Abstract: A storage structure includes a cover, a main body, and a movable element. The main body includes a first board and a cavity. The first board has a first opening. The cover connects to the main body. The movable element is accommodated in the cavity and selectively disposed in the first opening.

Abstract: An actuator system for operating a switch is described herein. The actuator system can include a shaft of a handle assembly. The shaft couples to a handle and a male coupling element and has a number of positions. Further, a coupling body of a switch assembly can be positioned in the number of positions. The coupling body engages the switch and has a female coupling element, which has a slotted portion that receives the male coupling element and an angled terminus that aligns the shaft to a first position as the shaft couples to the coupling body. The slotted portion receives and engages the male coupling element when the shaft is coupled to the coupling body. The slotted portion prevents the male coupling element from disengaging when the coupling body is in a second position, and disengages the male coupling element when the coupling body is in the first position.

Abstract: A system and method according to which one or more sliders are actuated in order to, for example, operate one or more switches such as, for example, one or more circuit breaker switches.

Abstract: A battery-powered apparatus for holding and energizing an electric transducer, includes a hand-held battery housing carrying the transducer mount, and first and second internal battery contacts. A first external battery charge terminal is on the transducer mount, and a second external battery charge terminal is on a part of the battery housing, such as its end cap. A double-throw switch has a common element electrically connected to an internal battery terminal contact, has a first switched contact leading to a first terminal of the electric transducer, and has opposite second switched contact electrically connected to an external battery charge terminal. If there are two electric transducers, they may be a part of a light source comprising a reflector, a first electric lamp having a filament at its focal point, and a second electric lamp extending into that reflector beside the first electric lamp.
