A switching assembly intended to be joined onto a control assembly provided with an actuation member, the switching assembly comprising a body, an electrical circuit comprising two fixed contacts, the electrical circuit being able to be controlled both by a control switch of a normally-closed type and by a monitoring switch of a normally-open type, linked in series with the control switch. The monitoring switch makes it possible to monitor the correct secure attachment of the switching assembly onto the control assembly by keeping the electrical circuit open as long as the control assembly is mechanically disconnected from the switching assembly.

A key mechanism comprises an elastic structure comprising a first cavity located above a second cavity which are spaced apart from each other. The key mechanism comprises first and second button structures. The second button structure comprises an electrode layer on an upper wall of the second cavity and an electrode layer on a lower wall of the second cavity. The second button structure has an elastic body on the surface of one of the electrode layers. The first button structure is configured to generate a first key signal when a force is applied to an upper wall of the first cavity and compress the upper wall of the second cavity upon application of that force. The electrode layers come into contact to generate a second key signal in response to elastic deformation of the elastic body when the force is applied.

A key structure includes a keycap, a supporting plate, a connecting element, a circuit board and an elastic element. The circuit board is disposed on the supporting plate. The circuit board includes a switch element. A first switch unit of the switch element is formed on a top surface of a first film layer of the circuit board. A second switch unit of the switch element is formed on a top surface of a second film layer of the switch element. When the keycap is depressed in response to an external force, the elastic element is subjected to deformation. Consequently, the first switch unit and the second switch unit are selectively turned on to generate a first key signal and a second key signal.

An operation device (200) for remotely operating an X-ray imaging device (1) includes an operation unit (280), a grip detection unit (240), which determines whether an operation received by the operation unit (280) is a normal operation or an erroneous operation, and a control unit (230), which transmits an operation signal corresponding to the operation to the X-ray imaging device (1). The control unit (230) transmits the signal when the grip detection unit (240) determines that the operation is a normal operation. The operation device is prevented from causing an erroneous operation of its target device.

A switching assembly intended to be joined onto a control assembly provided with an actuation member, the switching assembly comprising a body, an electrical circuit comprising two fixed contacts, the electrical circuit being able to be controlled both by a control switch of a normally-closed type and by a monitoring switch of a normally-open type, linked in series with the control switch. The monitoring switch makes it possible to monitor the correct secure attachment of the switching assembly onto the control assembly by keeping the electrical circuit open as long as the control assembly is mechanically disconnected from the switching assembly.

A fastening device for an electric control and/or indicator member, which includes a base, a fastening clamp fitted pivotably on the base about a first axis, the clamp including at least one branch having a free end designed to form at least a first bearing point against a wall, an element hinged about a second axis and interacting with the clamp to cause it to pivot about the first axis, a clamping screw for controlling the pivoting of the clamp, the clamp being configured in such a way that a first plane including the first axis and the second axis and a second plane including the first axis and the first bearing point form an angle of between 110 and 160.

A multi-pole switch assembly includes a housing, a plurality of switches, and an actuator. The switches are disposed within the housing, and each switch is coupled to receive an actuation force and is configured, upon receipt of the actuation force, to move between a first position and a second position. The actuator is disposed at least partially within the housing and is configured to at least substantially simultaneously engage, and thereby supply the actuation force to, each switch to thereby move all of the switches, with substantial simultaneity, to either the first or the second position. The actuator is rotatable to a plurality of set rotational positions to thereby vary the substantial simultaneity.

A holding device for receiving switching elements for a command and alert device, with a first housing portion in which a recess for receiving an actuator of a command and alert device is arranged, and with a second housing portion arranged on the first housing portion and which continues the recess of the first housing portion, where guide rails for guiding transmission elements are formed in the housing portions, and where the transmission elements transmit an actuation of the actuator to a switching element.

A fastening device for an electric control and/or indicator member, which includes a base, a fastening clamp fitted pivotably on the base about a first axis, the clamp including at least one branch having a free end designed to form at least a first bearing point against a wall, an element hinged about a second axis and interacting with the clamp to cause it to pivot about the first axis, a clamping screw for controlling the pivoting of the clamp, the clamp being configured in such a way that a first plane including the first axis and the second axis and a second plane including the first axis and the first bearing point form an angle of between 110 and 160.

A switch device structure serves to help in stably moving an operation rod. The switch device includes a contact fixing support assembled with an insulation case. The fixing support is formed with multiple openings. A connection board and multiple support members are correspondingly assembled in the openings. The support member has a base section and a neck section, which together define a passage. The operation rod is assembled with an elastic unit and can pass through the passage and the connection board to extend into the fixing support so as to move a wire connection assembly in the case. The switch device structure improves the shortcoming of the conventional switch device that the operation rod is apt to shake and deflect.
