The present invention patent refers to improvements introduced in electrical control systems for angular adjustment of the reflecting element of external rear-view sets utilised in automotive road vehicles. This new system expedites and simplifies the installation work, and does not require the connecting of wires for the control of its various functions. In broad lines, the new features consist of a control system, which possesses inside the rear-view set casing (3), a small four-channel electromagnetic wave receiver (5), whose circuit board is connected to a micro-switch set (6), which eventually could be incorporated on the circuit board itself, and each micro-switch activates one of the micro-motors (4), the control signal is issued by a small electromagnetic wave transmitter (7) of reduced capacity, attached to the instrument panel of the vehicle. This transmitter possesses a circuit board to which the switches or keys (8) that are operated by the motorist are connected, and each switch/key activates a transmitter channel (7) that corresponds to the respective receiver channels (5). |
