Publication number: 20210219407Abstract: An electrostatic dissipation device having a housing constructed with a protruding conductive element that fixes to a grounded feature of the environment, such as the ground return of a household electrical system. A second moveable conductive element is partially contained within the housing and can be mechanically moved to electrically connect with the first element. The second element is also connected to a spring that widens the contact area between the second element and the human operator by requiring some depressive force. Dissipation of static charge from the human operator occurs as the second conductive element becomes close enough to the arcing distance to the first conductive element. Pain is minimized for the human operator while dissipating static charge.Type: ApplicationFiled: January 13, 2020Publication date: July 15, 2021Inventor: Ronald Matthew PAYNE
