利用光學(xué)元件，在傳播媒介中間使光束發(fā)生變化；利用光束來(lái)反射物體；使光束發(fā)射經(jīng)過(guò)長(zhǎng)距離后瞬間返回。光電開(kāi)關(guān)是由發(fā)射器、接收器和檢測(cè)電路三部分組成。發(fā)射器對(duì)準(zhǔn)目標(biāo)發(fā)射光束，發(fā)射的光束一般來(lái)源于發(fā)光二極管（LED）和激光二極管。光束不間斷地發(fā)射，或者改變脈沖寬度。受脈沖調(diào)制的光束輻射強(qiáng)度在發(fā)射中經(jīng)過(guò)多次選擇，朝著目標(biāo)不間接地運(yùn)行。接收器有光電二極管或光電三極管組成。在接收器的前面，裝有光學(xué)元件如透鏡和光圈等。在其后面的是檢測(cè)電路，它能濾出有效信號(hào)和應(yīng)用該信號(hào)。
