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.

A method for selectively restricting movement of an appliance position switch from a closed position to an open position includes positioning the pin within a channel of a body portion of a switch retention device and moving the body of the switch retention device in a first direction into an opening in a face of the appliance within which the pin is moveable from the open position to the closed position. Such movement is carried out to cause movement of the pin in the first direction toward the closed position. The method further includes continuing to move the switch retention device in the first direction such that a cap thereof contacts the face, and a tab extending outwardly from the body engages with the opening to retain the switch retention device in the opening and the pin in the closed position.

An electronic device includes a host, a display, a sliding plate, and a keyboard. The host has an operating surface. The display is pivoted to the host. The sliding plate is slidably disposed in the host, where the display is mechanically coupled to the sliding plate, and the sliding plate includes a plat portion and a recess portion that are arranged side by side. The keyboard is integrated to the host. The keyboard includes a key structure, where the key structure includes a key cap and a reciprocating element, and the key cap is exposed from the operating surface of the host. The reciprocating element is disposed between the key cap and the sliding plate and has a first end connected to the key cap and a second end contacting the sliding plate. The second end is located on a sliding path of the plat portion and the recess portion.

A hinge device can detect an open angle and an opening/closing angular velocity with high responsiveness and simple configuration. The hinge device enables rotary motion of a main-body chassis and a display chassis, and includes a first chassis shaft non-rotatably provided with respect to the main-body chassis, a second chassis shaft non-rotatably provided with respect to the display chassis, a cylindrical body into which the first chassis shaft is inserted to rotate with rotary motion thereof, a ring-type magnet non-rotatably fixed to the cylindrical body, a sensor that detects a movement of the magnet associated with the rotary motion from the change of magnetism, and a controller that reads a signal from the sensor to calculate an open angle and an opening/closing angular velocity.

A slidable magnetic switch for controlling the electronic functions of an appliance on the Jewish Sabbath is disclosed herein. A housing with an integrated magnetic slider is permanently attached to the appliance surface directly adjacent to and above its embedded magnetic sensor, whereupon the magnetic force of the extended slider opens the sensor's electrical circuit and disables various auxiliary electronic functions whose operation is prohibited on the Sabbath. The slider is pushed back inside the housing after the Sabbath ends, allowing the sensor's electrical circuit to return to its regularly closed position, enabling the appliance's electronic functions for normal weekday operation. A timer alarm switch mounted within the housing provides an audible reminder to manually activate the magnetic switch each week before the Sabbath begins, or alternatively, to automatically extract the slider from the housing before the Sabbath commences, and retract the slider into the housing after the Sabbath concludes.

A position switch retention device for use with an appliance including a body defining a first end, a cap extending outwardly from a second end of the body opposite the first end, and a first tab extending from a side of the body. The first tab defines a ramp extending away from the body to an edge directed toward and spaced from the cap.

A keyboard device includes a supporting plate, a keycap, a stopping structure and a switching module. The stopping structure is arranged between the supporting plate and the keycap, and located near an outer edge of the keycap. The switching module is located under the keycap and connected with the stopping structure. While the switching module is moved relative to the supporting plate in a second axial direction, the stopping structure is correspondingly moved. When the switching module is in a first status, the stopping structure is located near the outer edge of the keycap. When the switching module is in a second status, the stopping structure is moved to a position under the first outer edge of the keycap to stop the movement of the keycap.

Examples disclosed herein relate to a power button. Examples include a device including a power button to activate a power supply of the device. A controller of the device to determine whether the device is in disabled power event state and to disable the power button when the device in the disabled power event state.
