Circuit arrangement for controlling interior lighting in motor vehicle has transistor, diode whereby circuit arrangement interconnects control signal applying to the input depending upon switching signal applying to terminal to output

摘要

Circuit arrangement comprises a transistor (T1), a diode (D2) and two resistances (R1,R3). The circuit arrangement interconnects a control signal applying to the input (1) depending upon a switching signal applying to the terminal (4) to an output (5). The base of the transistor is connected with the input by the resistance. The emitter of the transistor is connected with the terminal by the diode. The emitter of the transistor is also connected with a terminal (3), by a resistance, to supply a supply voltage. The collector of the transistor is connected with the output.
