An electronic switch includes a rubber sheet that includes a first surface, a second surface opposite to the first surface, and a convex portion on the first surface. The convex portion of the rubber sheet includes a semispherical shape.

A slim-type key structure includes a keycap, a base plate, a scissors-type connecting element, a membrane circuit board, a metal dome and a positioning plate. The keycap can be pressed. The scissors-type connecting element is located under the keycap. The membrane circuit board is disposed on the base plate. The metal dome is disposed on the membrane circuit board. In response to a pressing force, the metal dome is subjected to a compressed deformation to press the membrane circuit board. When the pressing force is released, a restoring force is generated and the metal dome is restored to an original shape in response to the restoring force. The positioning plate includes a pressing post. The pressing post is aligned with a center of the metal dome and a center of the keycap. The positioning plate is fixed on the metal dome through an adhesive.

A contactor device includes: a first body substrate; a second body substrate; a flexible membrane connected to the first body substrate and second body substrate, wherein the second substrate body is movable relative to the first substrate body by flexure of the flexible membrane; an electrical contact member carried by the second substrate body; a microfluidic-channeled substrate coupled to the first body substrate, the microfluidic-channeled substrate having a chamber and a microfluidic channel in fluid communication with the chamber; and a 3-dimensional flexible membrane enclosing the chamber, wherein the 3-dimensional flexible membrane flexes toward the second body substrate when a fluid pressure is applied to the chamber through the microfluidic channel whereby a force or a movement is transferred to the second body substrate by the 3-dimensional flexible membrane.

An electronic device includes a pressing member having plural protruding pressing parts, a first opening-formed member having plural first openings into which the plural pressing parts are inserted so as to individually protrude, a second opening-formed member having plural second openings into which the plural pressing parts are inserted so as to individually protrude, and a positioning member positioning the pressing member, first opening-formed member, and second opening-formed member so that the plural pressing parts are disposed at positions where the plural pressing parts are inserted in the plural first openings and plural second openings.

A keyboard device includes an upper housing, a conductive membrane, a key top including a bottom surface and an actuator disposed on the bottom surface, a lower housing and a soft elastic element located on the conductive membrane, wherein the actuator penetrates the upper housing, and the soft elastic element has an engaging part to engage with the key top such that the key top is prevented from being separated from the soft elastic element when the key top rebounds.

Input device configurations are described. In implementations, an input device includes a sensor substrate having a capacitive sensor to detect proximity of an object that contacts the input device. The input device also includes a flexible contact layer spaced apart from the sensor substrate, where the flexible contact layer is implemented to flex and contact the sensor substrate responsive to pressure applied by the object to initiate an input to a computing device. The flexible contact layer can include a force concentrator pad that is designed to cause pressure to be channeled through the force concentrator pad to cause the flexible contact layer to contact the sensor substrate to initiate the input.

An electronic apparatus is disclosed. An electronic apparatus comprises a housing, a press switch, an operation button, a bonding member, and a watertight member. The housing has a front surface on which a cover panel is located and has a side surface in which a through hole is formed. The press switch is located in the housing and has a press surface facing the through hole. The operation button is a button for pressing the press switch. The bonding member has watertightness and has a portion that surrounds a circumference of one opening of the through hole. The watertight member is located between the press switch and the operation button and is bonded to the housing with the bonding member such that the watertight member blocks the one opening.

A key structure includes a key, a key sheet and a supporting portion. The key displaces in a direction. The key sheet is disposed at a side of the key toward which the key displaces and comprises a sheet base portion and a contacting portion that displaces in the displacing direction of the key in accordance with a displacement of the key. The supporting portion is disposed between the key and the sheet base portion and supports one end portion of the key by contacting a member disposed opposite to the supporting portion while the other end portion of the key displaces in the displacing direction of the key.
