    Abstract: A space key includes an elongated upper cover adapted to be touched with fingers, a lower guide plate and a spring disposed between the cover and the guide plate. A stabilizer rod having a center stem portion is rotatably received by the cover and Zshaped end portions each pointed end of which is pivotably received in a corresponding notch formed in upright portions of the guide plate, whereby upon depressing the upper cover at any portion thereof the cover moves down without inclination toward the guide plate to reliably actuate a switch disposed under the guide plate.

    Abstract: A rectangular case supports a spring biased reciprocating lever of rectangular, block form by engagement of its ends with opposed parallel guide grooves within the sidewalls of the case, the width of the sidewalls at the groove contact area and respective grooves being different for orientation of the lever. Plural reed switches are mounted within a recessed portion of a rectangular protecting frame with a hole within the bottom of the frame receiving one reed switch lead and the lead captured within the groove at the rear of the frame. Frame pits, of corresponding size, defined by strips projecting inwardly from the sidewalls of the case receive the frames. Cylindrical cavities within the lever and flexible stops on opposed sides at the top and bottom of the cavity openings permit insertion and retention of cylindrical permanent magnets within the lever.

    Abstract: A switch has a substrate with a plurality of conductor pairs on it. A resilient cover is disposed over the substrate and has depressible areas aligned with the respective conductor pairs. Conducting contact pieces are mounted on the cover below each of the depressible areas, but normally spaced above the pairs. Upon pressing down a given depressible area, the corresponding contact piece moves to engage the conductor pair associated therewith, and thus closes the circuit between them.
