ABSTRACT:
A power selector assembly for a loudspeaker includes in one embodiment an audio transformer upon which a printed circuit board (PCB) is mounted via connector strips having pins for both securing the PCB to the transformer, and for individually electrically connecting foil contacts of the PCB to the multi-tapped primary and the secondary windings of the transformer. The transformer is mounted within a housing. An electrical wiper contact is resiliently mounted between the PCB and a knob retained in an access hole through the housing, for permitting the knob to be rotated for positioning the wiper contact to selectively electrically connect a foil terminal receiving an input signal to one of a plurality of contact foils of the PCB, for connecting the input signal to one of the taps of the primary winding associated with a desired power level. Other electrical connections on the printed circuit board provide for connecting a loudspeaker to the secondary winding. In another embodiment, only the secondary winding of the transformer is multitapped, and the power selector switching assembly is configured for permitting the knob to be rotated for selectively connecting one of the taps of the secondary winding to a load, for controlling the power applied to the load.
