The authorized sizes for the Green Start button (11 mm, 9 mm, and 6.6 mm) refer to the diameter
of the dome lens and do not reflect the total size of a manufactured Green Start button
subassembly.

implemented (illustration is not to scale)
The size of the Green Start button that should be implemented on a device is determined by the
device type. To determine the button sizes that can be implemented on a particular device, refer
to the hardware specification for that device.
For example, if you are preparing to manufacture a remote control for Windows Media Center,
refer to the Remote Control Specification for Windows Media Center Technologies to find out
which size Green Start button should be included on the remote control.

The keycap is manufactured in a clear material to better integrate with any device design and
color scheme. The keycap design includes an orientation feature to ensure that the Green Start
