The present disclosure relates to a button structure and a display device having the button structure. The button structure includes a housing, a function control substrate, a mechanical button and a remote control module. The housing has a reception space and a connection structure, is detachably connected to an electronic device through the connection structure, and has an installation surface to be docked to the electronic device, the installation surface is provided with a cable hole which communicates with the reception space, the electronic device is provided with a hole corresponding to the cable hole. The function control substrate is provided within the reception space and is connected with a cable, which extends into the electronic device via the cable hole and the hole and is connected to an electronic element inside the electronic device.

The present invention provides, in some aspects, a rugged and inexpensive joystick assembly comprising a core configured to manipulate a series of switches and located by an elastomeric overlay. The elastomeric overlay can include a tactile surface for a user, a water-resistant coating for a switch panel and a flex-wall disposed between the tactile surface and switch panel coating. The elastomeric overlay can be configured to positively locate the joystick core relative to the switch panel and provide a water-tight seal. The thickness, width and hardness of the flex-wall can be tuned to provide adequate locating strength and resistance to wear.

A safety switch for the control of access for machines and industrial plants comprises a casing adapted to be fastened to a fixed part of the access to be controlled and housing thereinside switching means) for controlling one or more control and/or service circuits of the machine or plant, driving means adapted to interact with the switching means upon the opening/closing of the access for opening/closing one or more circuits, anchoring means of the casing to the fixed part of the access, the anchoring means being integrated in the casing and adapted to allow the selective fixing to the fixed part of the access according to at least two mutually angled orientations, one or more auxiliary modules adapted to be selectively mounted to the longitudinal upper end of the casing, fixing means for fixing the one or more auxiliary modules to the casing.

A vacuum bottle that is intended for an electrical switching device includes a cylindrical body of insulating material closed at each end respectively by a first metal cover and a second metal cover, and a mobile electrode that passes through the first cover and that cooperates with a fixed electrode between a closed position in which the two electrodes are in contact with each other and an open position in which the two electrodes are separated. The bottle includes the second cover corresponding to the fixed electrode of the vacuum bottle.

According to an embodiment, a switch attachment member includes a support that is formed to be attachable between a steering wheel and a steering boss, and supports a switch. The support is formed to be capable of changing a position of the switch.

A coupled structure capable of keeping the coupled state between coupled members without degrading the appearance, and an electronic device including such a coupled structure are disclosed. A coupled structure includes a keyboard unit coupled with a main body chassis. The coupled structure includes a hook mechanism which engages the keyboard unit with the main body chassis when the keyboard unit moves in one direction relative to the main body chassis, a locking part formed at the main body chassis, and an elastic part formed at the keyboard unit, and the elastic part biases the keyboard unit engaged with main body chassis in the one direction relative to the main body chassis when the locking part locks the elastic part.
