Claims

[Claims for Utility Model Registration] (1) At least a pair of light emitting elements and light receiving elements provided in a case, and a spring, etc. that is movably inserted into a through hole provided on one side of the case and directed outward. A push button is provided with elasticity, and has a shutter function that integrally protrudes laterally from the push button and is inserted into and removed from the optical path from the light emitting element to the light receiving element in conjunction with pressing of the push button. A non-contact type micro switch characterized by consisting of an arm having a (2) The arm has an extension at its terminal end that extends in a horizontal direction perpendicular to the protruding direction of the arm and perpendicular to the pushing direction of the push button, and the extension moves in conjunction with pushing of the push button. A non-contact type micro switch according to claim 1, which is formed as a shutter plate that is inserted into and removed from an optical path from a light emitting element to a light receiving element. (3) The case includes a light emitting element for indicating an operation, which is provided in the case and emits light in response to the output of the light receiving element, and the light is led to the outside through a display window provided on the surface of the case. Characterized by
A non-contact type micro switch according to claim 1 of the utility model registration claim. (4) The contactless micro switch according to claim 3 of the utility model registration, characterized in that a transparent plate is used as the display window. (5) The non-contact type micro switch according to claim 3, wherein a lens made of a transparent material is used as the display window.
