A selector establishes connections
A conventional three-way guitar toggle selects one pickup, the other pickup or both. In the supported two-volume circuit, the selector inputs come from the volume wipers; its output continues to jack TIP. The centre position joins both channels to that output.
This is a description of circuit function, not a universal physical pinout. Different toggle constructions can arrange solder tabs and ground contacts differently. Some switches present separate output contacts that must be joined as specified. Identify the exact part before copying a drawing.
Separate signal contacts from the frame
The pickup inputs and common output are signal connections. A frame, shield or designated ground lug has a different role. Attaching a signal wire to a ground contact can mute the instrument, while omitting a required shield connection can leave noise problems.
For a braided pickup lead, the core and braid do different jobs. Colour-coded four-conductor pickups add coil starts, finishes and a separate shield where provided. Use the maker’s conductor convention to establish which lead is hot in the chosen series arrangement; colour alone is not a universal electrical identity.
Map the switch with continuity checks
With the switch disconnected from the rest of the circuit, compare continuity between candidate inputs and outputs in each position. Record which input connects in the first position, which connects in the other end position and which contacts join in the centre. Verify the ground contact separately.
An in-circuit meter can see paths through pickups and pots, so a reading may not identify a switch contact cleanly. Isolate the switch when necessary. Establish the viewing orientation as well: a rear view and an installed player view can reverse apparent directions.
Connect the functions, then route the wires
In the supported Les Paul reference, each volume output is lug 2. Those outputs go to the selector inputs, and the selector common goes to jack TIP. The jack sleeve connects to the return network. Follow the complete configured reference for both the signal and shielding paths.
Physical wire routes can differ while the electrical connection remains equivalent. The important questions are which terminals are joined, which contacts close and whether an unintended short exists. Leave clearance for the switch movement, cavity cover and exposed solder tabs.
Distinguish a contact fault from a control interaction
Intermittent output when the switch moves can point to contact condition or a stressed joint, but inspect the rest of the path before replacing the part. No output in one position can come from a disconnected pickup input, a channel fault or an incorrectly identified common.
Both pickups going silent when one volume reaches zero is consistent with the conventional dependent-volume arrangement. It should not automatically be blamed on the toggle. Test single-pickup positions and the shared output path to distinguish these cases.
Use a supported reference rather than inventing a pinout
The Generator supplies a functional switch reference for its supported configurations. Compare it with the manufacturer’s physical contact drawing; it is not a claim that every aftermarket switch shares one mounting or terminal pattern. Signal Forge can help trace the selected path.
After assembly, inspect and check continuity before reconnecting equipment. A consistent contact map and labelled terminal functions are more useful than matching an unverified internet photograph. If the part does not match the reference, obtain its documentation instead of guessing.
