DUAL FUNCTION LAMP SOCKET

摘要

Two lamp sockets on a wiring board behind a switch assembly have identical geometries. Each comprises a through-hole with a polarizing feature. Plural discrete contact pads are disposed on the board surface spaced apart around the margin of eac h through-hole. Plural discrete conductor traces are printed on the board surface to run fro m the respective contact pads. Each socket can accept either a first model or a second model of lamp assembly to make either socket a status indicator for the switch assembly or a nighttime illumination socket. A common wiring board can thereby serve different requirements for t he locations of status indicator and nighttime illumination lamps.
