摘要： A multiple speaker loudspeaker of the type comprising a larger speaker including a larger frame and at least one smaller speaker including a smaller speaker support structure is provided with first and second rigid power conductors which are rigidly mounted both to the larger frame and to the smaller speaker support structure such that the power conductors support the smaller speaker permanently in place in front of the larger speaker. These power conductors are electrically interconnected both to the smaller speaker and to power input terminals of the loudspeaker such that the first and second power conductors conduct electrical audio signals from the input terminals to the smaller speaker.

摘要： An index rotary switch includes a housing, stationary contact members, a rotor contact member, and a pushbutton-operated actuator device. The stationary contact members are disposed within the housing for defining an infinite number of alternately achieved on-and-off positions. The rotor contact member is disposed for rotation within the housing for wipingly engaging the stationary contact members. The rotor contact member is formed with a rectangularly-shaped flat portion and a plurality of resilient L-shaped arms extending downwardly from respective edges thereof. The L-shaped arms have arcuate-shaped contacts formed upon their free ends so as to wipingly engage the stationary contacts. The actuator device is disposed within the housing and is operatively connected to the rotor contact member for sequentially rotating the rotor contact member so that the arcuate-shaped contacts alternately index with respect to the on-and-off positions upon successive actuations of the actuator device.

摘要： An electrical switching device for door actuated operation especially configured for conversion between grounded and non-grounded operation is disclosed. The device includes a housing including a stationary contact and a moveable contact. The moveable contact is actuated by a door operated actuator which moveable contact makes and breaks contact with the fixed contact and completes a circuit to ground through the housing. The moveable contact and fixed contact are configured to receive and cooperate with an insulation member insertable between the two contacts and an additional contact member insertable between the insulation member and the moveable contact to convert the switch to non-grounded operation.

摘要： A loudspeaker allowing snap-together assembly and extensive use of plastic is provided. The magnet is substantially enclosed between a molded plastic basket and a threaded cap, and the magnet clamps the spider which centers the voice coil in place. The base of the cone of the loudspeaker is frictionally held between the basket and a clamping ring. The electrical connection between the voice coil and the input terminals includes conductive strips formed of conductive ink upon the spider. The conductive strips are soldered to the leads of the voice coil and are joined to the input terminals by pressure contacts of a terminal strap which is snapped in place in the plastic basket. A grille subassembly for mounting within the basket of the loudspeaker is provided to permit snap-together assembly of multiple loudspeaker systems. The electrical connections between the loudspeakers of the multiple loudspeaker system are made at final assembly by the terminal strap. A novel grille and support arrangement for the smaller speakers, as well as a novel positioning ring for the magnet assembly, are also disclosed.

摘要： A loudspeaker allowing snap-together assembly and extensive use of plastic is provided. The magnet is substantially enclosed between a molded plastic basket and a first lock member. Deformable fins aid in centering the magnet and in maintaining an annular gap between elements of the magnet. The base of the cone of the loudspeaker is frictionally held between the basket and a second lock member. The electrical connection between the voice coil and the input terminals includes conductive strips formed of conductive ink upon a centering disc. The conductive strips are soldered to the leads of the voice coil and are joined to the input terminals by pressure contacts of a terminal module added at final assembly. A bridge subassembly for mounting within the basket of the loudspeaker is provided to permit snap-together assembly of multiple loadspeaker systems. The electrical connections between the loudspeakers of the multiple loudspeaker system are made at final assembly by the terminal module.
