| PURPOSE: To provide a key board having a sure function by punching a tongue part from a contact foil in the lower part of a connecting bar, and bending the tongue part inward about 180°C in U-shape. CONSTITUTION: A keyboard has a number of keys 1 each of which has one key knob 2 and a key connecting rod 3, and a guide device 4 formed integrally to the keys 1 is connected to a support plate 5 through a pin 6 having a swollen part on the end part side. The guide device 4 has one cylindrical guide hole 8 to each key 1, and one key connecting part 3 is guided to the hole 8 in such a manner as to be movable in the direction vertical to the base 5. A pattern conductor is provided on the upper surface 9 of the support plate 5, and each key 1 has a substantially U-shape having a punched part 11 in a foil 10 to generate a foil tongue part 12 bendable 180°C from the base surface of the foil 10. The foil 10 has a pattern conductor 13 and a static contact 1, for example, by printing, and a strip operating contact 15 for bridging both the static contacts 14 in contact is installed to the tongue part 12 side opposed to the static contact 14.

| A multiple switching apparatus comprising two spring-like switching members disposed in a tandem array with each integral with its metallic support base. The central area of each of the switching members is defined by a plurality of slots formed in the support base with the length and displacement of the slots defining the force-displacement characteristics of each switching member and, accordingly, of the tandem array. The top switching member moves downward until it produces a first switching function, with further movement of the top switching member effecting movement of the second switching member such that a second switching function is produced. | ||||||

| A contact spring assembly (30) for an electronic device includes a mounting portion (31), a press spring (32), and a deformable spring (37). The press spring and the deformable spring are respectively bent from the mounting portion. The press spring resists the deformable spring. The press spring is configured to be moved along a first direction and push the deformable spring to move along a second direction different from the first direction. | ||||||

| A push switch includes a case having a bottom face, first and second fixed contacts provided on the bottom face of the case, a movable contact made of metal thin plate, an elastic body, and an operating body. The elastic body includes a cylindrical portion having a hole formed therein, a conical portion provided below the cylindrical portion, a projection located above the movable contact, and a junction portion coupling the projection to the cylindrical portion. This push switch can provide a long over-stroke after being turned on. | ||||||

| A membrane key switch includes a single resiliently deformable dielectric membrane with flaps cut therein which is formed in a housing such that the end of each flap covers a portion of the membrane. Conductive traces of the membrane are positioned so that downward flexing of the flap, caused by actuation of the switch, establishes electrical contact between a contact region on the flap end and a contact region on an uncut portion of the membrane. | ||||||

| A keyswitch arrangement including an array of switches formed on a flexible dielectric substrate wherein each switch includes a stationary conductive contact lying in the plane of the substrate and an adjacent movable conductive contactor carried on a flap cut out of the substrate and bent along a hinged line located between the contact and the contactor. The stationary contact and movable contactor are both formed on the same side of the substrate and are normally disposed in the open switch position in confronting relationship with the flap at an acute angle to the plane of the substrate. | ||||||

| 30 | Method of forming a deformed, integral switching device | US508486 | 1974-09-23 | US3950846A | 1976-04-20 | Wendell C. Johnson |
| A method of forming a switching device having a movable contact that is an integral part of a metallic support substrate and is supported above the support substrate by a plurality of spring-like legs that are also an integral part of the support substrate. One or more of the switching devices is produced by forming one or more groups of curved, unconnected radially extending slots in a metallic substrate to define support legs, plastically deforming the legs defined by the slots past their elastic limit, and then precipitation hardening the complete structure. The slots can be formed by a photomasking technique followed by an acid etch with the etch being performed from both sides of the metallic support substrate. To provide a desired tactile response characteristic, and to assure movement of a central portion of the switching device past the plane of the metallic support substrate, a portion of each of the legs defined by the slots may be removed to thin that portion of each leg. The plastic deformation may be performed in a male-female die mechanism. | ||||||
