Switchable attenuator assembly and method of assembling same

摘要

A switchable attenuator includes a split housing assembly formed of interlocking cover and support members. A plurality of rocker arms are mounted for pivotable movement between the cover and the support members and each rocker arm has lugs formed on opposite ends thereof which receive respective ones of a pair of shorting bars. Electrical circuit connectors, coupled to an attenuator circuit mounted adjacent to the support member, are aligned in pairs with each pair being positioned to receive a respective one of the pair of shorting bars associated with each rocker arm. The rocker arms are selectively pivoted to cause the shorting bars to move into and out of engagement with the electrical circuit connectors aligned therewith to selectively provide attenuation of different magnitudes to an external circuit.
