Multi-directional operation switch and multi-directional input device using the same
Abstract:
In a multi-directional operation switch, an operating disk, upon being pressed at its upper side, tilts to depress a elastic pressing member, thus making hard rings of the driving member to press a resistor sheet sequentially. This operation allows resistor layers beneath the resistor sheet to directly contact annular electrically conductive layers facing the resistor layers in a desired sequence, respectively. The multi-directional operation switch has a reduced height and can produce a number of switching signals according to desired angular directions of switching operations.
