A multipolar switch includes a first electrical contact zone connected to a first electrical circuit, and a second electrical contact zone connected to a second electrical circuit. In addition, a first part made from an electrically conducting material is arranged on and at a distance from the first electrical contact zone, and a second part made from an electrically conducting material is arranged on the first part. An electrically insulating layer is arranged between the first part and the second part so as to electrically insulate them from one another. So configured, the first part is configured to be elastically deformed when being mechanically solicited in an actuating direction of the multipolar switch, and the second part is configured to be elastically deformed or be displaced in the actuating direction of the multipolar switch, between a rest configuration and an activated configuration.

A membrane circuit structure includes a first film substrate and a first circuit layer. The first circuit layer is disposed on the first film substrate. The first circuit layer contains first conductive silver paste and second conductive silver paste. The first conductive silver paste has a first impedance value. The second conductive silver paste has a second impedance value. The first impedance value is 10 to 15 times the second impedance value.

An article comprising a bulk metallic glass skin having one or more functional features integrated therein is described and a method of forming the same is described. The one or more functional features exhibit a variation in stiffness between the one or more functional features and the bulk metallic glass skin that is defined by an applied force over an achieved deformation. The stiffness of each of the one or more functional features is at least 1000 times less than an average stiffness of the bulk metallic glass skin.

A keycap includes a keycap main body and multiple metal oxides. The metal oxides are doped in the keycap main body and forms an opaque region and a light-transmitting region in the keycap main body. The light-transmitting region is formed by irradiating a portion of the opaque region with an energy beam. A transmittancy of the light-transmitting region is greater than a transmittancy of the opaque region. A manufacturing method of the keycap is also disclosed.
