The circuit board includes plural light emitters and plural light receivers. Each key is aligned with the corresponding light emitter and the corresponding light receiver. Moreover, each key includes a triggering element, a first reflective element and a second reflective element. When the triggering element is triggered by the user, a sensing light emitted by the light emitter is reflected to the second reflective element by the first reflective element. The sensing light is further reflected to the light receiver by the second reflective element. Consequently, the circuit board generates a key switch signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical switch keyboard","description":"An optical switch keyboard includes a circuit board and plural keys.
