A heat destructive disconnecting switch, comprises a first conductive member, a second conductive member, a movable conductive member, an overheating destructive member, an operating component, and a second elastic member. The movable conductive member conducts electricity to the first conductive member and the second conductive member. A first elastic member and the second elastic member act on an operating member. The first elastic member is compressed and provided with a first elastic force, and the second elastic member is provided with a second elastic force. When the overheating destructive member is destructed due to overheating, the first elastic force is diminished or vanishes, causing the second elastic force to be larger than the first elastic force. Consequently, the movable conductive member disconnects the current conducting state between the first conductive member and the second conductive member, thereby achieving a protective effect from overheating.

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 keyswitch structure includes a base plate, a keycap, a first support, and a second support. The keycap is located above the base plate. The first support is connected to and between the keycap and the base plate and has an upper connection portion, a lower connection portion, and a protruding limitation portion. The upper connection portion is located between the lower connection portion and the protruding limitation portion. The first support is rotatably connected to the keycap and the base plate through the upper connection portion and the lower connection portion respectively. The protruding limitation portion is located close to and under the cap body. The second support is connected to and between the keycap and the base plate. The keycap moves up and down relative to the base plate through the first support and the second support.

An overheating destructive switch, comprising: a first conductive element, a second conductive element, a movable conductive element, an overheating destructive element, an operating component, and a second elastic element. The movable conductive element connects the first conductive element and the second conductive element. A first elastic element and the second elastic element act on an operating element. The first elastic element is compressed and has a first elastic force, and the second elastic element has a second elastic force. The first elastic force is greater than the second elastic force under in a normal state. When the overheating destructive element is destroyed due to overheating, the first elastic force is reduced or lost, such that the second elastic force becomes greater than the first elastic force. The movable conductive element is consequently disconnected from the first conductive element and the second conductive element, thus achieving protection against overheating.
