Claims

[Scope of utility model registration request]

A snap acting mechanism constituted by a movable plate and a reversing spring is accommodated in the housing, and an operator for operating the snap acting mechanism is provided in the housing, and a pair of cylindrical collimator lenses is provided in the housing. are provided with their axes aligned so that they are optically connected to each other so that one end of each lens faces each other at a predetermined interval, and the other end of each lens is connected to one lens. One end of the light emitting optical fiber is optically connected to the other lens, one end of the light receiving optical fiber is optically connected to the other lens, and the other end of the light emitting optical fiber is optically connected to the light receiving element, and the housing Inside, the movable piece is provided with an optical switch that selectively opens and closes the light projected from one lens to the other between the two lenses, and the other end of each optical fiber is connected to the other end of each lens. An optical opening/closing device including a diaphragm located on the focal point and separating the snap acting mechanism and both lenses within the housing.
