NCE 524-154 Switch-It MK2 – DCC Turnout Controller

The NCE 524-154 Switch-It MK2 is a single-output DCC accessory decoder for controlling one twin-coil switch machine via DCC. Like the larger Switch8-MK2, it delivers a controlled pulse to throw the switch machine then cuts power — preventing coil burnout that occurs when standard decoders leave continuous current applied to a twin-coil motor. Install one Switch-It per turnout for modular, organized DCC switch machine control with clean screw-terminal wiring and standard DCC accessory addressing.
