(***, - - -, ***) World Magnetics Company to the Rescue - Adaptive Sip & Puff Communications for Ham Radio

91-year-old Jack Orr rescued his good friend from a
debilitating stroke by giving him back a voice 
 

Press Release   3/01/2013

Since its original invention, Morse code has been a universal way to communicate messages around the world. First developed in 1836 as a code to transmit natural language between electrical telegraph systems, Morse code has become the most internationally recognized electrical coding system. Whilst the system has gone in and out of favor, most people still recognize the international code for emergencies, SOS (***,- - -,***).

Therefore, it was very fitting when World Magnetics Californian distributor, Frontline Management, was contacted by 91-year-old Jack Orr with an unusual SOS call, and they came to his aid. Jack has been a Ham Radio operator for over 40 years and communicates around the world with like-minded friends using Morse code. Recently, one of those friends in Washington had suffered a debilitating stroke and Jack was looking at a way to continue communication. He devised a system by which he could incorporate the proven World Magnetics pressure and vacuum switches into a sip and puff mechanism. The mechanism now allows Jack's friend to continue to communicate with Jack and other friends around the world without the use of his hands. With either a simple blow or suck on a small plastic tube, the switches open or close giving a dot or dash output. The World Magnetics PSF102 range of pressure, vacuum and differential pressure switches come in a variety of pressure ports, ranges and electrical configurations making this switch the ideal choice for this and other unique or challenging applications.  If you have a pressure switch emergency, the World Magnetics Company would be happy to help you develop a solution!

The World Magnetics range of switches are US manufactured and are custom built in their facility in Traverse City, Michigan.  With over 50 years of experience in the design, manufacture and supply of custom switches for Industrial, Medical, Aerospace & Military industries, World Magnetics company is the ideal choice to assist with all your Pressure, Vacuum and Differential pressure switch needs.   Our passionate customer focus and complete end-to-end manufacturing capabilities provide many customer benefits, including simplified custom engineering; quick service; and high-quality, durable product solutions.  For further information on the World Magnetics Range of switches or a free sample of what we have to offer, please visit: www.worldmagnetics.com or call the technical sales team at 231-946-3800.
