The COO2 switch can be applicable to all Rokuhan Turnouts. The RC-01, RC-02, and RC-03 can be used as a power source. You can connect Rokuhan AC adapter (sold separately) to use as a standalone or connect Rokuhan A010 AC power cable, to use AC power (AC16V) from another brand power pack. Additionally you can snap together multiple C002 switches and control many independent remote turnouts from one location.
