| 32 | Keyboard switch assembly with improved operating means | US36612873 | 1973-06-01 | US3856998A | 1974-12-24 | SIMS D |
| The disclosure relates generally to key assemblies employed in electrical switch operating keyboard devices and more particularly to the assembly of parts forming an individual depressible key of such a keyboard. Each key assembly is composed of parts cooperatively interfitting to provide both a low profile for the keyboard as well as a bifurcated electrical contact provision. Included in each key assembly is a pair of coiled springs of different diameters which are coaxially and overlappingly related to one another. The smaller diameter spring of the pair is a double rate spring and as such is formed with two longitudinal sections of different helical pitches for conveying forces employed to depress the key to the switch associated with the assembly to effect closure of the same, as well as for substantially reducing if not eliminating a detrimental contact ''''bounce'''' encountered in the operation of such assemblies. The force transmitting spring member acts through a terminal member shaped to provide a teetering motion in conjunction with the desired bifurcated action for assuring closure of the contacts. The assembly is composed of parts formed mainly of plastic material molded to shape and as such provides a durable, light-weight, and low cost structure.

| 35 | Strong current static contact device for high voltage earthing switches | US14375054 | 2013-10-14 | US09384909B2 | 2016-07-05 | Chunwei Jiang |
| The present invention is the field of electrical elements, related to the technology for improving the connection performance of the static contact device for strong current in high voltage switches, especially for a type of static contact device for strong current in high voltage earthing switches. It includes a base, with two Contact Pieces standing face-to-face on it and vertical to its upper end surface. Outside each of the two Contact Pieces, there is a supporting plate, the lower end of which is firmly fixed on the base. Two groups of coaxially stacking Belleville springs are set between each supporting plate and the contact piece on the same side. By way of setting two groups of Belleville springs on one side, the present invention enlarges the contact surface between the Contact Piece and the moving contact blade, effectively reinforcing the gripping for each other. Compared with the scheme in which a single group of Belleville springs is used on one side with equal pressure, this new scheme can prolongs the products' service life as well as ensure good connection performance of the static contact. | ||||||

| A membrane switch is actuated by pressure transmitted from a movable key member through two coaxial springs connected end-to-end. A first of the two springs is held by the key member in a partially strained state requiring an initial force to strain it further. The second spring, smaller in diameter and stiffer than the first, has a free end at which force is applied to the membrane switch. As a top of the key member is pressed, the free end of the second spring moves toward, touches, then presses the membrane switch. Force builds rapidly with displacement in the small spring until it reaches the initial force under which the first spring is retained. This initial force is made roughly equal to the force required to actuate the membrane switch. After that point, the force-displacement characteristic is that of the two-spring combination, which is less stiff than the second spring alone. Thus, long key travel is permitted while the actuation force is reached early in the displacement of the key member. In one embodiment, a resilient boot, covering a key stem of the key switch, buckles when the key is pressed to provide a click-like feedback to an operator. | ||||||
