Why Was the MAGNASPHERE Switch Invented?


“Most people don’t realize how easy it is for an intruder to defeat a reed switch security system contact and evade detection,” said Rick Kirschman, Founder of MAGNASPHERE Corp. “Magnets are the kryptonite to the common reed switch. If a rogue magnet was placed within range of a reed switch contact, an intruder could enter almost any home undetected without triggering an alarm. How safe are you really if your home security system can be defeated with a simple magnet?”

Invented by Dr. Randall Woods, the MAGNASPHERE high security switch was designed to address the undetected breaches of security that could occur while using reed switch based home security system contacts.“When my neighbor’s home got robbed and the alarm didn’t go off, I wanted to know why,” said Dr. Woods. “I soon discovered the reed switch security flaw and set out to design a more secure switch technology that would do the job that I thought the reed switch contact was supposed to do.”

In the 1970’s, once it was discovered how easy it was to defeat a reed switch contact, the US Government demanded a more effective countermeasure to protect its highest classified areas. While these magnetic defeat resistant devices are now commonly used to detect breaches in high security facilities, their high cost and large size made them an impractical security solution for most residential applications. Resistant to external magnetic defeat tampering and virtually unbreakable, MAGNASPHERE’s patented “reed switch free” technology provides the absolute highest level of intrusion detection available to any security system owner today. In fact, MAGNASPHERE provides the same level of external magnetic defeat protection found in the Federal Government’s most secure installations, but at a fraction of the cost and size.

The founders of MAGNASPHERE Corp. realized that many of the same features that provide the security benefits of the MAGNASPHERE switch, were also important benefits for switches used in non-security applications – the robust construction, directional sense zone, and another feature, the ability to sense a ferrous metal target. This ferrous proximity sensing feature truly sets the MAGNASPHERE technology apart from other magnetic switching technologies and has opened the door for endless potential applications in the industrial and commercial product marketplace such as:

  • Automotive
  • Medical
  • Aerospace
  • Gas and Oil
  • Agricultural
  • Military
