Long story short I am cobbling together a military field telephone and a commercial intercom system to make an intercom system between my workshop and living area. The field phone is one used in the Battlestar Galactica series and requires a switchboard to use. I'm gutting one of the field phones and placing one of the intercom phones into it. The intercom system is the Aiphone AT-406 http://www.aiphone.com/home/assets/Uploads/downloads/documents/products/instructions/AT-406%20Instr.pdf

Problems I ran into are two of the switches used in the intercom system. The call send button located on the face of the intercom is an Omron D2F single pull double throw microswitch. I would like to remove this switch and hook it to one of the field phone keypad buttons but have yet to figure out how to power the other leg.

The other switch is the cradle switch, an SPUJ194500 http://www.alps.com/prod/info/E/HTML/Switch/Push/SPUJ/SPUJ194500.html It's a 4-pole switch with 12 pins soldered to the PCB. My intent was to remove this switch and use a reed switch in the handset cradle to end the call. The field phone had a reed switch in place. Not sure if I broke the switch or if it was already damaged. The original reed looked to be a transfer type.

Any suggestions? I have zero electrical training but am doing my best to learn as I go. Any advice is greatly appreciated!

 

Looks like I need to look at a relay to replace the microswitch on the call button. I should be able to use a single key on the otherwise unused field phone keypad to actuate the relay and send the call signal.
