摘要： In an ergonomic keyboard comprising at least two housing sections with separate key pads wherein the two housing sections are interconnected by a joint permitting pivoting and also tilting of the two housing sections relative to each other, the joint comprises a coil spring which extends between, and is connected to, the two housing sections at the end of the housing sections remote from an operator so as to form a universal joint between the two housing sections, and a sector-shaped indexing plate is mounted with one end firmly to one of the housing sections and extends into the other housing section so that it bridges any gap formed between the two housing sections when they are pivoted apart, and the other housing section has a guide pin projecting into a partial circular guide slot formed in the indexing plate and having a center of curvature coinciding with the universal joint pivoting center for guiding the two housing sections relative to each other.

摘要： A cursor control device moves from a precise zero rest position to define x-y coordinates for moving a cursor on a computer screen. When an actuating force is removed, the deflected control device is precisely returned to its zero rest position by operation of springs. The device provides relative cursor position data by reference to the zero rest position. The position data is converted to electrical signals which are utilized to position the cursor on the screen.

摘要： A key module for a membrane switch keyboard has a flat spring running diagonally to the key housing on the bottom side which, with the aid of a plunger, is bent for the operation of membrane contacts. The flat spring with one free end is inserted into a slot which is open toward the top and permits an adjustment of the flat spring by pressure loading on the free end or on the bottom side against the lower section of the flat spring, which is adjacent to the bent free end. The free end of the flat spring is rigidly retained in a slot at the key housing. For the adjustment of the operating force a compression spring is arranged inside the plunger and is supported against a cross-piece running over the flat spring.

摘要： A low profile switch key has a base which slidingly supports a pushbutton. The pushbutton is slidingly engaged with a plunger body by a lost motion connection. The plunger body carries cams which control the flexing of contactors to make and break conductive connections with adjacent stationary contacts. A coil spring biases the pushbutton upwardly to its rest position. The sliding lost motion between the pushbutton and plunger body allows the pushbutton to slide by itself over an initial pretravel interval when it is pressed. At the end of the pretravel interval, the pushbutton strikes the plunger body and carries the body downward to complete the key stroke. The plunger body resists sliding movement and therefore provides a perceptible pressure point which indicates actuation of the switch. The stationary contacts and associated overlying cams are interlocked when the pushbutton is depressed to provide a relatively low switch profile with respect to the length of the key stroke.
