit substrate so that any one of the plurality of pairs of land portions are short-circuited selectively to set a switching function inherent to that switch unit. Any one selected from the switch units is mounted in one of the unit mounting sections, and the switch of that switch unit is turned on. A switch unit decision section constituting a control section detects the land portions short-circuited to automatically make a decision about the kind of a switching function of the mounted switch unit.
