Abstract
This invention provides an optical relay that improves placement efficiency and space utilization through a stacked structure. [Solution] The optical relay includes a switching element 110, a photoelectric sensor 120, an insulating sheet 130, and a light-emitting element 140. The photoelectric sensor is laminated on the switching element and electrically connected to the switching element. The insulating sheet is laminated on the photoelectric sensor. The light-emitting element is laminated on the insulating sheet. The light-emitting element is suitable for generating an optical signal, which is transmitted to the photoelectric sensor after passing through the insulating sheet. After receiving the optical signal, the photoelectric sensor generates an electrical signal and transmits it to the switching element, and after receiving the electrical signal, the switching element outputs a control signal.
