Common Wiring Schemes Found in Antique Telephones
There are a few common wiring schemes found in antique telephones. Understanding these wiring schemes will help you read and interpret wiring diagrams more easily. Here are some of the most common wiring schemes:
Common Battery (CB) Wiring Scheme
The common battery wiring scheme was used in early telephones, where there was a battery at the central office that powered all the phones on the line. In this wiring scheme, the phone does not have its own power source, but instead relies on the power from the central office battery.
In a common battery wiring scheme, the phone has two wires that connect to the line (L1 and L2) and two wires that connect to the receiver (T1 and T2) and transmitter (R1 and R2).
Local Battery (LB) Wiring Scheme
The local battery wiring scheme was used in later telephones, where the phone had its own battery to power the transmitter and receiver. In this wiring scheme, the phone has four wires that connect to the line (L1, L2, T1, and T2) and two wires that connect to the battery (B1 and B2).
Manual Switchboard (MS) Wiring Scheme
The manual switchboard wiring scheme was used in early switchboard systems, where the operator manually connected the calls. In this wiring scheme, the phone has four wires that connect to the line (L1, L2, T1, and T2) and two wires that connect to the operator’s switchboard (SW1 and SW2).
How to Wire an Antique Telephone?
Wiring an antique telephone can be a daunting task, but with the right tools and instructions, anyone can do it. Here’s a step-by-step guide on how to wire an antique telephone:
Step 1: Gather the Necessary Tools
Before you start wiring your antique phone, it’s important to make sure you have all the necessary tools. Here’s what you’ll need:
- Soldering iron
- Solder
- Multimeter
- Wire strippers
- Small screwdrivers
- Wire cutters

Step 2: Disassemble the Phone
Before you can wire your antique phone, you’ll need to disassemble it. This will give you access to the various components that need to be wired.
When disassembling your phone, be sure to keep track of which screws and components go where. Taking pictures or making notes can be helpful in remembering how to reassemble the phone later.
Step 3: Clean the Components
Once you’ve disassembled your phone, you’ll want to clean the components. This will help ensure that they work properly and will also make it easier to solder the wires.
Clean the components with a soft cloth and a small amount of rubbing alcohol. Be careful not to get any alcohol on the wiring, as this can damage the insulation.
Step 4: Solder the Wires
Using the wiring diagram, solder the wires in the correct locations. Be sure to use the correct gauge wire for each connection.
When soldering the wires, be careful not to apply too much heat, as this can damage the components. Use a small amount of solder and try to make clean and neat connections.
Step 5: Test the Connections
Once you’ve soldered all the wires, use a multimeter to test the connections. This will help ensure that everything is wired correctly and will also help identify any problems.
If you find any issues, go back and double-check your wiring.
Step 6: Reassemble the Phone
Once you’ve tested the connections and made any necessary corrections, you can reassemble the phone. Be sure to put all the screws and components back in the correct locations.
