42 Membrane keyboard switch assembly having selectable tactile properties US187904 1980-09-17 US4362911A 1982-12-07 Ronald J. Sears; Jack R. Gross
A "membrane"-type keyboard includes a resilient foam layer having an array of holes therein with the layer being sandwiched between first and second flexible membranes having electrical conductors thereon which are arranged to complete a circuit associated with a hole when the first and second membranes are moved toward each other. Embodiments including dome-shaped areas in the first flexible membranes provide for "tactile feedback" and additional foam layers enhance the operating characteristics of the embodiments. The method generally entails determining the operating parameters of a desired keyboard and simply changing the relative density and/or thicknesses of various layers and flexible membranes in the keyboard to obtain radically variable paremeters, as for example, the location of the "makepoint" of the switch at various positions between the start and end of "key travel."
43 Key operated switch with depressible bridging contact layer of matted unwoven electrically conductive fibers US3745287D 1971-10-01 US3745287A 1973-07-10 WALKER W
A key operated diaphragm type switch comprising a printed circuit board base having conductors thereon, a flexible sheet of non-conductive material supported in taut condition over the base and having an opening therein aligned with adjacent terminal portions of certain of the conductors, and a layer of unwoven matted metal fibers on the order of .10 in. thick overlying the sheet. Upon depression of the key, the underlying portion of the metal fiber layer and the flexible sheet are pressed toward the base. The portion of the metal fiber layer underlying the key is deformed through the opening in the flexible sheet and into bridging contact with the conductors to close the switch.
44 Monolithic keyboard and method for making same US3627927D 1969-11-24 US3627927A 1971-12-14 SCHMITZ HERBERT E; BLEAU ROBERT A
A monolithic keyboard constructed in layers with inexpensive materials and which has no conventional moving parts is disclosed. In one embodiment, the layers include a bottom or first layer of conductive material, a second layer of spongy material with holes cut therein, and a third layer of flexible printed circuit. This flexible printed circuit includes a sheet of insulating material with conductive pads placed thereunder in registration with the holes in the spongy material. Key symbols are etched on or printed over the conductive pads thereby indicating the placement of the keys. Depressing the key causes contact to be made between the respective pad and the first layer of conductive material. The spongy material gives the operator the ''''touch'''' of a standard typewriter keyboard.

PURPOSE: To easily separate a keyboard from a circuit substrate for sealing a key, preventing liquid from flowing into the circuit substrate, completely cleaning and sterilizing the key. CONSTITUTION: Plural flexible elastic domes 32 corresponding to the keys 16 and semitransparent thin films 20 which are arranged between a panel and a substrate 24 and which form liquid resistant seals between the panel and the substrate 24 are provided. Thus, liquid is prevented from flowing into the substrate 24 even if it drops from the key 16. Conductive surfaces 76 which correspond to the respective flexible elastic domes 32 and are arranged on sides facing to the substrate 24 of the semitransparent thin film 20 are provided. When the key 16 is depressed, the corresponding dome 32 is deformed and the conductive face 76 belonging to the corresponding dome 32 is pressed to one corresponding contact land 78. Thus, an electric operation corresponding to a key 16 operation can securely be realized. COPYRIGHT: (C)1995,JPO

1298290 Retractive switches INTERNATIONAL BUSINESS MACHINES CORP 21 Dec 1970 [23 Jan 1970] 60508/70 Heading H1N A switch comprises a fixed contact 27; a movable contact 24 mounted on a diaphragm 23 and an actuating member 20 located on the other side of the diaphragm to the contacts and having a projection 21 facing the diaphragm whereby on depression of the actuating member which is of elastic material the projection urges the contacts into engagement. The contacts 24, 27 are gold-plated copper laid on polyester diaphragms 23, 30; a separator sheet 25 having holes aligned with the contacts is placed between them. The actuating member is of solid neoprene and besides projections 21 has further, shorter projections 22 which limit travel and prevent damage to the contacts or diaphragm 23. Above the actuating member rests a thick block 16 of soft closed-cellular neoprene and above this, resting on a rigid aluminium frame 15 is an actuator sheet 10, 14 of polyurethane elastomer having raised portions 11 marked with indicia (Fig. 2, not shown). The sheet 10 can be readily removed and replaced by another bearing alternative indicia. The block 16 gives the switches a suitable "feel" and allows pretravel and overtravel. The stop projections 22 may be arranged in a circle or a square depending upon the shape of the raised operating portions 11; they may be discrete projections or a continuous ring surrounding the projection 21. More than one projection 21, each operating a pair of contacts, may be associated with a group of projections 22 below a single portion 11.

A process is provided for characterizing a tactile response of a first mechanical actuator (e.g., button) based on a back off distance. The first mechanical actuator may include a plunger, a dome-shaped flexible membrane, and an electrical contact, all aligned with each other so that a contact signal is generated when the flexible membrane touches the contact. The plunger can be moved a first distance towards the contact until the contact signal is generated at a contact point. Then the plunger can be backed off a second distance from the contact point. This second distance may be called the “back off distance”. The particular feel of the first mechanical actuator can then be correlated to a particular back off distance. This process can be repeated a number of times to classify a number of different “feels” for the first mechanical actuator based on a number of different back off distances.

57 Leveled touchsurface with planar translational responsiveness to vertical travel US13323292 2011-12-12 US08309870B2 2012-11-13 Cody George Peterson; Douglas M. Krumpelman; Michael D. Levin
Described herein are techniques related to a leveled touchsurface with planar translational responsiveness to vertical travel. Examples of a touchsurface include a key of a keyboard, touchpad of a laptop, or a touchscreen of a smartphone or tablet computer. With the techniques described herein, the touchsurface is constrained to remain in a level orientation during planar translational movement between depressed and unpressed positions along a diagonal line with respect to a vertical axis. Also, with the techniques described herein, a planar-translation-effecting mechanism imparts a planar translation to the touchsurface while it travels vertically (e.g., downward) as the user presses the touchsurface. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

A keypad for a mobile device having a housing comprises a plurality of keys coupled to the housing. Each of the keys has means for making the selection of smaller key sizes easier for a user. The keys may incorporate a flexible or resilient upper part, or be configured to transform to a larger surface area upon the application of pressure. The keys may be configured to rotate away from a selected key. The keys adjacent a selected key may be configured to lock mechanically or electrically. The keys may have multiple parts that are movable relative to one another. The upper part of the key may include a fluid, with a selection rod positioned inside the upper part to enter the fluid.
