[0003] The main disadvantage of this controller is: when the alarm function is activated, the turn indication function loses its function immediately
However, this kind of controller is still a mechanical switch controller, which not only has a large volume, but also has a large current passing through the steering and alarm switches during operation, which shortens its service life; The power of the indicator light is directly related to

The integral controller for alarm lamp and turning lamp of automobile includes the turning switch, the alarm switch and control module. The control module inside a casing is connected electrically to the turning switch and the alarm switch, and includes one left turning lamp control circuit, one right turning lamp control circuit, one flasher relay circuit and one power source filtering circuit to power the foregoing circuits. The flasher relay circuit has output signal fed to the left turning lamp control circuit and the right turning lamp control circuit; and both the left turning lamp control circuit and the right turning lamp control circuit are logical operation circuits and have output connected to the left turning lamp or the right turning lamp. The present invention has capacity of convenient fast turning operation, long service life and other advantages.
Description
Technical field: [0001] The invention relates to an automobile indicator light controller, in particular to an integrated controller which simultaneously controls the automobile alarm and the turn indicator light. Background technique: [0002] In the prior art, automobile alarm and turn indicator controllers are generally mechanical switch controllers, which have many deficiencies. Referring to Fig. 1, the circuit operation principle of the existing automobile alarm and turn indicator controller is shown in the figure, when the alarm switch S3 is not pressed, between B1 and B2, between C1 and C2, and between D1 and D2 are all disconnected. At this time, if the handle 31 (i.e., the steering switch) is in the middle position, Z, L, and R are all disconnected, and the steering indicator light has no power supply and does not flash; if the steering handle 31 is pulled down (turning left), Z and L are connected , the front left and rear left turn indicator lights are connected ...
