Switch boards

Description

The Switch board is a daughterboard where are located the input switches, and some leds for outputs and fireworks

• Switch board components
  • Switches: Power and Eject buttons
  • Green and Red leds, all switch board models have them, are needed to show the standby/poweron modes and the infamous YLOD
  • Eject led, this is the only led not controlled by syscon, the line goes to the bluray controller, so is the bluray controller who decides when is lighted on
  • White backlight leds, this was added for PS3 slim models with the new case design and the new pressure buttons (not touch sensitive)
  • Unknown subcircuit leds, this seems some kind of experiment that escaped the prototyping table and entered retail production, for some reason exists in some retail PS3 but seems deactivated and partially unpopulated
  • IC, there are a couple of "chips" only in the first model of the switch board, probably related with the touch sensitive feature and maybe others

• Switch board circuit overview (based on how HSW-001 works, this could be different for other switch board models)
  • When Power or Eject switches are pressed the correlating syscon pins are pulled down (grounded)
  • All LED's have its own resistor with a different value to control the current (thus light intensity) and one or more diodes to protect the circuit
  • The LED's on the switch board are turned on either by syscon (all them except one) or by the BD drive controller (only the eject blue led) by using an intermediary transistor
  • That transistors connects the LED ground pin to ground when the signal to turn them on is sent by syscon or by the BD drive controller (the other pin of the LED is connected permanently to the 5 volts standby line)

• Notes
  • Switch board model naming seems to follow the first letter of the first motherboard that used that switch board + the letters SW (acronym of switch)
  • CSW=COK, DSW=DYN, KSW=KTE, MSW=MSX (or MPX incase is older), PSW=PPX (or PQX incase is older), RSW=RTX
  • The only exception is HSW-001 (because doesnt exists a retail motherboard model starting with H... this opens speculations because maybe there is a non-retail prototype unknown motherboard in between DYN-001 and SUR-001 with a name starting with H)

Contour backlight in PS3 2000 Series boards

Switch board PS3 2000 series
Light rays schematic in contour leds

PS3 2000 series CECH-20xx (with Switch board DSW-001), CECH-21xx and CECH-25xx (with Switch board HSW-001) has been designed to have a lighted line all around the top edge of the Switch board

The plastic plate uses a "light reactive" material along the edge and in a squared hole in the corner allows the light to "transpass" it

The ligth rays "bounces" inside this material, and the first bouncing surface over the squared hole is a plane at 45 degrees angle. This first bounce aligns the light rays in paralell to the board, the next bounces happens all along the curved surface in horizontal

The reflection of this surfaces can be increased a bit with chrome stickers (or alluminium tape). The case has a plane border of 3,5mm x 17,7cm perfect to stick in it, this way the glue layer of the sticker is at the other side, but the case doesnt have the 45 degrees surface (it has a weird hole instead), you can use other colors for the sticker/s because the color is partially visible from outside (preferably lighter colors or one that matches your led/s color to enhance it)
