You can switch the wiring by just pushing instead of pinching a knob to prevent an error like volume-tone selection.
No need to pinch a knob on switching, so you can even use hard-to-grip knobs like bell, hat or sombrero.
You can switch the wiring while holding a pick.
“When pushed down, the Selector interacts with the bottom 4 lugs (B-C-E-F).” B connects to C E connects to F “When pushed (again) to pop up, so it does with the top 4 lugs (A-B-D-E).” B connects to A E connects to D. As you can see, B and E stay connected.
As four variations (250K A type, 250K B type, 500K A type and 500K B type) are available, you can connect and wire any pickups. A type : Audio taper B type : Linear taper
