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 neither the infamous YLOD
  • Eject led, this is the only led not controlled by syscon, the line goes to the bluray drive, so is the bluray drive who decides when is lighted on
  • White backlight leds, this was added for PS3 slim models with the new design of the 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

• 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
  • Boardmodel naming seems thus first letter of SKU motherboard (C=COK, D=DYN, K=KTE, M=MSX/MPX) + "SW-001" (with the exception of HSW-001)

• Notes:
  • Contour leds - the leds are hidden close to the usb port under the main touch panel. none of the hidden Leds are grounded out but, always receives V+ even when in standby ( red light standby ) reason is unknown and has been found even back on first gen models.
  • Compatibility with other ps3 models - this board will work with out back white, hidden, eject led, and 10th gnd pin on a 300X model full power eject and red and green led, A KSW-001 Will not work on a 200X model (dsw-001 slot).

Contour backlight in PS3 2000 Series boards

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

Light rays bouncing surfaces, and light reactive materials

Switch board PS3 2000 series
Light rays schematic in contour leds

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)
