Abstract

PURPOSE:To obtain an inexpensive and miniaturized optical switch by comprising the light reflecting plane of a mirror with a half mirror and prohibiting the transmission of an unrequired optical signal out of the optical signals emitted from a receptacle to another receptacle when no electromagnet is driven. CONSTITUTION:The receptacle 1, a mirror 2, a mirror mounting part 5, a mounting part holding tool 6, the electromagnet 7, a case 8, a spring 9 and a spring mounting part 10 are provided. The optical signal emitted from the receptacle 1a is transmitted to the receptacle 1b when the electromagnet 7 is driven, and the optical signal from the receptacle 1c is transmitted to the receptacle 1d. Also, when no electromagnet 7 is driven, part of the optical signal from the receptacle 1a is reflected on the half-mirror plane 11 of the mirror 2, and is transmitted to the receptacle 1d, and also, the optical signal transmitting the half-mirror plane 11 is transmitted to the receptacle 1b as monitor light. Meanwhile, the optical signal from the receptacle 1c is shielded with a non- transmission part 12 formed on a plane opposing the half-mirror plane 11 of the mirror 2, and not being transmitted to another receptacles 1a, 1b, and 1d.
