A mounting structure of a roof duct in an air conditioner which comprises a top surface of the roof duct having an air diffuser and formed with a grooved recess along the longitudinal direction of the roof duct, a trough-shaped reinforcement mounted at both ends thereof on an automotive body engaged with the grooved recess, a swelled part partly swelled on the bottom of the reinforcement and formed on the bottom in reverse direction to the grooved recess, and a wire harness connected to a control switch and inserted into the space formed between the bottom of the grooved recess and the swelled part of the reinforcement. Thus, this mounting structure can obtain a passage of a wire harness out of the roof duct, thereby reducing the resistance of ventilation of air through the roof duct. Further, this mounting structure can use a reinforcement as a fixture of a wire harness and a protector, thereby reducing the abnormal noise from the roof duct, can reduce the number and weight of components to be mounted in the roof duct and can facilitate the mounting of the roof duct on the roof.

A button-less push switch board including a plurality of push switches which comprises an insulator plate having a plurality of penetrating holes, a transparent flexible cover sheet overlying the main surface of the insulator sheet and having identification marks printed thereon to indicate the positions and functions of the switches, and a printed circuit plate on the reverse surface of the insulator plate and having fixed contacts formed thereon. A transparent block is disposed in each hole of the insulator plate and is urged towards the cover plate by elastic members supported thereon. Each elastic member is of cup-like shape and has a movable contact corresponding to a pair of fixed contacts on the printed circuit plate. A lamp or a light emitting diode is disposed in each hole of the insulator plate and is mounted on the printed circuit. Each fixed contact and each lamp or light emitting diode are connected to an external control circuit.

An air conditioner system for sensing and controlling the temperature in the compartment of an automotive vehicle to an established desired temperature includes an over-correction means whereby the vehicle compartment temperature is temporarily increased to exceed the desired temperature and the temperature rise is terminated after the sensed temperature has attained or nearly attained the desired temperature. When the sensed temperature rises so that the difference between it and the desired temperature exceeds a reference value, the corresponding correction signal is generated and correction is applied repeatedly so as to make the difference less than the reference value and thereby to attain the desired compartment temperature.
