I wondered if anyone could advise please on the following:-
I am using a couple of home made 12v controllers (transistor) with an approximate currant rating of 1 amp. Solenoid type circuit breakers extracted from redundant Triang controllers are incorporated with these and work very well. I am now busy with a third controller and will need a further circuit breaker.... the construction of a scratch built item similar to the Triang wouldn't seem to be too difficult but I am interested in an alternative method and can remember reading somewhere that circuit protection can be achieved by using a standard 12v car light bulb built into the output line ; in the event of a short circuit on the track, or elsewhere , the current is directed through the bulb .....seems an excellent idea . I have tried the bulb in both series and parallel with negative results. Is there something here that I am overlooking?
Any help would be much appreciated.
