<p>PURPOSE:To prevent the generation of chattering in switching operation and make the title switch long-lived by optically coupling light receiving components with a light emitting component by means of a mirrorlike surface and moving the mirrorlike surface so as to change over the light receiving components optically coupled with the light emitting component. CONSTITUTION:Light receiving components 3a, 3b are disposed in a package 1 in such a state as to be optically coupled with a light emitting component 2 independently by means of a mirrorlike surface 4 on which the light emitting component 2 and the light receiving components 3a, 3b move. A signal feeding conductor can be changed over between the signal conductors connected with the light receiving components 3a, 3b by moving the mirrorlike surface 4 so as to change over the light receiving components 3a, 3b optically coupled with the light emitting component 2. As a result, the generation of chattering is prevented in switching operation as well as the life-affecting part can be prevented from mechanical abrasion.</p> |
