A vertical interlock system, comprising: a power supply generating a bypass signal; a first breaker connected to the power supply and controlled by a first switch; a second breaker connected to the power supply and controlled by a second switch, the second breaker being located above the first breaker; a control lever having a first orientation and a second orientation; and a fixer for locking the control lever in either the first or second orientation, wherein when the control lever is in the first orientation the first switch is locked closed, when the control lever is in the second orientation the second switch is locked closed position, when the first switch is open, the control lever cannot be placed in the first orientation, and when the second switch is open, the control lever cannot be placed in the second orientation.

Vertical interlock system

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.
