A push-button switch member includes: a movable contact and an operation key disposed facing the protruding side thereof, and in contact therewith or spaced therefrom. The movable contact includes: an upper contact portion disposed directly under a key body; an outer fixed portion in the upper contact portion or more outward therefrom in the radial direction, and fixed more outward in the radial direction than the key body; and a non-contacting outer portion provided more outward in the radial direction than the upper contact portion, and disposed to face in a non-contacting state another contact so as to be able to contact another contact which is disposed on an outer side in the radial direction and contacted by the upper contact portion when pushed by the key body. The non-contacting outer portion has a bottom portion for a line contact or a surface contact with another contact.

The movable contact body for a switch includes at least one movable contact having an upwardly convex leaf-spring shape, a cover member disposed so as to cover an upper surface of the movable contact, and a holding member disposed so as to face a lower surface of the movable contact, the holding member having a contact through-hole through which a top portion of the movable contact can pass.

A push switch having the contact piece including a support part supported on a base member, a movable contact part, and an interconnection part interconnecting the support part and the movable contact part. The movable contact part is movable between a position contacting a first fixed contact part and a position separate from the first fixed contact part. The contact piece is configured so that, when a pressure reception member is pushed to be moved closer to a specific surface of the base member to cause change in shape of the movable member, the interconnection part is pushed by the movable member and the movable contact part is moved along operation directions. The movable contact part located at a position facing a through hole in the operation directions. The movable contact part has a size and shape to be allowed to pass through the through hole in the operation directions.

The movable contact includes: an upper contact portion disposed directly under a key body; an outer fixed portion in the upper contact portion or more outward therefrom in the radial direction, and fixed more outward in the radial direction than the key body; and a non-contacting outer portion provided more outward in the radial direction than the upper contact portion, and disposed to face in a non-contacting state another contact so as to be able to contact another contact which is disposed on an outer side in the radial direction and contacted by the upper contact portion when pushed by the key body. The non-contacting outer portion has a bottom portion for a line contact or a surface contact with another contact.

A surface mount device switch includes a pedestal, a flexible conducting element and a metal dome. The flexible conducting element is connected with the pedestal. There is a spacing distance between the flexible conducting element and a circuit board. The metal dome is located under a pedestal conducting part of the pedestal and the flexible conducting element. When the flexible conducting element is pushed by the metal dome, the flexible conducting element is deformable in the direction toward the circuit board. Since the collision between the metal dome and the flexible conducting element is alleviated, the noise is reduced. Consequently, the comfort of operating the touchpad module is enhanced. The present invention further provides a touchpad module and a computing device with the surface mount device switch.

A control device includes a button assembly having one or more buttons and a button carrier that includes a plurality of resilient, independently deflectable spring arms. The control device may be configured as a wall-mounted keypad to control a load control device, or as a thermostat to control a temperature regulation appliance. The button carrier may be configured to prevent interference between the buttons during operation of the control device. The button assembly may be captured between a faceplate of the control device and a housing that is attached to a rear side of the faceplate. The control device may include one or more button retainers that are attached to the buttons and that are configured to align respective outer surfaces of the buttons relative to each other, and relative to the faceplate of the control device, when the buttons are in respective rest positions.

Embodiments are directed to a backlight integrated membrane for a keyboard. In one aspect, an embodiment includes a keyboard having a key cap. A feature plate may be positioned below the key cap and a membrane may be positioned below the feature plate. The membrane may include a transparent substrate optically coupled to a light emitting element. The membrane may also include electrical traces for a key switch disposed on the transparent substrate. The embodiment may further include a domed structure positioned on the membrane and configured to actuate the key switch when depressed.
