Dual DCC Signal Controller for Dapol Semaphore Signals.
The SC3 controls one or two Dapol N or OO gauge motorised semaphore signals by DCC. Each signal can be given a separate DCC address with their position controlled by the SC3. The signals connect directly using their wires and no modification or power supply is required.
This unit can also be connected to the Mimic switches designed by Train Tech.
