Electronic Switch for Modellers

Switching systems in models often suffer from mechanical problems. This electronic replacement is much more reliable and offers a little bit extra!Remote-controlled models include many components that, because of their various shortcomings, need to be checked constantly. The scale of the problem is clear from the number of different add-on units that are available from the various manufacturers. Here we present an extremely useful circuit that replaces the (often rather temperamental) switching harness and which also offers a voltage-monitoring function with memory.
