Uhlenbrock 63415 Polarity exchangerhe LocoNet switch module (63410) has a common positive pole for all consumers. Because of the connection of two motorized turnouts or light signals with common negative pole is not possible. Motorized switch machines require an operating voltage of alternating polarity. The solution provides the polarity exchanger. Attached to the LocoNet switch module, it provides four outputs with a common negative terminal available. Use it to connect two light signals. The polarity exchanger also a polarity change is given. Thus the connection of two motorized turnouts, nothing stands in the way. Up to four polarity exchanger fit on a LocoNet switch module.
