A mobile device and a method of manufacturing a mobile device are disclosed. An aspect of the present invention provides a mobile device, which includes: a multi-layer circuit board including a plurality of circuit pattern layers and a plurality of dielectric layers and having a cavity formed on a lateral surface thereof toward an inside thereof; an electrode pad laminated in the cavity and configured to be electrically connected with the circuit pattern layers; and a conductive switch formed on an external peripheral portion of the cavity of the multi-layer circuit board in such a way that the conductive switch is separated from the electrode pad and is contactable with the electrode pad by an external force.

Embodiments of the present disclosure provide a pedal anti-skid pad assembly and a scooter. The pedal anti-skid pad assembly is configured to be install on a pedaling portion of a scooter. The pedal anti-skid pad assembly includes an anti-skid pad body and a membrane switch. The anti-skid pad body has a first surface for being fixedly connected with the pedaling portion. The membrane switch is fixed on the first surface of the anti-skid pad body. The membrane switch is configured to electrically connect with an electric drive apparatus of the scooter, and the membrane switch is configured to switch on when receiving external force to trigger the electric drive apparatus to start.

A shelf bracket is provided. The shelf bracket includes a shelf member and opposing side flanges extending from a back plate. A front flange extends from each of said opposing side flanges. The back plate, shelf member, side flange, and front flange define a cavity configured to receive an enclosure, such as by moving the enclosure in a vertical direction in and out of engagement with the cavity. The shelf member defines a bottom limit of the cavity such that movement of the enclosure into the cavity is limited to a first vertical direction and movement of the enclosure out of the cavity is limited to a second vertical direction, the second vertical direction being diametrically opposed to the first vertical direction. A support flange is optionally included, which is configured to engage with a support structure so as to provide support for the shelf bracket.

A backlight apparatus, used in an illuminated keyboard, includes a light-guiding plate, a light-shielding membrane, a light-reflecting sheet, a plurality of first translucent glue bodies, and a plurality of second translucent glue bodies. The light-guiding plate has a plurality of through holes. Each of the first translucent glue bodies corresponds to one of the through holes. Each first translucent glue body is placed on a front surface of the light-guiding plate, and surrounds a respective circumference of the corresponding through hole to bond the light-shielding membrane thereabove and the light-guiding plate therebelow. Each first translucent glue body has a respective breach. Each of the second translucent glue bodies corresponds to one of the first translucent glue bodies, is placed via at least one portion thereof in the breach of the corresponding first translucent glue body, and bonds the light-shielding membrane thereabove and the light-guiding plate therebelow.

A control device is provided. A membrane switch of the control device is specially designed. A cured ink member is formed on a surface the upper film layer facing the lower film layer or a surface of the lower film layer facing the upper film layer by using a UV printing process. Due to the ink member, a specified gap or distance between the upper film layer and the lower film layer can be maintained when they are not contacted with each other or when the membrane switch is not triggered.

A method of making an actuator switch is disclosed. One method including: receiving a threshold amount of pressure on a top surface of a flexible film; in response to receiving the threshold amount of pressure, contacting a first electrode with a second electrode; in response to receiving the threshold amount of pressure, generating i) a first capacitive connection between a row electrode and the second electrode and ii) a second capacitive connection between a column electrode and the second electrode; in response to the first electrode contacting the second electrode, generating, by a piezoelectric actuator, haptic feedback; and in response to the generating the first capacitive connection and the second capacitive connection, providing an input detection signal.

A key switch device includes a base, a button mounted on the base so as to be contactable and separable, an elastic body disposed between the base and the button and configured to urge the button in a direction away from the base, and a linear reinforcement member provided on the button and configured to prevent the button from being inclined when the button is operated in a direction toward the base. An outer surface portion of the button includes a recessed support portion in which a part of the linear reinforcement members is disposed.
