An excellent device, to be able to activate Dapols servo operated signals via normal DCC control simultaneously in conjunction with turnouts obviates the need for additional wiring and switching and is a significant benefit. Used in this way requires the supplied switches to be de-soldered from the connecting wires, but should pose no problem to the experienced modeller.

The 4A-001-002 Servo signal controller, makes adding signals to the layout nice nd easy. They work well Train Controller software and I'm delighted with the results.
Great Job Team!
