Abstract

The Advanced Pickup Switch is a lever-style switch that will allow any guitarist, with a minimal amount of technical skill, to alter the pickup wiring configuration of their electric guitar for altering the tonal choices available without the need to manually hard-wire each connection. The tonal alterations are effected via rotationally and axially displaceable multi-layer printed circuit board (PCB) discs that contain pre-determined tracings for specific pickup coil configurations. These are attached to the outboard sides of the switch with a single screw, thereby allowing for complex wiring alterations with the use of a screwdriver alone. The lateral movement of the switch and corresponding axial displacement of the PCB's allows for the expansion of the number of combinations without the use of a secondary switch. A robust two-pronged resilient detent arm cooperates with gearage for providing a switch with the tactile feedback that is familiar and comfortable to guitarists worldwide.

Dependent claims

A pickup switch assembly for use with an electric guitar configured to enable a user to selectively alter pickup signal output, the pickup switch assembly comprising:

an arm assembly, the arm assembly comprising a central hub structure and an arm structure, the central hub structure comprising a first hub half and a second hub half, the first hub half comprising a lower hub structure, the lower hub structure comprising a series of radially extending detent teeth, the arm structure comprising an arm, the arm extending in a direction opposite the lower hub structure;
a switch base plate, the switch base plate comprising opposed lower wall sections and an upper wall-spanning section, the upper wall-spanning section interconnecting the lower wall sections and comprising an arm-receiving aperture, the arm extending through the arm-receiving aperture, the arm configured to enable a guitarist to manually select switch positions;
first and second terminal base plate assemblies, said terminal base plate assemblies each comprising a terminal base plate and a series of terminals, the terminal base plates each being attached to the lower wall sections and comprising a hub-receiving aperture, the terminals extending radially from the terminal base plates, the hub-receiving apertures receiving the first and second hub halves, the first and second hub halves being axially displaceable as received by the hub-receiving apertures;
first and second circuit board assemblies, each circuit board assembly comprising current-conductive circuitry, the circuit board assemblies being attached to opposed ends of the first and second hub halves;
and
a resilient detent member, the detent member resiliently engaging the detent teeth of the lower hub structure configured to position the arm assembly in a select arm position, the arm being longitudinally and laterally positionable via the arm-receiving aperture and the first and second hub halves being rotatively and axially displaceable via longitudinal and lateral positions, the current-conductive circuitry being selectively engageable with the terminals via select arm assembly positions configured to enable signals to pass through said circuitry, said terminals being in electrical communication with a plurality of guitar-based pickups configured to direct signals from the guitar-based pickups through the terminals and select circuitry for further signal output, the switch assembly thus configured to enable a user to selectively alter pickup signal output.
