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.

Abstract: In a switch, the speed at which contacts are separated from each other is increased without depending on the speed at which an operating member is operated, so that an arc is prevented from being generated, to prevent the operating member to be deformed by heat generation and prevent the durability of the switch to be decreased due to the abrasion of the contacts. A movable contact member having movable contacts at both its ends is swingably supported with a common fixed contact projecting upward and serving as a fulcrum. A leaf spring is fixed to a slider. The leaf spring has a portion projecting in a U shape. The U-shaped portion is engaged with the center of the movable contact member. When the slider is moved, the U-shaped portion is distorted in the transverse direction. When the slider is further moved, the U-shaped portion gets beyond the fulcrum, so that the movable contact is rapidly separated from a normally open fixed contact.

Abstract: A selective switch includes a switch housing, and a button cap with two opposite side portions. A contact assembly includes first, second and third conductive members which are all fixed in the switch housing. A helical spring is mounted in the switch housing, and has an outer end portion to support the button cap thereon and an inner end portion adjacent to the contact assembly. A flexible mandrel has an inner end portion and an outer end portion which is integrally formed with the outer end portion of the helical spring. The helical spring extends around the flexible mandrel.

Abstract: An electrical switch includes a rocker-type actuator adapted to be pivoted between first and second positions within a housing in order to close and open switch contacts. The actuator slidably supports a latch which normally engages the housing to prevent the actuator from being pivoted to its switch-closed position. By pulling on the latch and then lifting on the actuator, the actuator may be pivoted to its switch-closed position; the two-step operation protecting against accidental actuation of the switch. The switch housing is mounted with a snap fit in an opening iun a panel. A lug on the housing engages the underside of the panel to prevent the switch from being pulled out of the opening in the event a heavy lifting force is applied to the actuator without first releasing the latch. One switch contact is adapted to pivot and slide on a fulcrum which is laterally offset from the pivot axis of the actuator in order to delay opening of the switch relative to the position of the actuator.
