A combination faux switch and sliding bolt lock, one or more imitation switches mounted on a cover to an enclosure, the cover and switches resembling a circuit breaker panel, each switch having a toggle arm including a back portion disposed in the enclosure behind the cover, manipulation of the toggle arm moving the back portion between first and second positions, the back portion slidably attached to a bolt one end of which is received in an aperture in the side walls of the enclosure locking the cover to the enclosure. One embodiment of the invention includes a plurality of combination faux switched and sliding bolts such that a locking combination may consist of any combination of the switches appearing to be in “off” or “on” positions.

A mechanical lock box comprising a housing including a lid and a hook fastener attached to the lid and a 3D multi-level printed maze. A release chamber is located within the maze and a ball is enclosed in the maze. The mechanical lock box further includes a hook bar having a first hook bar end which pivotally connects to a pivot box in the maze and a second hook bar end having a lock hook configured to engage with the hook fastener to hold the lid in a locked position. A hook pusher is configured to pivot the hook bar to unlock the lid when the ball pushes against the hook pusher.

The present invention relates to electronic and mechanical dual combination locks. In certain embodiments, electronic and mechanical dual combination locks include: a lock base, a spin dial, a spin dial cover, and a spin dial release conversion mechanism. The lock base includes a mechanical combination lock inside. An electronic combination lock is positioned inside the spin dial cover. The spin dial release conversion mechanism has a spin dial release positioned on the top of the lock base. The spin dial release is used by the user to switch the electronic and mechanical dual combination lock between the electronic combination lock and the mechanical combination lock. When spin dial release is placed in a first position, the electronic and mechanical dual combination lock becomes the electronic combination lock. When the spin dial release is placed in a second position, the electronic and mechanical dual combination lock becomes the mechanical combination lock.
