A hand grip for use in controlling machinery. The grip includes a grip body and a hand rest connected to the grip body. The hand rest adjustably slides and rotates with respect the grip body grip. The hand rest includes a first locking part that is configured to engage the grip body to lock the hand rest in a locked position with respect to the grip body such that the hand rest does not slide with respect to the grip body and configured to disengage from the grip body such that the hand rest slidably moves with respect to the grip body. The hand rest includes a second locking part that, when unlocked, allows the hand rest to rotate with respect to the grip body, and that, when locked, prevents the hand rest from rotating with respect to the grip body.

Adjustable grip hand rest

A fuse for a high voltage/high current application, such as a hydro-electric vehicle ('HEV') application is provided. The fuse employs a variety of arc quenching features to handle a large amount of arcing energy that is generated when such fuse is opened due to a fuse opening event. In one embodiment, an insulative substrate, such as a melamine substrate, is metallized with a fuse element. The fuse element extends to multiple surfaces of the substrate. A fuse opening portion of the element is located so that the arcing energy is forced to travel along multiple insulative planes, increasing an impedance across the opening of the element and decreasing the likelihood of a sustained arc. Also, the substrate and element are disposed in a sealed housing, which is packed in one embodiment with an arc quenching material, such as sand.
