According to various embodiments, a depressible key may be provided. The depressible key may include: a keytop; a scissors mechanism connected to the keytop; and a mechanical switch connected to the scissors mechanism.

A switch structure includes: a switch member that is deformed and receives a switch input, when force of a predetermined magnitude is applied thereto; a pressing member that presses the switch member; and an intermediate member that includes a first layer and a second layer, is interposed between the switch member and the pressing member, and is plate-like, the first layer being made of a synthetic resin and abutting against the switch member, the second layer being layered on the pressing member side of the first layer and being made of a material having a rigidity higher than the synthetic resin.

A keyswitch assembly is provided. The keyswitch assembly includes a base plate, at least one pressing mechanism disposed on the base plate, a plurality of elastic supporting members disposed on the base plate, and a keycap covering the at least one pressing mechanism and the plurality of elastic supporting members. In the embodiments, a plurality of elastic supporting members is disposed at equal intervals to support the keycap. By way of such configuration, the user experiences the same or similar hand feeling when pressing any point of the keycap. There is no difference in the pressing feel due for pressing the middle or two ends of the keycap. Meanwhile, the problem of the poor electrical conduction resulted from the deformation of the keycap may be avoided.

A switch device capable of preventing an occurrence of contact noise and wobbling of a stabilizer member to a bearing is provided. The key switch includes the stabilizer member supported between a key top and a base plate. The stabilizer member includes a first shaft portion rotatably supported on the lower surface side of the key top and a second shaft portion, which has a rotation axis parallel to the rotation axis of the first shaft portion and is rotatably supported by a bearing provided on the upper surface side of the base plate. The membrane sheet has at least a lower contact sheet having a cut-out shaped portion in a position corresponding to a position in which the second shaft portion is provided in a plane view and an upper contact sheet placed in an upper layer than the lower contact sheet to cover the cut-out shaped portion.

A button switch connected to a cap and includes a base having a pillar, a flexible acoustic member having fixing and flexible rods, a sleeve, an upward-force-applying member abutting against the sleeve and the base, a resilient arm, and a cover disposed on the base. The sleeve rotatably jackets the pillar, passes through the cover to be connected to the cap, and has first and second convex portions, first and second concave portions, and a protruding edge located between the second convex portion and the second concave portion. The resilient arm selectively abuts against a first or second position on the first convex portion. When the resilient arm abuts against the first position and the protruding edge is located above the flexible rod, the flexible rod crosses the protruding edge and then collides with the cover to make a sound when the sleeve receives an external force to move downward.

A single device operable as a controller with multiple functions includes a mounting member, a control member, a first switch, a second switch, a third switch, and a processing unit. The control member can be pressed and rotated with respect to the mounting member. The first switch, the second switch, and the third switch are located on the mounting member. The processing unit is electrically connected to all the switches. The processing unit receives a first control signal from the first switch when the control member is pressed, a second control signal from the second switch when the control member is rotated clockwise, and a third control signal from the third switch when the control member is rotated counterclockwise.

An electronic watch may include a tactile switch and/or one or more sensors for detecting rotational and translational inputs. The watch may include a display configured to produce graphical outputs that may change in response to rotational inputs, translational inputs, and/or touch inputs received at the display. The watch include a crown positioned along an exterior of the watch enclosure and a shaft coupled to the crown and extending into the enclosure. The tactile switch and/or the one or more sensors may be used to detect rotational and/or translational inputs provided at the crown.
