Zusammenfassung:The utility model relates to a multi-circuit infrared remote control switch which is characterized in that a transmitting circuit is composed of an encoding integrated circuit IC1, transmitting circuits V1, V2 and an infrared transmitting tube ILED; a plurality of numerical control (AC) keys are respectively connected with the IC1; the numerical control (AC) keys switch on signals; the signals are encoded, locked and identified by the IC1, and then are output according to clock encoding; the signals are shaped and amplified by the V1 and the V2, and are modulated on the ILED to be transmitted; a receiving part is composed of an infrared receiver IC2, a demoding circuit IC3, a trigger storage circuit IC4, an execution change-over circuit and a power part; a plurality of remote-control manual change-over switches are arranged in the execution change-over circuit for user to conveniently select. The utility model has the advantages of strength electricity isolation, large receiving angle and free selection of manual operation and remote control.
