Abstract
A rotary switch includes an operating member, a magnet member, and a magnetic sensor. The operating member is operable from outside of a case to move to first and second positions in an axial direction and is rotatable. The magnet member is provided in such a manner that the magnet member does not move in the axial direction of the operating member. The magnetic sensor detects rotation of the magnet member. An engaging section is formed in a predetermined area of the operating member, and an engaging hole to receive the engaging section is formed in the magnet member. 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.
