Various processes for creating mirrored features are discussed herein as well as devices that include the mirrored features. One embodiment includes a button having a transparent layer and an opaque layer coupled to the transparent layer. A portion of the transparent layer extends through the opaque layer so that the portion of the transparent layer is flush with a back surface of the opaque layer and generally has a shape of a desired feature. The button also includes a reflective object positioned so that it may be seen through the transparent layer.

Systems and methods for providing input component assemblies for dome switches are provided. In some embodiments, an input component assembly may include a first conductive contact pad coupled to a first board of a switch, a second conductive contact pad coupled to a second board of the switch, and a layer of conductive adhesive between the first conductive pad and the second conductive pad, where the layer is operative to provide a seal for the switch.

Systems and methods for providing input component assemblies for dome switches are provided. In some embodiments, an input component assembly may include a contact area coupled to a circuit board for a switch, a conductive covering for enclosing the circuit board, and a dome positioned over the conductive covering, where the dome is operative to close at least one circuit of the switch when the dome is depressed towards the conductive covering.

A push switch includes a case, a fixed contact member, a moving contact member, a first protective sheet, and a second protective sheet. The case has a first surface with a recess opened and a second surface opposite from the first surface. The fixed contact member includes a fixed contact in the recess and a terminal on an outer surface of the case. The moving contact member is in the recess and includes a moving contact to contact with the fixed contact through a press operation. The first protective sheet is provided for the first surface to cover the recess. The second protective sheet covers the second surface. The first protective sheet is welded to the first surface with a first welded portion surrounding an entire circumference of the recess. The second protective sheet is welded to the second surface with a second welded portion.

An electric device includes an electric component and a housing having a lower housing part and an upper housing part. The electric component is supported on the lower housing part. The lower housing part and the upper housing part surround a housing volume in which the electric component is sealingly encased. A weld is formed between the upper housing part and the lower housing part. One of the lower housing part and the upper housing part has a protrusion welded to the other one of the lower housing part and the upper housing part. A gap is disposed between the lower housing part and the upper housing part, the gap extending radially from the protrusion to an outside of the housing. A solidified molten material from the weld is at least partially received in the gap.
