As the saying goes, every beginning holds a special kind of magic. The inventor Otto Dunkel quickly recognized the magic behind an everyday observation – and used it to develop the world’s first spring contact.
Otto Dunkel experienced one of his most profound flashes of inspiration when he observed a man sweeping leaves with a twig broom. This moment was nothing less than the birth of the springwire contact.
Analogous to the individual brushwood branches of the broom, Otto Dunkel divided his new contact into lines, i.e., small, individual springs. Like the twigs in the broom, these also expand on contact.
The result was a revolutionary contact – characterised by consistent contact resistance and pressure. Thanks to the new connector, a major shortcoming of the message transmission equipment in use at the time, namely the unreliable plug-in contacts, had finally been overcome.
Otto Dunkel GmbH receives the patent for producing the „spring‐loaded plug pin“ – inspired by a twig broom – known today as „ODU SPRINGTAC®“.
