Abstract
An attenuator includes a housing defining an interior, a front, a rear, and a rotor mounted between front and rear for rotation within housing about an axis of the rotor. First electrical contacts are provided on the housing. Second electrical contacts are provided on the rotor. The rotor includes multiple printed conductor boards. Each PC board includes an electrically relatively non-conductive substrate. One side of each substrate provides conductive areas through which electrically attenuating elements of the attenuator are coupled together to form an attenuating network providing a selected level of attenuation. Electrical contact is made between the first electrical contacts and the electrically attenuating elements of the attenuator through the second electrical contacts.
