Apparatus and associated methods relate to an access control system having a planar interlocking mechanism including two reflectively symmetric rotating moon gears mechanically coupled by a linear slide configured to respond to rotation of the moon gears. In an illustrative example, the moon gears are mechanically coupled by the linear slide via respective actuating cams. The moon gears may be provided, for example, with locking cams configured to releasably secure the linear slide via a corresponding follower on the linear slide. Rotation of one moon gear into a first mode may, for example, place the other moon gear in a second mode, and vice versa. Each moon gear may be configured, for example, to be operated by a removable peg. Various embodiments may advantageously be configured such that release of a removable peg from one moon gear captures a peg in a corresponding moon gear.

A cable operated mechanical locking external disconnect enclosure for multi-point latch uses. The enclosures provide safety, in that, once the main enclosure door is closed, and the disconnect is turned on, the main enclosure is locked and only automatically unlocks when the disconnect is turned off. Thus, the door of the disconnect enclosure is locked when the disconnect or circuit breakers are turned to the on position. There is also a manual by-pass latch for each door.

A rotary drive actuation system for actuating a latch including: an output shaft having a member affixed at one end of the output shaft for coupling to a component of the latch; a common drive element affixed to the output shaft at the other end of the output shaft; and a plurality of motors coupled to the common drive element for simultaneously driving the common drive element and the output shaft in a first rotary direction to effect actuation of the latch.
