A switch designed to perform the function of opening and/or closing one or more electrical circuits. In lieu of seperable contacts, the switching function is accomplished by means of an arrangement of one or more light emitters and one or more photosensitive devices. The item functions in response to changes in its own electrical circuit caused by the emitted light being reflected to the photosensitive device or the emitted light being interrupted before it reaches the photosensitive device. The item has no other form of actuation.
