Patent number: 11306513Abstract: A lockout prevention system for safety switches. The system may be universal, in that it may be installed on various different brands and styles of industrial safety switch gear boxes. The system blocks a locking aperture when a lever arm is in a “non-off position” (e.g. displaced away from the “off” position). This prevents users from accidentally locking a padlock in the locking aperture while the switch is in an “on position”. The system still allows a user to lock the lever arm in the “off position”. The device may be universally mounted to switch boxes using two or more bolts. Further, the system is height-adjustable.Type: GrantFiled: September 18, 2019Date of Patent: April 19, 2022Inventor: Chad Marshall
