US 2010/0142331 A1 · ROTARY SWITCH AND ELECTRONIC TIMEPIECE

Abstract

A rotary switch of the present invention includes an operating member, a magnet member, and a magnetic sensor. The operating member is operable to move from outside of the case to first and second positions in the axial direction and operable in a rotation direction, and an engaging section is formed in a predetermined area thereof. The magnet member is provided in such a manner not to move in the axial direction of the operating member, and has formed therein an engaging hole. The magnetic sensor detects rotation of the magnet member. In this rotary switch, when the operating member is moved in the axial direction, the engaging section moves inside the engaging hole with the engaging section being engaged with the engaging hole, and when the operating member is rotated, the magnet member rotates therewith.

Dependent claims

A rotary switch comprising:

an operating member that is operable to move from outside of a case to a first position and a second position in an axial direction and operable in a rotation direction, where an engaging section having a non-circular cross-sectional shape is formed in a predetermined area;
a magnet member that is provided in such a manner not to move in the axial direction of the operating member, and has formed therein an engaging hole into which the engaging section of the operating member is inserted;
and
a magnetic sensor that detects rotation of the magnet member;
wherein when the operating member is moved in the axial direction, the engaging section of the operating member moves inside the engaging hole of the magnet member with the engaging section of the operating member being engaged with the engaging hole of the magnet member, and
when the operating member is rotated, the magnet member rotates with the operating member.

An electronic timepiece comprising:

an operating member that is provided in a through-hole of a timepiece case in such a manner to be operable to move to a first position and a second position in an axial direction and operable in a rotation direction, where an engaging section having a non-circular cross-sectional shape is formed in a predetermined area;
a magnet member that is disposed inside the timepiece case in such a manner not to move in the axial direction of the operating member, and has formed therein an engaging hole into which the engaging section of the operating member is inserted;
and
a magnetic sensor that detects rotation of the magnet member;
wherein when the operating member is moved in the axial direction, the engaging section of the operating member moves inside the engaging hole of the magnet member with the engaging section of the operating member being engaged with the engaging hole of the magnet member, and
when the operating member is rotated, the magnet member rotates with the operating member.
