Abstract
Two lamp sockets (40, 42) on a wiring board (32) behind a switch assembly (18) have identical geometries. Each comprises a through-hole with a polarizing feature. Plural discrete contact pads (44, 46, 48, 50) are disposed on the board surface spaced apart around the margin of each through-hole. Plural discrete conductor traces (52, 54, 56, 58) are printed on the board surface to run from the respective contact pads. Each socket can accept either a first model (66) or a second model (68) 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 the locations of status indicator and nighttime illumination lamps.
