Our Story

IDEM Safety Switches

IDEM Safety Switches was created in 2003 by Medi Motasham, the former Head of Research and Development at EJA/Guardmaster. Over 18 years as Technical Director of EJA/Guardmaster, and later Rockwell Automation, he designed and developed the popular Guardmaster Brand Products that included Trojan, Titan, Cadet, Rotacam, Ferrogard, Spartan, Lifeline, Minotaur, etc. Now leading IDEM's team, currently with over 200 years' experience between them. He has set a new industry standard by offering the "Next Generation" of Machine Safety Interlocks and Devices. With higher reliability, increased features, and up to date durability to cope with the ever-increasing environmental demands placed on Machine Safety Devices..

Beginning in 1985, Medi got to work and in 1986 designed the Trojan, Atlas, Rotacam, and the LRS1 Rope Switches. From 1990-1996, Ferrogard and the LRS4 were added while Guardmaster gained popularity and in 1999, was acquired by Rockwell Automation. In 2003, Medi left Rockwell to create IDEM Safety Switches. With a vision to develop the “Next Generation” of Safety Switches while manufacturing in the United Kingdom. In 2006-2010, IDEM designed the Guardian Rope Pull, Kobra Tongue Switches, Idemag, and Idecode Non-Contacts switches. By 2011 IDEM purchased our purpose built factory back where it all started, the old Rockwell building. IDEM has since rehired a lot of the ex-Guardmaster/Rockwell employees as 80% of our personnel come from Medi’s time there. IDEM is constantly designing new products and improving current products by fostering innovation, ingenuity, and maintaining compliance with the latest Safety Standards.

The Odo J. Struger Automation Award is an honor bestowed annually on the engineer who has made the most outstanding contribution in the field of automation. The winner of the award for 2000 is Medi Motasham, Director of Research and Development at Guardmaster, UK in the Components and Packaging Group.

Medi, an employee of Rockwell Automation with the acquisition of EJA Ltd. in 1999, was honored for his contributions to the development of machine safety components.

Having been responsible for the initial set up of the Research and Development department of EJA, Medi initiated the design and invention of the majority of EJA's Safety Switches and was also responsible for the launch of Trojan, Titan, Atlas, LRS Rope Switches and various other Safety Products which are distributed on a worldwide basis.

His distinguished contribution to the Guardmaster line of safety products culminated in his increased responsibility for the design of Guardmaster, Sigma and Nelsa product lines.
