Abstract (en)
[origin: EP1478001A1] The present invention provides a navigation switch apparatus with simple construction capable of operating in eight directions in total including longitudinal, lateral and diagonal directions. The navigation switch apparatus has a printed circuit board (1) provided thereon four conductors (2a, 2b, 2c, 2d) shaped a circle with small spaces (3a, 3b, 3c, 3d) between each pair of four conductors so that whole the conductors are shaped a doughnut-like. Further, a cap-shaped body (5) arranged opposite to the printed circuit board (1) is provided with short-circuiters (6a, 6b, 6c, 6d) capable of making contact with the respective four conductors (2a, 2b, 2c, 2d) when a navigation lever (11) is operated in the longitudinal, lateral and diagonal directions. Each conductor is formed with two opposed comb-shaped conductive layers (4a, 4b) such that the central portion of the one conductive layer is in a diametrically directed comparatively-coarse comb shape, whereas both the end portions of the other conductive layer are in a circumferentially directed comparatively-fine comb shape, and the cap-shaped body (5) has a thin-walled portion on its outer periphery. Thick-walled portions (8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h) extending in the longitudinal, lateral and diagonal directions, thus forming a substantially regular octagon as a whole, are formed in the vicinity of the thin-walled portion. <IMAGE>
