Abstract
A electrically operated blocking device used to block the operation of electrical or mechanical equipment without using a system of deadbolt locks, keys, and electrically operated key traps. The electrically operated blocking device preferably includes a blocking shaft used to block the operation of electrical equipment such as, e.g., switches, circuit breakers and other similar electrical equipment, or mechanical equipment such as, e.g., valves, cams, gears, doors or any moving device or device operator, and preferably includes a keyless solenoid release unit (KSRU) used to control a plunger that locks the blocking shaft into place and unlocks the blocking shaft to allow the blocking shaft to move freely along its axis.
