HSW-001
Description
Serial numbers: 1-881-946-11 (Unknown manufacturer), 1-881-946-21 (Produced by Foxconn)
HSW-001 is a switch board firstly used in Slim CECH-21xx (with SUR-001 motherboard), and later in CECH-25xx models (with JTP-001 or JSD-001 motherboards)
All this motherboards has the same switch board connector and pinout, so HSW-001 is compatible with all them.

Blue led - | Connects to blue LED located next to the eject switch, with a currentlimitor resistor of 560 Ω |
| 10 | GND | GND | GND | Ground |
How it works
All LED's on the switch board are turned on/off either by syscon or by the BD drive by using an intermediary transistor that drives the LED ground pin (and the other pin of the LED's is connected permanently to the 5 volts standby line present in the switch board at all times). 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
When Power and/or Eject switches are pressed the correlating syscon pins are pulled down (grounded)
- Contour LED's
- Are separated from the rest of the board by a transistor, the transistor is activated by a volts signal from PIN1 of the connector, but the motherboard doesnt send this signal, see Discussion
- There are several ways to re-enable the contour LED's. And there are solder points without components to duplicate this subcircuit to add another 2 LEDs more for a total of 4
