A switch assembly has a switch unit and a separating cap. The switch unit has a pressing element. The separating cap is attached to the switch unit and encloses the pressing element. Accordingly, glue filled into an object in which the switch assembly is mounted can be kept from attaching to the pressing element and the operation accuracy of the switch unit can be improved.

The present disclosure is directed to a contactless card including an actuation security structure that is actuated to provide authorization in accessing identifying information on an integrated circuit within the contactless card. In at least one embodiment, the actuation security structure includes a pair of conductive layers and a pair of electrodes. Ends of the pair of conductive layers overlap respective ones of the pair of electrodes. The ends of the pair of conductive layers are at and in a first elastically deformable region and the respective ones of the pair of electrodes are at and in a second elastically deformable region. An owner of the contactless card may provide authorization to access the identification information on the contactless card by applying force to both the first and second elastically deformable regions inward resulting in the ends of the conductive layers moving into electrical communication with the pair of electrodes.

A push-button comprising a first switch contact and a second switch contact which are arranged spaced apart and parallel to each other. The first switch contact is designed for establishing an electrical line connection to the second switch contact when force is applied. The push-button comprises a third switch contact which is arranged spaced apart from the second switch contact and in parallel on a side opposite to the first switch contact. The third switch contact is designed for establishing an electrical line connection to the second switch contact when force is applied. Furthermore, the push-button comprises an evaluation unit which is designed for additionally operating the first and/or the third switch contact(s) as a capacitive or inductive touch sensor.

A structure for a contact-less card, the contact-less card may include a touch sensor electrically coupled to a fixed power source or electrically coupled to an antenna. The contact-less card may include a contact-less communication controller electrically coupled to the touch sensor. The contact-less communication controller includes an integrated circuit containing card information. The integrated circuit transmits the card information based on a signal from the touch sensor. The contact-less card may include an antenna electrically coupled to the contact-less communication controller. The antenna transmits card information received from the contact-less communication controller.

A dome switch includes a first release membrane, a dome, a shim, and a second release membrane, the dome is mounted at an underside of the first release membrane, the second release membrane seals one end of a through opening of the shim, when the dome switch is mounted on a circuit board, a sealed space can be formed, ensuring that in the manufacture process of a smart card, the glue will not flow into the dome and hence the second release membrane will not be connected and adhered to the glue within the card, which may otherwise result in poor hand-tactile impression of the switch. The dome switch and the smart card with the dome switch presents good hand-tactile impression; the production rate is high and the rejection rate and the production cost are low.

Provided is a card with a built-in electronic component, which has a superior button click sensation. A card of the present invention into which is built-in a module substrate upon which an electronic component has been disposed is provided with: a front cover sheet stacked upon a side above the module substrate; an adhesion layer adhering between the module substrate and the front cover sheet; and a dome switch which is disposed upon the module substrate, and by way of the card upper surface being pressed, the switch's movable portion deforms to the module substrate side so that the electrical contact comes into tactile contact with the module substrate in order to operate the card; wherein the switch's movable portion is such that the upper surface does not adhere to the adhesion layer and the deformation to the module substrate side is unrestrained with respect to the adhesion layer.
