Assembly of disconnect terminals having a coupling device, and switching status display
An assembly includes at least two disconnect terminals and at least one coupling device, wherein the at least two disconnect terminals each include at least one switching lever. Each switching lever is adjustable independently from the other switching lever from a first switch position into at least one second switch position and back, wherein the switching levers are connectable by the at least one coupling device. The at least one coupling device connects the switching levers if the at least one coupling device is switched into at least one first coupling position, and the at least one coupling device separates the switching levers from one another if the at least one coupling device is switched into at least one second coupling position. A disconnect terminal includes the at least one coupling device.
Wall grazer apparatus
A wall grazer apparatus is provided. The wall grazer apparatus has a heat sink platform, a light source, a lens, a driver and a main housing. The heat sink platform has a main portion and a tilt portion. The light source is mounted on the tilt portion. The lens is disposed above the light source to convert an original light emitted from the light source to an output light. The driver converts an external power to a driving current. The driving current is supplied to the light source. The main housing disposes the heat sink platform, the light source, the lens and the driver. When the main housing is fixed to a first surface, the output light is projected on a second surface for forming a visual effect.
Rotary handle construction of an electrical switch
The construction comprises a rotary handle with a first pivot axis, a locking latch with a second pivot axis, a fixed bottom ring, a locking pin movable with the locking latch between a first position in which the rotary handle can be turned in relation to the bottom ring and a second position in which the locking pin prevents turning of the rotary handle in relation to the bottom ring, a shaft adapter rotationally movable against a spring force in relation to the rotary handle. The shaft adapter comprises a protrusion having a locking member which locks the locking pin into the first position when the torsional moment acting on the rotary handle exceeds the spring force acting on the shaft adapter causing a limited rotational movement of the shaft adapter in relation to the rotary handle.
Switch unit
A switch unit includes a switch body and a switch base. The switch body is subjected to a pull-up operation from a normal position to an operated position. The switch base supports the switch body such that the switch body is pivotable about an axis parallel to a first direction extending. The switch body includes an aesthetic wall disposed to extend along an opening, and an operation wall extending toward an inner side relative to the aesthetic surface from one side at an outer edge of the aesthetic wall, the one side extending in the first direction. The operation wall is located inward of an arc centered on the axis, the arc passing through the one side extending in the first direction. A shielding wall intersecting the first direction is provided at at least one of both side edges of the operation wall in the first direction.
Operation device and operation member
An operation device includes a housing, an operation member, and a detector. The housing includes an electrically conductive portion on a surface thereof. The operation member is supported by the housing such that the operation member is movable in response to an operation by an operation body, and is configured to be capacitively coupled to the operation body and to the electrically conductive portion. The detector is configured to detect whether the operation body is in proximity to the operation member based on a change in capacitance at the electrically conductive portion.
