Monitoring switch position (prototype)

[faraway]

Switches may be equipped with a "Circuit Controller" such as U-5 or SC-100 to detect the switch blade position and close or open electric contacts. There are may different uses for those devices attached to the switch.
I have a specific question about "the other" equipment involved if a circuit controller is used to signal the position of a hand thrown switch in the mainline to the dispatcher.
The circuit controller is mounted to the switch. What else is installed at or close by the switch to transmit the information to the dispatcher far away?
I guess there is a box with a radio transmitter, an antenna and may be even a batterie pack as backup.

Can you point me to photos of that equipment (radio transmitter, antenna etc.)?

I do not ask for photos of the circuit controllers. I found them with tons of photos and information (e.g. <!-- m --><a class="postlink" href="http://www.raildev.com/sc100.html">http://www.raildev.com/sc100.html</a><!-- m -->) and plan to install them on two switches but I can not find a link to the local equipment triggered to send the information to the remote dispatcher.

Assuming you are talking about a hand throw circuit in ABS territory, there is no indication back to the dispatcher. All it does is cause the signals in the field to display a restrictive signal. The switch indicator is wired into the signal circuits.

Assuming you are talking about a hand throw circuit in CTC territory, there is no indication back to the dispatcher. All it does is cause a track occupancy indication (looks the same as a train sitting on the tracks or broken rail ) and the signals in the field to display a restrictive signal. The switch indicator is wired into the signal circuits.

Assuming you are talking about a hand throw circuit in "dark" PTC territory, there is no indication back to the dispatcher (other than described above). The switch will be wired into a local communication node that will communicate with the trains and PTC system by radio.
