PROBLEM TO BE SOLVED: To provide a flasher capable of easily controlling ON/OFF operation of a semiconductor switch which is connected to a mechanical contact switch being interposed by a resistance according to ON/OFF operation of the mechanical contact switch disposed on a power supply path to a load to thereby reduce the power consumption at turning On a load.SOLUTION: The flasher includes: a series circuit including a first mechanical contact switch and a semiconductor switch; and a series circuit including a second mechanical contact switch and a third mechanical contact switch, which are connected in parallel to each other on a power path for supplying the power from a power source to a load. The second mechanical contact switch and the third mechanical contact switch are connected to a trigger electrode the semiconductor switch being interposed by a resistance. When the first mechanical contact switch is in conductive state, the flasher controls the semiconductor switch to be conductive or non-conductive via the resistance depending on the state of conductive/non-conductive of the second mechanical contact switch. |
