Abstract: A switch lever lock out assembly engagable with a switch. The assembly includes a lock out body engageable with a switch to prevent operation of the switch. A lever engaging member is mounted to the body, and has a lock position and an unlock position. In the lock position, the lever engaging member prevents disengaging the body from the switch. A blocking member is movably fixed to the body, and is engageable with the lever engaging member to prevent movement of the lever engaging member relative to the body when the lever engaging member is in the lock position. The blocking member is locked relative to the body by a key engageable mechanism. In another aspect of the invention, the key is fixed to a tether forming part of the assembly, and the key is lockable in a lock rail fixed within an area defined by the tether.

Abstract: A locking attachment is for a circuit breaker. The circuit breaker includes a housing enclosing separable contacts and an operating mechanism, an elongated operating member with a handle that operates to open and close the separable contacts, and an opening in the housing through which the elongated operating member protrudes. The opening has first and second ends corresponding to “on” and “off” circuit breaker positions, respectively. The locking attachment includes a locking member having a first end having a compressive segment with opposed portions for compressively capturing the operating member. The second end of the locking member is structured to engage the housing of the circuit breaker at one of the first and second ends of the opening in the housing, thereby locking the circuit breaker in either the “on” or “off” position.

The switch-lock attachment includes a spring member adapted to engage a retaining area of the circuit breaker, a support member adapted to accommodate the spring member, and a locking member connected with the support member via the spring member. The insert includes a securing end adapted to engage a first area of the circuit breaker for limiting the movement of the insert relative to the circuit breaker, and an interface area adapted to engage the switch-lock attachment for limiting the movement of the switch-lock attachment relative to the insert.

Abstract: A device is provided for preventing accidental operation of a switch including a body having a surface with an opening and a cavity extending from the opening at an angle for receiving and releasably engaging the actuator member of a switch. With the switch in the desired on or off position, its actuator member is mounted into the cavity to engage the device, via the opening, such that the surface of the body lies adjacent the switch plate. Operation of the switch is prevented by the surface of the body providing a stop against the switch plate without physically anchoring the device to the switch plate.

Abstract: A circuit breaker safety clip and associated method are provided to identify and secure circuit breakers in an open position. The safety clip securely engages a circuit breaker in an electrical panel such that the circuit breaker must remain in an open position while the safety clip is attached thereto. The size and shape of the safety clip are selected such that the safety clip does not contact, and thus does not damage, other portions of the electrical panel. The safety clip design also provides ease of installation and removal. Additionally, the safety clip may include a warning tag that is durably attached and is appropriately sized to be noticeable without blocking the view of other circuit breakers. Still further, the wrap-around safety clip design of one embodiment protects at least part of the circuit breaker, typically the head of the circuit breaker, from direct impact.

Abstract: A hookstick operated switch assembly includes a switch mounted to a support and movable between open and closed positions. An operating lever is connected to the switch for opening and closing the switch. A locking arm is positioned proximal the switch. A locking member is receivable by the locking arm when the switch is in the open position to prevent movement of the operating lever, thereby locking the switch in the open position.

Abstract: A locking device for use on an electric disconnect switch having a handle operator assembly. The locking device includes a slide plate slidably positioned within the housing and a first lock arranged to engage said slide plate and secure the handle operator assembly in an engaged position.

Abstract: An interlock device using locks to prevent manual actuation of a switch having a handle inlet, and to allow the switch to be actuated manually in a certain sequence of operations determined by using keys for the locks, thereby enabling the switch to pass from a first switching position to a second switching position, the device comprising a first lock and a second lock each operable by means of at least one key capable of being withdrawn from the corresponding lock or of being engaged in said lock only when the lock is in its locked position, a set of cams whose rotation is tied to actuation of the switch and which act on the bolts of said locks to prevent the first lock from being operated so long as the second switch is not in its second switching position and to prevent the second lock being operated by its key as soon as the second switch no longer occupies its first switching position, both locks being disposed in such a manner that their respective bolts, when in the advanced position, close the handle

Abstract: A portable electric appliance including a housing defining an air inlet, an air outlet and an air flow path therebetween; a conditioner disposed in the air flow path and operable to condition air in the air flow path; a power source; and an electrical switch connected between the conditioner and the power source and having an actuator movable between an inactive position and at least one active position, the switch in its one active position transmitting power from the source to the conditioner, and in its inactive position preventing power transmission therebetween. Also included is a lock mechanism including a release element adapted for predetermined movement between a locked position and an unlocked position, the actuator and release element being shaped and arranged to require independent manipulation by, respectively, first and second body parts; and in its locked position the element prevents the given movement of the actuator, and in its unlocked position allows the given movement of the actuator.

Abstract: A configuration switch assembly for a computer system includes a protected switch for selectively enabling or disabling a function of the computer system, as determined by the state of the switch. The switch is mounted on the interior surface of a chassis panel. In one embodiment, a slide lock is installed in a guide on the exterior surface of the chassis panel. The slide lock alternatively engages, or disengages from, the switch as it travels between two limit positions that are determined by an aperture in the guide and a cam extending from the slide lock. The slide lock is lockable in one of the two positions so that when the slide lock is locked, the state of the protected switch cannot be altered, and the function, as established by the locked state of the switch, is protected.

Abstract: An illumination device includes a housing and a multi-position switch for selecting various modes of operation. A security block is mounted to the housing adjacent the switch. The security block may be attached to the housing in at least two different orientations. In a first orientation, the security block prevents the switch from being in a position corresponding to certain modes (e.g., those which create a high intensity light beam). When positioned in a second orientation, the security block is attached to the housing but permits the switch to be in other or all positions, thereby permitting various modes of operation.
