interesting points raised tonight. Think people are expressing their view on the link you posted re the rocker switch.
My understanding is that it was a prototype the student built during the Summer, and that a manufacturer has expressed an interest in making a purchase of 750k units.
So being a prototype would it not take some time for Arcolectric to actually move it forward into commercial production and for any sales to be achieved.
Has the company in fact moved this item into commercial production and achieved sales?
Perhaps you could give them a ring and discuss. (just a thought)
