Current Control (wiring diagram)

Activation by clicking on the consumer


The transistor reacts to a voltage drop to the LED, above and on the right, of approx. 0,6 Volt. This voltage drop is present if the current flow is given by the consumer. Therefore, the current-flow can be controlled by such a circuit. The LED below lights up if, through the small tension difference, the transistor becomes conductive. For possible controll-circuiting, the function of the LED below must be turned around through a NOT gate inverter.
A disadvantage of the circuit, is that the full tension of the current source is not available to the consumer. Therefore, is e.g., the circuit shown in Lighting system 2 more suitable.               Top of page               Index
