[IxDA Discuss] This is the ultimate power switch WAS: Power icon

[Morten Hjerde]

It is of course the venerable Illuminated
rocker<http://www.cnet.co.uk/i/c/blg/cat/blog/off_switches/3.jpg>(<

All software designs should try to carry over as many as possible of its
excellent qualities:

   - Two distinct states
   - It is immediately clear if it is "on" or "off"
   - Audible and tactile feedback
   - Clear and understandable marking

Plus it adheres to standards. The off state is the "down" position and the
symbols are the IEC/IEEE standard so its usable globally.

Aye or nay?
