ABSTRACT:
Provided are optical switches applicable to various safety apparatuses which can control an operation of a circuit by detecting a switching signal such as pathogens and toxic substances, and safety apparatuses using the optical switches. The optical switch comprises an optical irradiation unit to irradiate light; an optical interference unit which can interact with a switching signal, interferes with light irradiated from the optical irradiation unit and radiates it as interference light, and can vary the wavelength of the interference light after interaction with the switching signal; and a switching unit which is provided in the path of the interference light, detects a wavelength change of the interference light, and conducts one of activating and deactivating a circuit. The safety appatatus comprises the optical switch and a hazard evasive apparatus activating unit which activates a hazard evasive apparatus using the optical switch.
