| 21 | Low force membrane switch | US178666 | 1988-04-07 | US4818827A | 1989-04-04 | Ralph G. Ipcinski; Douglas M. Odom |
| The invention is directed to a membrane switch comprising a first layer 30 of flexible insulating material and a second layer 50 having relatively inflexible characteristics, each layer 30, 50 having an array of conductors 40, 54 disposed thereon and defining a plurality of switch point areas over a substantial portion of the respective layers. The first sheet is transparent and carries visible symbols on the inner surface thereof formed by a first layer 36 of inks printed thereon and further includes a barrier coating over such symbols to provide contrast therefore. The first array 40 of conductors is printed on the barrier coating. The second array 54 of conductors is printed on the inflexible layer. The first and second arrays 40, 54 of conductors are connected to respective voltage sources, preferably by further arrays of conductors 42, 56 disposed over at least portions of the first and second arrays, 40, 54 the further arrays 42, 56 being of a material having a higher conductivity than the material used for the first and second arrays 40, 54. Spacer means 58 for the switch is formed by printing an array of spaced apart dots of a dielectric and insulating coating on top of at least one of the arrays of conductors in the defined switch point areas to hold the switch point areas normally apart until pressure is placed thereupon to deform the first sheet 30 and effect a switch closure between corresponding switch point areas of the arrays 40, 54. A method for making the switch is also disclosed. | ||||||

The layers are maintained together such that corresponding first and second electrical contact pads overlie one another forming switch sites. A spacer is disposed in a discontinuous pattern around the first contact pads, the spacer normally maintaining corresponding first and second contact pads spaced from each other, while permitting electrical engagement therebetween upon application of an actuation force to one of the layers at a switch site. | ||||||
| 23 | Enlarged switch area membrane switch and method | US407820 | 1982-08-13 | US4471177A | 1984-09-11 | John I. Doughty |
| A membrane switch (10) is the subject matter of this patent application. The switch (10) includes first and second switch networks connected in parallel to effect a particular function. Spacer bridges (50, 52) are interposed in the first and second switch networks to preclude inadvertent engagement of contacts on lamina surfaces (14, 16, 28, 30). The bridges (50) of the first network are either adjacent or spaced from all bridges (52) of the second network in order to insure that the application of pressure to one of two external laminae (22, 24) will activate at least one of the switch networks. | ||||||

| 33 | Membrane switch with universal spacer means | US138656 | 1980-04-09 | US4317013A | 1982-02-23 | Willis A. Larson |
| A method and apparatus for forming a membrane switch of the type having a flexible membrane, a substrate, first and second conductors formed on the membrane and substrate and spacing means disposed between the first and second conductors. The spacing means is applied to either the membrane or substrate in a uniform pattern of individual spacer areas. The spacer areas are applied in liquid form which is cured or allowed to dry. The pattern of spacer areas can be applied without regard to the location of the conductors. The size, spacing and thickness of the spacer areas allow contact between aligned first and second conductors when the exterior of the membrane is subjected to pressure. Thus the same pattern of spacer areas can be used with any arrangement of conductors. | ||||||
