A lock lever structure includes a shaft; a cam attached to the shaft to fit a different-shaped portion of the shaft to prevent rotation of the cam in a circumferential direction of the shaft, the different-shaped portion having a different shape in cross section from a round portion of the shaft; a lever having an inner hollow cylindrical portion larger than an outline of the shaft and attached to the shaft to be rotatable in the circumferential direction of the shaft; a spring attached to the shaft to press the cam and the lever in an axial direction of the shaft; and a retainer attached to the shaft to retain the spring, the cam, and the lever to the shaft. The cam has at least two valley portions. The lever has a contact portion to contact the cam. The contact portion has a base shape.

A water meter pit assembly includes a water meter pit frame defining an opening and a cover supported within the opening. A latch is moveable between a locked position where the cover is held fixed relative to the water meter pit frame to close the opening and an unlocked position where the cover is moveable relative to the water meter pit frame to allow access to the opening. The latch comprises a rotatable cam that engages the water meter pit frame when in the locked position.

A closing and latching mechanism for a closure in which further rotation of an input shaft in a latching direction results in engagement of a release cam with a release cam follower and movement of a release slider which moves a pawl into a position in which a claw is free to move from a latched position to an unlatched position and the claw then moves towards the unlatched position under the action of a biasing spring.

An electronic lock and system particularly for replacing existing mechanical locks for enclosures including gaming devices are disclosed herein. According to one embodiment, the gaming device includes a cabinet having a chassis and a main gaming device door locked by a mechanical lock. The electronic lock is configured to have a profile to replace the existing mechanical locks and includes a rotatable bolt receiving a sleeve. In a retained and locked position the sleeve is within the lock barrel and an operator is nested in a pocket in the barrel head. Upon receiving a command a motor rotates a cam and the sleeve is released to axially move to release the operator from the pocket for rotation of the sleeve and bolt to unlock the door. Sensors sense for fault conditions. Authentication is required to provoke the opening command. Opening events may be logged at a system server or local memory.

An operating mechanism is provided for an electrical enclosure. The operating mechanism includes a switch operator, and a housing to house the switch operator. The switch operator includes a portion which extends through one of one or more holes in the electrical enclosure, and can be manipulated by an external handle to operate an electrical switching device, such as a circuit breaker, that is housed in the electrical enclosure. The housing includes a cavity to house and protect an external antenna or other electrical device, which is connectable to an electrical cable that extends from the cavity into an interior of the electrical enclosure via the hole(s). The electrical cable can be connected to a monitoring system inside of the electrical enclosure. The housing is mountable onto an exterior surface of a wall of the electrical enclosure to cover the hole(s).
