<P>PROBLEM TO BE SOLVED: To provide a switching device capable of minimizing a load and operating stably for a long time, and a rotational position detecting device and an electronic time-piece. <P>SOLUTION: The switching device 1 of the electronic time-piece 3 has a switch body 30 which is rotatable around an axis perpendicular to a main plate 11 and movable in the axial direction, and is provided with a plurality of legs 32, 33 projecting towards the main plate, and a switch contact portion 35a projecting in a direction opposite to the main plate at an end on the opposite side to the main plate of one of the legs, an elastic biasing means 60 provided with a spring portion 61 for applying an elastic force to the switch body so that the main-plate side ends of the legs of the switch body come in touch with the surface of the main plate, operating wall portions 40 including projecting wall portions 41 formed on the surface of the main plate so as to displace the switch body perpendicularly to the extending surface of the main plate, and a circuit-side contact 50 counterposed to the main plate so as to touch the switch contact portion, when the switch body is displaced in the direction perpendicular to the extending surface of the main plate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
