To Do:
Shown is the panel as supplied by PC Flights assembled with PC Flights supplied toggle switche.
This panel is the correct size although the width between bolt holes seems to be a bit shy of the DZUS standard (as I understand it). This hole spacing allows the PC Flights DZUS replica bolts to fit without interference with bolts on an adjacent panel.
The challenge is to backlight this panel as well as to provide connection to simulator hardware.

Isometric view of completed unit.

  • Get 2 DZUS replica bolts (PC Flights and Sismo both supply them).
  • Fabricate 1 new circuit board:
    Circuit board for lighting the voice-rec-sw panel. This board will use surface mount LEDs and mount within the acrylic backing panel. This board also has connectors for the toggle switch.
  • Add caps to switch handle (see note below).
  • Solder LED's and resistors to LED board.
  • Solder the Connectors to this same board.
  • Drill 2 holes in the circuit board to clear the 2 front panel screws.

    Here is the end result

    Circuit board with LED's and resistors mounted. The parts are not perfectly lined up, but it's what you get when hand-soldering SMD parts.

    Mount the circuit board and switch to the voice-rec-sw backplate.

    Switch Caps
    Lowes has a product called "White Screw Protectors" for a 1/4" screw (Hillman # 881038). These protectors fit nicely on the handle of a toggle switch although you will need to add a small cylinder of heat-shrink tubing to the narrow part of the switch shaft.

    Surface Mounting
    Most of the units use CREE CLM1C-WKW-CWBXA453. I wanted 2400mcd brightness, 4500-5650K color temperature, 20ma.
    For a 12V supply, I use 2200 ohm resistors when driving 3 LEDs in a string or 3600 ohm for 2 LEDs
