SIGNAL TRANSMITTER

摘要

A signal transmitter contains at least one first luminous element, at least one second luminous element and an interface for connecting the signal transmitter to a signal box. A drive device is connected between the interface and the at least two luminous elements and the drive device is configured in such a way that, in the case of a switch-on signal coming from the signal box for the second luminous element, the drive device controls the activation of the luminous element depending on the signaling state of the first luminous element.
