Matte ABS Elevator Toggle



Current limiting resistors are often placed in series in the circuit to limit the amount of current in the branch to prevent excessive current from burning out the components in series. At the same time, the current limiting resistor can also function as a partial pressure.

The resistor RL is the load resistor, R is the voltage regulation resistor (also called the current limiting resistor), and D is the voltage regulator tube. According to the design principle of the voltage regulator circuit, when the input voltage is basically unchanged, the RL becomes small and flows through the RL. The current increases, but the current flowing through D decreases.


Reducing the load current, such as adding a current limiting resistor at one end of the LED, can reduce the current flowing through the LED and prevent damage to the LED.
