Abstract
Disclosed is a vehicle equipment control device capable of effecting discrimination between a plurality of switch functions without involving any change in the circuit configuration. A plurality of detection switches 2 each of which has three driving pins 4a through 4c are mounted on a printed circuit board 1, and a plurality of key tops 6a through 6g are slidably supported by a housing 3 in correspondence with the detection switches 2. Provided on the lower surfaces of the key tops 6a through 6g are driving sections 9a through 9g each capable of simultaneously depressing arbitrary one or a plurality of driving pins 4a through 4c of the corresponding detection switch 2. When the driving pins 4a through 4c are selectively depressed by these driving sections 9a through 9g, each detection switch 2 outputs a switch signal peculiar to it, and discrimination between the control functions set for the key tops 6a through 6g is effected on the control circuit unit side by using this switch signal as a recognition signal.
