The present invention relates to an actuating method and device which allows mechanically converting rotational movement into helicoidal movement, said helicoidal movement including considerable travel in the axial direction. To that end, the device comprises a rotating rod (1) inside a fixed outer body (2). The rod (1) comprises an emerging lug (4) sliding between two parallel surfaces (3) of the outer body (2), said parallel surfaces (3) being inclined with respect to the axial axis (5) of the rod (1).

An isolating ground switch includes an enclosure with a frontal surface. A slide channel opens through the top of the enclosure. A conductive switch plate is received in the channel and is bi-directionally slidably positionable between the first position and the second position. A plurality of terminal studs project forwardly from the frontal surface of the enclosure and rearwardly conductively communicate with a conductive portion. When the switch plate is in the first position, the conductive portion engages the switch plate. When the switch plate is in the second position, the conductive portion is isolated from the switch plate.

The invention relates to a switch having a switch housing, a number of module-type individual interrupter chambers which can be arranged in particular side by side in the switch housing and having at least two switching contact elements, and an actuating device which closes off the switch housing above the individual interrupter chambers. This actuating device serves to adjust a cam element for the selective establishment of an electrical connection between the switching contact elements of an individual interrupter chamber. The switching contact elements can be arranged in at least two different orientations in each individual interrupter chamber in an explosion-protected manner. Furthermore, in particular the cam element of the actuating device can be arranged differently depending on the orientation of the switching contact elements. This results in a switch with a simple adaptation option for housing installation or front-panel mounting, wherein all requirements for explosion protection are also fulfilled at the same time.

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 actuator assembly for actuating an electrical switch housed in sealed electrical enclosure is disclosed. The actuator assembly includes a handle assembly including a handle positioned on an exterior of a cover of the sealed enclosure, a trip bracket positioned within the sealed enclosure and a shaft connecting the handle to the trip bracket. A slider actuator is slidably mounted over an electrical switch positioned within the enclosure and operatively associated with or coupled to a toggle of the electrical switch. The slider actuator has a drive link which is adapted to engage the trip bracket such that rotation of the handle activates the drive link which causes linear movement of the slider actuator to move the electrical switch between on and off positions. The use of the slider actuator allows a higher density of electrical switches to be stacked within the sealed enclosure.

A control ring (4) provides discrete changes in rotational position to indicate control by a switch assembly (1a) with perceivable haptic response indicating effected changes, wherein a slider (5) is provided with ability to come to an equilibrium position along an axis of rotation (A), wherein the control ring (4) is provided with a number of substantially equiangularly disposed radial protrusions (42a, 42b), wherein the slider (5) is provided with a radial protrusion (52a, 52b) that extends in an area of a circumference defined by the ring's radial protrusions (42a, 42b), wherein the equilibrium position of the slider remains between two adjoining radial protrusions (42a, 42b) of the ring, wherein the radial protrusion (52a) of the slider (5) has a form of a cam (8) having two angularly external surfaces (81, 82) slanted at the same orientation (α.sub.1, α.sub.2) with respect to the plane containing said axis of rotation (A).

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.

An electric switch of the normally open type includes a body made of insulating material, an actuator that is moveable between a high rest position and a low active contact position, a first elastically deformable contact blade supported by the body, and a second elastically deformable contact blade supported by the body. A first contact section of the first contact blade extends above a second contact section of the second contact blade. The first and second contact sections are superposed and are vertically distanced from each other when the actuator is in high rest position, and are in mutual electrical contact when the actuator is in low position so as to establish an electrical switching path.
