Claims

[Claims for Utility Model Registration] (1) A casing in which a window is formed, an operating part that is movably supported within the casing and protrudes outside the casing and is moved by manipulating the protruding end, and an operating part. a biasing means having a movable part that biases the part in a predetermined direction and moves in conjunction with the movement of the operating part; a predetermined mark made at a position recognizable from the window part of the housing of the movable part; A non-contact point, characterized in that it is possible to project light from the outside onto the window of the housing and detect whether or not the operating section is operated based on a change in the reflectance of the reflected light from the mark on the moving object. Switch. (2) A housing having at least two windows formed therein; an operating unit that is movably supported within the housing and protrudes outside the housing and is moved by operating the protruding end; and the operating unit is moved in a predetermined direction. A biasing means having a movable part that biases and moves in conjunction with the movement of the operating part, and a predetermined mark made at a position recognizable from a window of a housing of the operating part or the movable part of the biasing means. , which projects light from the outside onto a predetermined window, reflects it from the mark on the operation part or the moving part in response to the operation of the operation part, and projects it to the outside from another window, and reflects the reflected light. A non-contact switch characterized in that the presence or absence of an operation on an operating section can be detected based on a change in rate.
