Abstract:
Analog resistance touch switches and matrix type touch switches have contacts coated with a very thin film, which in use does not form an appreciable amount of an insulating oxide, to inhibit changes in contact resistance and extend operating life.
Abstract:
A transparent membrane switch assembly (10) and mounting means (118) for mounting the assembly (10) to a cathode ray tube (CRT) (68) are disclosed. The assembly (10, 10') is comprised of two layers (12, 16) of transparent film having spaced-apart parallel double fineline conductors (20) deposited on the internal surfaces (14, 18) of both layers (12, 16). The mounting means (118) comprise extension (114) protruding from the perimeter (116) of at least one of the layers of film, and a patch of a coupled fastening assembly (120) attached to each extension (114). Each fastening assembly comprises two separable parts, an outer surface (124) of one part being attachable to a side surface of a CRT when the switch assembly is registered with the CRT face.
Abstract:
A flexible multilayered membrane switch having electrically conducting contacts comprising Ti 2-x N or Ta 2-x N, to reduce oxidation of the surfaces of the contacts.
Abstract:
In a switch structure of a sandwich construction in which an anisotropic conductor (2) is interposed between two electrodes (1) and (3), with an insulator (6) which can keep the electrode (1) and the conductor (2) insulated from each other interposed therebetween during the non-operating period, the conductor (2) and the electrode (1) of at least the operation side are made to be transparent, thereby displaying the operation contents on the electrode (3) on the non-operating side so that no displayed characters are omitted, and no contamination can occur. When the electrode (3) is also made to be transparent, the switch structure can be placed directly on the display surface of a planar display unit (10), thereby enabling a switching operation of the display positions of the display unit.
Abstract:
PROBLEM TO BE SOLVED: To provide a small-sized push-on switch used for a variety of electronic devices, operating with a click feeling in operation, and having a long life and stable contact resistance at low cost. SOLUTION: A layer of plating composed of nickel plating with a thickness of 0.3 μm as a first layer, copper plating with a thickness of 0.4 μm as a second layer, and silver plating with a thickness of 1 μm, successively from a mother material side is applied on the underside of a movable contact 10 made of an EH material of SUS301 serving as the contact face thereof.
