Otto Dunkel's revolutionary idea

How ODU became what it is today

There is magic in every beginning. The inventor Otto Dunkel quickly recognized the magic behind an everyday observation – and used it to develop the world’s first spring contact.

His observation

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.

The idea

Analogous to the individual brushwood branches of the broom, Otto Dunkel divided the contact surface into individual feathers, resulting in a multitude of contact points.

The result

The result was a revolutionary contact – characterized 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.
