A switch assembly according to an example of this disclosure includes a disk rotatable about a disk axis in a first circumferential direction and a second circumferential direction opposite the first circumferential direction. A U-shaped spring is fixed to the disk. Rotation of the disk in the first circumferential direction moves the disk in a first axial direction, and rotation of the disk in the second circumferential direction moves the disk in the first axial direction.

A disconnecting switchgear has three mutually exclusive positions II-0-I, with position II energizing the load circuit, position 0 de-energizing the load circuit and position I grounding the circuit, which reduces the electrical risk when interacting with an electrical panel. The switchgear includes a control interconnected with a body, where the control includes a gripping mechanism with an electrical labelling element, an extension mechanism, a locking mechanism and indicator labels; the body includes a group of external electrical conductors or connection terminals, a group of internal electrical conductors or poles, an earth short-circuit electrical conductor, displays of electrical quantities, luminous indicators, and sight glasses for viewing moving poles; electrical conductors and electrical contacts interconnected with a drive shaft and the latter to a power-transmission mechanism.

An input device includes: a rotating member that rotates about a predetermined rotation axis; and a mover that includes a protrusion protruding toward an inner peripheral surface of the rotating member and moves in a direction different from a rotation direction of the rotating member along with rotation of the rotating member. The protrusion protrudes toward an inner peripheral surface of the rotating member. The rotating member includes a first projection and a second projection that project from the inner peripheral surface toward the mover. The protrusion of the mover is inclined with respect to the predetermined rotation axis and disposed between the first projection and the second projection.

The present invention relates to a multi-pole fused switch arrangement for busbar systems, with at least two fused switch units, each of which can accommodate a fuse. The fused switch arrangement includes a fuse holder per fused switch unit, a fuse driver unit and a switching lever, wherein the fused switch unit is designed such that it enables the insertion and replacement of fuses in a particularly advantageous manner, and furthermore brings the fuses into their contact position in a particularly advantageous manner.

A longitudinal switch for an electric contact locking and position changing system was designed to position securely the movable switch elements (7), which are urged by springs (5) and a rack (1) and toothed gear (8) mechanism for moving a vertical shaft (9), acting upon fixed elements (contacts) (16) of an electrically insulating rail surface (15). Positions are changed by turning a control button (39) and the toothed gear (8), causing the vertical shaft (9) to rotate, thus moving the rack (1) and causing the movable elements (7) to slide on the semicircular surface (17) of the fixed elements (16), overcoming the force of the springs (5) and compressing them. Once the gap between the fixed elements (16) is located, the springs (5) push back, keeping the movable elements (7) locked and ensuring the effective electric contact with the electric current passing through these points of contact.

A rotational operation type switch includes a frame; a rotational operation button rotatably supported on the frame for rotational operation; a switching contact mechanism disposed below the operation button to face the operation button; and an operation mechanism disposed between the operation button and the switching contact mechanism, to switch the switching contact mechanism in conjunction with the rotational operation of the operation button. The switching contact mechanism includes a printed circuit board, a plurality of fixed contact electrodes disposed on the printed circuit board and spaced a predetermined distance away from each other, and a movable contact having a disc spring shape and disposed bridging between the plurality of fixed contact electrodes. The movable contact deforms to contact and separate from the fixed contact electrodes and switches an electrical connection between the fixed contact electrodes.

A switch device includes a substrate including stationary contacts arranged side by side, a contact including linear parts having elasticity and movable contacts, a housing holding a base of the contact and including beams having elasticity each of which is disposed above the corresponding one of the linear parts, and a slider disposed above the housing. A first pressing part is formed on a lower face of each of the beams, and a pressed part is formed on an upper face thereof. Second pressing parts are formed on the slider. When the slider moves in the front-back direction in conjunction with the operation of an operation knob, the second pressing parts press the pressed parts to bend the beams downward, the first pressing parts press the linear parts to bend the linear parts downward, and the movable contacts come into contact with the stationary contacts.
