ABSTRACT:
A tilt detecting device for use in various electronic apparatuses such as a watch, electronic notebook or the like. The tilt detecting device includes a projection in a part of a ball containing portion formed in an interior of an insulation case. In the insulation case, two conductive pins are disposed thereon in parallel with each other with a predetermined space, which have a large diameter portion, a small diameter portion and a step between them. In the ball containing portion, a conductive ball is contained therein, which is movable along in a longitudinal direction of the two conductive pins in the ball containing portion when the insulation case is inclined. Only when the insulation case is inclined, the conductive ball is at a position on the large diameter portions to be electrically in contact with the two conductive pins to output a corresponding detection signal.
