Zusammenfassung:PROBLEM TO BE SOLVED: To provide a hybrid relay capable of preventing a semiconductor switch from getting highly heated. SOLUTION: The hybrid relay is provided with a mechanical contact switch 12 with its contact switched by a driving unit, and a semiconductor switch 13 connected in parallel with the mechanical contact switch 12, having a first power-feeding path by the mechanical contact switch 12 and a second power-feeding path by the semiconductor switch 13 connected in parallel as power-feeding paths supplying a load with a power source. It is provided with, for example, a thermal fuse F1 as a safety circuit section for opening the power-feeding path when temperature of the semiconductor switch becomes equal to or more than a prescribed temperature.
