Cost savings and a reduction in assembly errors thanks to RAFIX FS. The PCB switching elements are soldered on to the PCB. There are two options when it comes to illuminating the actuators: A 3 mm THT LED that is plugged into the switching element base and is soldered on to the PCB together with the switching element. An SMT LED that is positioned separately. Its light is transported with the light conductor and is distributed across the whole of the bezel.
