"All of our switches are available 4 ways. 

(1.)Manual switches are not pre-wired for the train to run from one end of the switch to the other. A switch is a good place to end a block, so you don't have to make a cut or use a fiber pin for insulating.

(2.) Manual pre- wired switches are solidly wired here at the factory so you can just drop them in and go. We sell Caboose Industries, (#208-S), ground throws, separately, if you want something to lock the points over.

(3.) Switches also come with the DZ1000 switch machines.  pre-wired, and installed ready to run. The dz-1000 snaps back and forth. It is lighted and can be thrown without power. Non-derailing is built in, but you need to run two wires, (typically under the table), to hook that feature up. Use 18 gauge wire between included controller and switch machine.

(4.) or the  DZ2500 switch machines,  also pre-wired, and installed ready to run.  Non derailing is built in, but you need to run two wires, (typically under the table), to hook that feature up. Use 18 gauge wire between included controller and switch machine. 

The new DZ-2500 Switch Machine offers slow speed switching from the push button, TMCC CAB-1 remote, or DCS remote with the AIU. Just provide accessory power and ground to your DZ-2500 and to the DZ-2502 Remote push button. Only one control wire is required to operate from the remote push button. Using a DZ-2001, you can create a DATA WIRE that you run from your Command Base to anywhere on your layout (this creates a “data wire buss”) and then connect the DZ-2500 to it using only a single wire. 
Compatible with GarGraves, Ross, Curtis, Atlas switches."
