An external switch actuator includes: a guide tube having a first end and a second end, the first end configured to be attached to a door of a compartment in substantial alignment with both a hole in the door and a switch actuator within the compartment, and the second end configured to be disposed within an interior of the compartment and separated from the switch actuator by a gap when the door is closed; a coupling shaft configured to be operably placed within the guide tube, the coupling shaft having an electrical insulator disposed between an actuator side adapter and a switch side adapter, and a length equal to or greater than a distance between the switch actuator and the hole in the door when the door is closed.

An electronic component includes: a first substrate having a first surface; a second substrate having a second surface facing the first surface across an air gap; a first coil pattern that is located on the first surface so as to face the second surface across the air gap; a second coil pattern that is located in a second region on the second surface and faces the first surface across the air gap, at least a part of the second region overlapping with a first region in plan view, the first region being formed of a region in which the first coil pattern is located and a region surrounded by the first coil pattern; and a connection terminal connecting the first coil pattern and the second coil pattern.

An electrical appliance for connecting to a high voltage includes an active part, which is provided with a magnetizable core and at least one winding assembly, surrounding a respective core section of the core and having windings that are inductively coupled to one another. A tank, which can be filled with an insulating fluid, encases the active part. The tank has two end casings and a central part arranged between the end casings. The electrical appliance is compact and has a low tare weight. The active part is mechanically connected to the boiler only at the end casings and the end casings are supported on fasteners. The central part is produced from a light material.

The active part is entirely arranged a tank, which can be filled with an insulating fluid. The tank has two end casings and a central part arranged between the end casings. The electrical appliance is compact and has a low tare weight. The central part forms a hollow body for each winding assembly, through which a respective one of the core sections extends, which is surrounded by an associated winding assembly. The hollow bodies are connected to one another on the inside and only via the internal volume of the end casings.

An electronic component, such as, for example, a transformer, includes a core, a first wire, and a second wire. The first wire is wound at least in part about at least a portion of the core in a first winding. The second wire is wound at least in part about at least a portion of the core in a second winding such that the first winding and the second winding alternate at least in part along at least a portion of the core. The electronic component includes windings that are intertwined about the core to form an intertwined spiral winding. Such a configuration can both improve electrical characteristics of the electronic component while reducing a height of the electronic component. Further, methods of manufacturing such components and customizing same are disclosed.

Disclosed herein is a common mode filter that includes a winding core part and first and second wires wound in a same direction around the winding core part. The first and second wires constitute a first winding block on one endmost side in an axial direction of the winding core part, a second winding block on other endmost side in the axial direction of the winding core part, and a third winding block positioned between the first and second winding blocks. The second winding block is a winding block at an odd-numbered position counted from the first winding block. The first and second wires cross each other in an area between the first and third winding blocks and in an area between the second and third winding blocks.
