ABSTRACT:
A photosemiconductor relay of the present invention comprises a light-emitting unit for emitting light therefrom, a light-receiving control circuit for providing a predetermined potential difference or more between a first connecting terminal and a second connecting terminal during a light-receiving period and electrically connecting the first and second connecting terminals to each other in response to the non-reception of the light, and a switching circuit for electrically connecting a first output terminal and a second output terminal to each other in response to the reception of the predetermined potential difference or more and restricting a load current flowing between the first and second output terminals to a predetermined value or less. Thus, since a current of a predetermined value or more does not flow into a load circuit connected between the output terminals, the load circuit is prevented from malfunctioning and the switching circuit is promptly turned off.
