Abstract: A vacuum valve includes a structure having: a container in which a fixed-side end plate and a movable-side end plate are fixed to both ends of an insulation cylinder; and an arc shield at an intermediate portion of the insulation cylinder. The vacuum valve includes: a voltage nonlinear resistance layer containing particles having a voltage nonlinear resistance characteristic at at least either one of an outer creepage surface or an inner creepage surface of the insulation cylinder. A filling rate of the particles in the voltage nonlinear resistance layer has a distribution along a film thickness direction, and a filling rate of the particles in an outermost layer is not greater than half of an average filling rate of the particles in an entirety of the voltage nonlinear resistance layer.

Abstract: A panel structure includes: a sheet-shaped core member having a thermoplastic property and provided with a plurality of protruding portions in at least one surface; a sheet-shaped faceplate having a thermoplastic property and disposed on the plurality of protruding portions; and a fusing portion which is selectively formed between the faceplate and the plurality of protruding portions and which bonds the core member and the faceplate to each other.

Abstract: A switch device has a case, an operation knob disposed above the case, and a connector disposed under the case. The connector has connection terminals and a housing supporting the connection terminals, the housing being formed with an opening portion from which the connection terminals are led out. The case is provided with an impervious wall extending downward from the case so as to be opposed to both side surfaces of the housing parallel to a leading-out direction of the connection terminals. The impervious wall is arranged across a gap from each of the both side surfaces of the housing.

Abstract: There is provided a switch device including a tubular portion which is provided in a casing and is opened at its upper and lower surfaces; a supporting shaft provided in the tubular portion; a manipulation knob which is mounted to the tubular portion such that it covers the opening in the upper surface and is operated to be rotated about the supporting shaft by being manipulated; a switch provided in the casing; a manipulation bar for transmitting the rotating operation on the manipulation knob for changing over the switch between an ON state and an OFF state; an elastic member which generates an elastic force for restoring, to a predetermined rest position, the manipulation knob which has been operated to be rotated; and a first impingement portion and a first to-be-impinged portion which are provided in the manipulation knob and in the tubular portion and are impinged on each other if the manipulation knob is operated to be rotated to reach a limit of this operation, wherein a second impingement portion and

Abstract: A switching device capable of preventing entrance of water from outside of a case through a space below an operation knob into the case is disclosed. The switching device includes: a switch; a case within which the switch is accommodated; a hollow cylinder which is formed integrally with the upper surface of the case and open to above and below to communicate with the inside of the case; an operation knob provided to cover an upper opening of the cylinder such that the operation knob can swing; and an operation bar which extends through a lower opening of the cylinder into the case to transmit the motion of the operation knob to the switch. A concave is formed on the upper surface of the case at a position around the cylinder. A lid for covering a part of the concave is provided on the concave near the cylinder.

Abstract: A switching apparatus includes a case, an operation shaft whose one end outwardly projects from inside of the case and which is provided at its central portion with a flange, a support member which supports the flange such that the operation shaft can rock and rotate, an operation knob mounted on one end of the operation shaft, a first contact which is switched when the operation knob is pushed to move the operation shaft, a second contact which is switched when the operation knob is rotated to rotate the operation shaft, and a third contact which is switched when the operation knob is rocked to rock the operation shaft.
