Abstract
An improved keyboard structure consists of a lower plate, a membrane circuit, an upper plate, a bridge means, an elastic element and a key cap. The lower plate has a set of symmetrical first latch sections and a set of retaining sections formed at selected locations corresponding to the first latch sections. The upper plate has a set of symmetrical second apertures corresponding to the first latch sections and a set of symmetrical second latch sections corresponding to the second apertures. There are openings in front of the second latch sections for housing the retaining sections. The bridge means has a first pivotal end insertable in a biased manner into a space formed between the second latch section and the retaining sections and a second pivotal end latching to the first latch sections such that the bridge means can be assembled on the upper plate and the lower plate in single direction. The upper plate may be pushed to move the second latch sections away from the first pivotal end for removing the bridge means.
