Abstract: A rotary switch device includes a terminal base to which a center portion contact and a fixed contact member are fixed, a movable contact member, and a support portion. The movable contact member includes a contact protrusion part which is pressed in contact with the center portion contact at one end of the movable contact member and a first contact surface which is in contact with the fixed contact member at another end of the movable contact member, and which is operated to rotate around the center portion contact so as to short-circuit between the center portion contact and the fixed contact member at a conductive rotation position.

Abstract: An object of the present invention is to provide a photosensor unit with a structure which is simple and does not lower the detection accuracy. Provided is a photosensor unit configured such that reflected light of detection light emitted from one or more light emitting elements 2 housed in a unit case 1 to the outside of the unit case 1 is detected with a light receiving element 4 mounted on a mounting board 3, the reflected light being reflected from a detection region set on the outside of the unit case 1. A passage space for the reflected light inside the unit case 1 is separated from the other space in the unit case 1 by a partition member 6 placed on the mounting board 3 with an annular packing 5 therebetween which surrounds the light receiving element 4 and is made of an elastic material. The partition member 6 is provided with a pressing wall 7 configured to come into pressure contact with the outer peripheral wall of the annular packing 5 when the partition member 6 is placed on the mounting board 3, and thereby apply pressure contact force to the annular packing 5 while dividing the pressure contact force in a radially compressing direction, the pressure contact force being force with which the annular packing 5 comes into contact with the mounting board 3.

Abstract: A rotary switch includes a rotation movable portion, a movable conductor held in the rotation movable portion, a base portion, a power supply terminal held in the base portion, and a plurality of fixed contacts held in the base portion. The fixed contact and the power supply terminal are connected and disconnected via the movable conductor by a rotational operation of the rotation movable portion. The power supply terminal is disposed at a rotation center position of the rotation movable portion. The plurality of fixed contacts are disposed on a plurality of concentric circles having different diameter dimensions around the power supply terminal.

Abstract: A rotary switch device includes a fixed contact point part and a movable contact point part. The movable contact point part is rotated on the fixed contact point part so as to connect and disconnect the fixed contact point part and the movable contact point part. The fixed contact point part and the movable contact point part have contact surfaces which are band shapes and to which corrosion-resistant conductive processing is applied. A transient contact region, in which a contact point is moved from one end portion to the other end portion in a predetermined connection-operation angle from a contact start point with respect to the other of the fixed contact point part and the movable contact point part, is provided on each of the contact surfaces.
