摘要： A multidirectional switch and an operation unit containing the switch, to be used for controlling an automobile air-conditioner, etc. Respective operating areas of an operation body are positioned at the middle area between push button switches. Therefore, a pressing force applied on an operating area causes a swaying motion with a swaying body and push means of swaying body push two switching contacts at substantially the same time, resulting in the electrical connection/disconnection. The configuration of the present invention eliminates such constituent components as coil spring, supporting pin, etc., yet it provides a inexpensive multidirectional switch that has a superior operational feeling with a less number of constituent components.

摘要： A backlighted illuminated keyboard including a printed circuit board on which is mounted in a central location a single lamp easily replaceable from the backside of the board and which extends into a clear plastic light diffuser over which an overlay is disposed and a bezel is provided to define key areas in the translucent overlay such that the single lamp disperses light energy through the diffuser to light up the entire overlay. The single lamp is mounted in a socket formed in the printed circuit board and held in place by a swivel arm which can be swung to one side to allow ease of removal of the lamp.

摘要： An array of pushbuttons is formed as domes in a plate of springy material. The domes behave in the manner of the base of an oilcan-snapping in when pressure is applied to close pushbutton contacts and snapping out to open the contacts when pressure is released.
