Abstract

PROBLEM TO BE SOLVED: To provide a switch device for an on-vehicle air cleaner wherein air cleanliness in a vehicle compartment and replacement time of a filter can be displayed. SOLUTION: A detection signal of air cleanliness in a vehicle compartment detected by a smoke sensor 22 is inputted in an ECU 23. Based on this detection signal, the ECU 23 changes a luminescent color of a two-color light emitting diode 7 by a previously memorized fixed processing program. When the air clealiness is high, it is changed to green and, when the air clealiness is low and air in the vehicle compartment if foul, it is changed to red. Further, the ECU 23 judges time of replacement of a filter of an air cleaner by a previously memorized fixed processing program. When the ECU judges that a time of replacement has come, a light emitting diode 8 is caused to emit light by a judgment signal.
