PURPOSE:To enhance operational performance by arranging an illustrated display panel with blow-indication switches, which indicate the direction of ventilation for each mode and allowing each switch to show luminous display on its luminous body whose color varies according to the temperature, together with performing mode selection by operation of each switch in advance. CONSTITUTION:In an illustrated panel 1 in which the direction of ventilation for each mode is indicated by an arrow mark, each of blow indication switches 2 to 5, a ventilation switch 6 for taking in outdoor air, and a circulation switch 7 for circulation of indoor air are of the type whose contact is closed when the switch is depressed or touched. The surface of each of the switches 2 to 7 consists of a translucent material so hat the surface can be seen luminous owing to the luminous body lighted behind the surface. The luminous display on each of the switches 2 to 7 is performed by light emitting diodes (LED) which differ in their color; for example, 3 kinds of colors, LEDs 31 to 33. Each of LEDs 31 to 33 is lighted in order in accordance with the output from a temperature sensor 37 so that variation in temperature can be displayed by difference in coloration. |
