Hi Ben,
Thank you for the link to the opened 12V switch control device. It is very
informative. I measured, without openening, the resistance of the coil (if I
remember correctly it was about 55Ohms) but I couldn't really conclude if there
was a diode built-in to protect the circuitry of being baked when the current
to the coils is stopped. It seems that there is no diode in the switch device.
(It might be than in the control unit for the switch... or just LEGO skipped
it at all).
Do you know if the led's in the stop/go 2x3 brick contain a current limitting
resistor. I didn't have time to check this my self...
Guido
