Abstract (en)
A switch module between a railway signal box and a light emitting diode (LED) signal has a relay (H) with two switch conditions, and a signal box secondary wire (NF) inlet that is only linked to the LED signal input (La) when the relay is in a first condition. The signal box has a further main input wire (HF) that is only linked to the LED signal input (La) when the relay is in the second condition. In the second relay condition the secondary wire input (NF) is linked with the signal box return conductor input (RL) via a resistance (R3).
