field telephone

[DELTA 9 1/2]

I own 4 field telephones from 1950 something.. Two of them Were from a police station in Munich, Germany. I use 2 D 1.3 volt battery's to power them. But id like to know how to hook one up the a Land Line phone..Eg a house phone.. I did some studying and found out I need a switch board to be able to get that done... So is there any was i can get one for cheap or maybe make one of my own??

PS there from cheaperthendirt.com Item #KEY-123

Moast telephones may be used as receiving telephones on regular network. (You have no dial to dial out)

You need a capacitor of 1-2 microfarad 200V a switch and a resistor.

Connect lik this:

C.O.----------------|--------capacitor-----Field telephone
.......................switch
|
......... resistor (approx 600 ohms)
|
---------------------|------------------------


---- and | are wires, .......... ar just to get space.
