Handle assemblies for circuit breakers are disclosed. One illustrative handle assembly includes a housing defining a first aperture, a seal extending around a perimeter of the first aperture, a handle extending outwardly through the first aperture and pivotable about a pivot axis located within the housing, a shroud coupled to the handle to move therewith and located at least partially within the housing, and a biasing member connected to the handle and to the shroud. The shroud includes an outer surface that faces the seal, and the biasing member biases the outer surface into continuous engagement with the seal throughout an entire pivotable range of the handle.

An operation device includes a grip to be grasped by an operator, and a supporting portion supporting the grip and allowing the grip to be turned in an arbitrary turning direction. A rotation fulcrum of the grip is positioned inside the grip. In this manner, the present invention requires less hand operation and is configured to be stably operated even when a machine body is shaken.

A driving joystick arrangement for a construction machine comprises an operating lever and a basic housing, wherein the operating lever is pivoted in the basic housing, and the basic housing comprises a shift gate through which the operating lever extends. The operating lever comprises, at least in sections, a material which is suited and arranged in the operating lever such that a position of the operating lever relative to the basic housing can be detected by means of the Hall sensor.

A joystick for controlling a machine comprising; a handle assembly allowed to rotate around a central axis extending along a longitudinal direction of the joystick, a control portion having a casing in which a lower circuit with a lower sensor is provided and a control lever attached to the said casing so as to move pivotally about at a pivot axis which extends perpendicularly to the longitudinal axis of the control lever. Advantageously, said control lever having at least one embedded lower magnet is manufactured from plastic by the injection molding; said control lever comprises: at least one pivotal protrusion extending outwardly from the control lever for bearing in a housing of a casing; said pivotal protrusion forming a monolithic structure with the control lever by said injection molding and in that said lower magnet is embedded within the pivotal protrusion to be in the proximity of said lower circuit.

An accelerator device having an organ structure includes a pad, a case, an inside movable mechanism, an arm, and a cover. The pad is pressed by a driver. The case is attachable to a vehicle body and includes a front wall, a rear wall, and an opened side. The inside movable mechanism is housed in the case and includes a shaft, a pedal, and a bias member. The arm penetrates an opening of the case so as to connect the pad to the pedal. The cover covers the opened side. The case on the vehicle body includes a drain passage positioned below a lowest position of a root of the pedal in a movement track while the pedal is moved from an accelerator idle state to an accelerator full-throttle state.
