A clicking mechanism toy having a body and head in the form of an animal or insect. The body accommodates a multitude of clicking mechanisms. Optionally a depressible push button of the clicking mechanism is colored, is transparent and can be illuminated. Also optionally such a version can be used in a pattern game where a push button illuminates until it is depressed and in another game where a user determines how fast the user can press an illuminated push button, causing the illumination to cease. The light can be within a housing for the push button or within the body of the toy. In one such version the single light directly illuminates all the push buttons, and in another such version fiber optic fibers go from a light source to each push button, enabling individual control and the aforementioned games.

The invention provides a rotary or touch-sensitive control comprising a first rotatable and/or touch-sensitive body comprising means for displaying information relating to a parameter controlled by the first body, and a second rotatable and/or touch-sensitive body formed around the first rotatable body comprising means for displaying information relating to a parameter controlled by the second rotatable body.

An operator control apparatus for a domestic appliance includes a carrier plate and an operator control element which is rotatably arranged on the carrier plate for setting an operating condition of the domestic appliance. The operator control element includes a front cap having a first transparent region and a second transparent region which is separate from the first transparent region. A light guide extends into the front cap to guide light from a light source such as to illuminate the first transparent region with a first light intensity of the light which is coupled out of the light guide, and to illuminate the second transparent region with a second light intensity of the light which is coupled out of the light guide, with the second light intensity of the light being different from the first light intensity.

Systems and methods are disclosed that may be implemented to provide keycap lighting to a spring loaded mechanical key switch assembly using a light conductive structure, such as a light pipe, and without requiring a chassis housing of the mechanical key switch assembly to include a dedicated power-consuming light source mounted to or otherwise positioned at the location of the individual key switch assembly chassis housing. Additionally, the disclosed systems and methods may be implemented to use one or more common power-consuming light source/s to simultaneously provide key cap lighting to multiple such spring loaded mechanical key switch assemblies, for example, by feeding light to each key cap though a common light spreader and through an individual non-power consuming light pipe provided for each key switch assembly.

Disconnect operating handles for circuit breakers are configured with a rotary handle attached to an inwardly oriented shaft that connects to a gear assembly that translates rotational input to linear input. The disconnect operating handles include pivoting lockout levers that can automatically pop out to expose the lockout space for a padlock when a user touches the lever in an appropriate location.

A latch system for an electrical equipment enclosure includes a chassis and a latch arm, engaged with a circuit breaker, that moves between first, second, and intermediate arm positions. A handle operatively connected to the circuit breaker is movable between ON, TRIP, OFF, and RESET handle positions. The handle is operatively connected to the latch arm such that the latch arm is positioned in the second arm position when the handle is located in said RESET handle position. The latch arm spring biases the latch arm into the first or intermediate positions when the handle is in the ON, TRIP, or OFF handle position. A lockout plunger is connected to the handle to rotate with the handle and is movable between disengaged and engaged positions. The lockout plunger prevents movement of the handle from the OFF to the ON handle position when the lockout plunger is in its engaged position.

A non-contact button assembly for a powered surgical instrument includes a light emitter, a rocker switch, and a button shaft. The rocker switch defines a through passage about a longitudinal axis of the button assembly. The button shaft is disposed within the through passage. The button shaft includes a proximal portion, a distal portion, and a flange positioned therebetween. The button shaft has a deactivated position such that the button shaft is configured to prevent light from the light emitter from illuminating a light detector and the button shaft has an activated position such that the button shaft is configured to permit light emitted from the light emitter to illuminate the light detector.

Disconnect operating handles for circuit breakers are configured with a rotary handle attached to an inwardly oriented shaft that connects to a gear assembly that translates rotational input to linear input. The disconnect operating handles include pivoting lockout levers that can automatically pop out to expose the lockout space for a padlock when a user touches the lever in an appropriate location.

A backlight module including a circuit layer, a light guide plate, a light-emitting component, an electronic component, a reflective layer, and an identifier is provided. The light guide plate includes an escape opening and a light-source opening. The light-emitting component is connected to the circuit layer. The electronic component is connected to the circuit layer. The reflective layer is disposed between the light guide plate and the circuit layer. The identifier is disposed on the reflective layer. A keyboard using this backlight module is also provided.
